DETECTING AND VALIDATING PLANNED EVENT INFORMATION
Abstract
The present invention extends to methods, systems, and computer
program products for detecting and validating planned event
information. The dimensionality of a raw signal is reduced into a
normalized signal that includes a probability value. The
probability value at least approximates a probability that the
normalized signal indicates that a real-world event of a specified
event type is occurring. Based on the at least approximated
probability, the real-world event of the specified event type is
detected as a possible planned event occurring at a venue. The
possible planned event is validated as an actual planned event.
Validation can include validating data associated with the possible
planned event with data from an event planning system associated
with the venue. An entity is electronically notified that the
actual planned event is occurring.

BACKGROUND
1. Background and Relevant Art
[0003] Data provided to computer systems can come from any number
of different sources, such as, for example, user input, files,
databases, applications, sensors, social media systems, cameras,
emergency communications, etc. In some environments, computer
systems receive (potentially large volumes of) data from a variety
of different domains and/or verticals in a variety of different
formats. When data is received from different sources and/or in
different formats, it can be difficult to efficiently and
effectively derive intelligence from the data.
[0004] Many entities desire to be made aware of planned events
(e.g., concerts, sporting events, theatre performances, etc.) as
well as changes to those planned events. Entities often refer to
the Internet, for example, to event information websites, to locate
information about planned events. However, different websites may
indicate different information about a planned event, including
start time, end time, venue, location, etc. Further, the
circumstances of a planned event can change leading to other
inconsistencies between event information websites.
[0005] Some events may be associated with an authoritative web set.
For example, professional sports teams typically have their own
"official" website and/or an "official" league website indicating
when and where games are to be played. However, information
aggregation websites and other meta websites often take the
information from "official" sites and repurpose it. People use such
sites to more efficiently access information for multiple events.
For example, if a person is interested in all the sporting
activities in their area, it may be more efficient to visit an
information aggregation website than individually check multiple
team and/or league websites. Unfortunately, each time information
is obtained and repurposed there is some chance of information loss
and/or contextual loss.
[0006] Further, due to unforeseen circumstances, the date and/or
time of planned events can change, the location of planned events
can change, planned events can be canceled, etc. Unforeseen
circumstances can include natural disasters, venue issues (e.g.,
technical, legal, etc.), talent issues (e.g., illness, legal,
etc.), other overriding events (e.g., visiting dignitaries), etc.
When a planned event is changed, changes may be initially posted at
an "official" website. However, it may take some amount of time for
changed information posted to "official" web sites to propagate
through to aggregation websites and other meta websites. Further,
different aggregation websites and other meta websites may acquire
and/or update changed information at different times. Thus, at any
given time, there can be inconsistencies in planned event
information available online.
BRIEF SUMMARY

information.
[0008] The dimensionality of a raw signal is reduced into a

probability, the real-world event of the specified event type is

DETAILED DESCRIPTION
[0024] Examples extend to methods, systems, and computer program
products for detecting and validating planned event
information.
[0025] Entities (e.g., parents, other family members, guardians,
friends, teachers, social workers, first responders, hospitals,
delivery services, media outlets, government entities, etc.) may
desire to be made aware of planned events and changes to planned
events. Different types of ingested signals (e.g., social media
signals, web signals, and streaming signals) can be used to detect
events. Entities may desire to be made aware of changes to relevant
events as close as possible to the changes' occurrence (i.e., as
close as possible to "moment zero").
[0026] In general, signal ingestion modules ingest different types
of raw structured and/or raw unstructured signals on an ongoing
basis. Different types of signals can include different data media
types and different data formats, including Web signals. Different
types of signals can include different data media types and
different data formats. Data media types can include audio, video,
image, and text. Different formats can include text in XML, text in
JavaScript Object Notation (JSON), text in RSS feed, plain text,
video stream in Dynamic Adaptive Streaming over HTTP (DASH), video
stream in HTTP Live Streaming (HLS), video stream in Real-Time
Messaging Protocol (RTMP), other Multipurpose Internet Mail
Extensions (MIME) types, etc. Handling different types and formats
of data introduces inefficiencies into subsequent event detection
processes, including when determining if different signals relate
to the same event.
[0027] Accordingly, the signal ingestion modules can normalize raw
signals across multiple data dimensions to form normalized signals.
Each dimension can be a scalar value or a vector of values. In one
aspect, raw signals are normalized into normalized signals having a
Time, Location, Context (or "TLC") dimensions.
[0028] A Time (T) dimension can include a time of origin or
alternatively a "event time" of a signal. A Location (L) dimension
can include a location anywhere across a geographic area, such as,
a country (e.g., the United States), a State, a defined area, an
impacted area, an area defined by a geo cell, an address, etc.
[0029] A Context (C) dimension indicates circumstances surrounding
formation/origination of a raw signal in terms that facilitate
understanding and assessment of the raw signal. The Context (C)
dimension of a raw signal can be derived from express as well as
inferred signal features of the raw signal.
[0030] Signal ingestion modules can include one or more single
source classifiers. A single source classifier can compute a single
source probability for a raw signal from features of the raw
signal. A single source probability can reflect a mathematical
probability or approximation of a mathematical probability (e.g., a
percentage between 0%-100%) of an event actually occurring. A
single source classifier can be configured to compute a single
source probability for a single event type or to compute a single
source probability for each of a plurality of different event
types. A single source classifier can compute a single source
probability using artificial intelligence, machine learning, neural
networks, logic, heuristics, etc.
[0031] As such, single source probabilities and corresponding
probability details can represent a Context (C) dimension.
Probability details can indicate (e.g., can include a hash field
indicating) a probabilistic model and (express and/or inferred)
signal features considered in a signal source probability
calculation.
[0032] Thus, per signal type, signal ingestion modules determine
Time (T), a Location (L), and a Context (C) dimensions associated
with a signal. Different ingestion modules can be utilized/tailored
to determine T, L, and C dimensions associated with different
signal types. Normalized (or "TLC") signals can be forwarded to an
event detection infrastructure. When signals are normalized across
common dimensions subsequent event detection is more efficient and
more effective.
[0033] Normalization of ingestion signals can include
dimensionality reduction. Generally, "transdimensionality"
transformations can be structured and defined in a "TLC"
dimensional model. Signal ingestion modules can apply the
"transdimensionality" transformations to generic source data in raw
signals to re-encode the source data into normalized data having
lower dimensionality. Thus, each normalized signal can include a T
vector, an L vector, and a C vector. At lower dimensionality, the
complexity of measuring "distances" between dimensional vectors
across different normalized signals is reduced.
[0034] Concurrently with signal ingestion, an event detection
infrastructure considers features of different combinations of
normalized signals to attempt to identify events of interest to
various parties. For example, the event detection infrastructure
can determine that features of multiple different normalized
signals collectively indicate an event of interest to one or more
parties. Alternately, the event detection infrastructure can
determine that features of one or more normalized signals indicate
a possible event of interest to one or more parties. The event
detection infrastructure then determines that features of one or
more other normalized signals validate the possible event as an
actual event of interest to the one or more parties. The event
infrastructure can similarly detect changes to events, including
changes to planned events. Signal features can include: signal
type, signal source, signal content, Time (T) dimension, Location
(L) dimension, Context (C) dimension, other circumstances of signal
creation, etc. In one aspect, the event detection infrastructure
receives a normalized (e.g., Web) signal from the signal ingestion
modules. The event detection infrastructure detects a possible
planned event based on characteristics of the normalized signal.
The event detection infrastructure derives event features
associated with the possible planned event, including an event
location, an event date, and event times. An event history of one
or more prior events at the event location can also be accessed.
Signals can expressly include one or more event features. One or
more other event features can be inferred via a combination of
historical datasets, machine learning, and heuristics.
[0035] An event context is derived from the characteristics of the
normalized signal and the contents of the event history. The event
context is submitted to a planning system potentially associated
with a planned event at the event location. Validating data is
received from the planning system. The possible planned event is
validated as the planned event based on the validating data.
[0036] In another aspect, the event detection infrastructure
receives a plurality of normalized (e.g., Web) signals providing
details of a planned event. Each signal can be from a different
source. Automated mechanisms (e.g., machine learning, artificial
intelligence, neural networks, etc.) can be used to determine
truthful information related to the planned event. In one aspect,
multiple sources (e.g., multiple websites) provide consistent
(e.g., substantively concurring) event information associated with
a planned event. That is, the multiple sources can indicate
essentially the same date, same start time, same end time, same
location, same description, etc. for a planned event. In this
aspect, machine learning, artificial intelligence, neural networks,
etc. can be used to automatically validate event information from
the multiple sources with one another.
[0037] In further aspect, different sources provide inconsistent
(e.g., differing) event information associated with a planned
event. That is, one source can indicate one or more categories, a
date, a start time, an end time, a location, a description, etc.
for a planned event. Another source can indicate one or more other
categories, another date, another start time, another end time,
another location, another description, etc. for a planned event.
Categories can include a type of event (e.g., sporting event,
convert, convention, etc.) as well as event participants (e.g.,
teams, musicians, etc.) At least one of the one or more categories,
the dates, the start times, the end times, the locations, and the
descriptions can meaningfully differ from one another. Machine
learning, artificial intelligence, neural networks, etc. can be
used to automatically resolve discrepancies, disagreements, etc. in
event information from different sources. Discrepancies,
disagreements, etc. not automatically resolved can be forwarded to
other resolution systems.
[0038] Accordingly, aspects of the invention increase the
likelihood of providing accurate event information regarding
changes to a planned event to entities interested in the planned
event. For example, entities are more likely to receive accurate
event information when a planned event is rescheduled, relocated,
or canceled.
[0039] Surrounding activities (or other events) associated with a
planned event can also be monitored and/or detected. Some entities,
including first responders, may be interested in surrounding
activities. In this respect, one planned event can trigger
additional planned events. For example, a concert can trigger a
traffic management event for a police department, establishment of
medical staging areas event for paramedics, etc. Information about
these events can also be provided by one or more sources. Event
information about these activities or other events can be provided
in a similar automated fashion.
[0040] In one aspect, entities register to be automatically
notified of changes to relevant planned events. When changes to
relevant planned events are detected, the entities are
automatically notified.
[0041] Implementations can comprise or utilize a special purpose or
general-purpose computer including computer hardware, such as, for
example, one or more computer and/or hardware processors (including
any of Central Processing Units (CPUs), and/or Graphical Processing
Units (GPUs), general-purpose GPUs (GPGPUs), Field Programmable
Gate Arrays (FPGAs), application specific integrated circuits
(ASICs), Tensor Processing Units (TPUs)) and system memory, as
discussed in greater detail below. Implementations also include
physical and other computer-readable media for carrying or storing
computer-executable instructions and/or data structures. Such
computer-readable media can be any available media that can be
accessed by a general purpose or special purpose computer system.
Computer-readable media that store computer-executable instructions
are computer storage media (devices). Computer-readable media that
carry computer-executable instructions are transmission media.
Thus, by way of example, and not limitation, implementations can
comprise at least two distinctly different kinds of
computer-readable media: computer storage media (devices) and
transmission media.
[0042] Computer storage media (devices) includes RAM, ROM, EEPROM,
CD-ROM, Solid State Drives ("SSDs") (e.g., RAM-based or
Flash-based), Shingled Magnetic Recording ("SMR") devices, Flash
memory, phase-change memory ("PCM"), other types of memory, other
optical disk storage, magnetic disk storage or other magnetic
storage devices, or any other medium which can be used to store
desired program code means in the form of computer-executable
instructions or data structures and which can be accessed by a
general purpose or special purpose computer.
[0043] In one aspect, one or more processors are configured to
execute instructions (e.g., computer-readable instructions,
computer-executable instructions, etc.) to perform any of a
plurality of described operations. The one or more processors can
access information from system memory and/or store information in
system memory. The one or more processors can (e.g., automatically)
transform information between different formats, such as, for
example, between any of: raw signals, normalized signals, partially
normalized signals, signal features, single source probabilities,
times, time dimensions, locations, location dimensions, context
dimensions, geo cells, geo cell entries, geo cell queries, search
terms, events, possible events, signal features, planned events,
possible planned events, event context, validating data, venues,
etc.
[0044] System memory can be coupled to the one or more processors
and can store instructions (e.g., computer-readable instructions,
computer-executable instructions, etc.) executed by the one or more
processors. The system memory can also be configured to store any
of a plurality of other types of data generated and/or transformed
by the described components, such as, for example, raw signals,
normalized signals, partially normalized signals, signal features,
single source probabilities, times, time dimensions, locations,
location dimensions, context dimensions, geo cells, geo cell
entries, geo cell queries, search terms, events, possible events,
signal features, planned events, possible planned events, event
context, validating data, venues, etc.
[0045] A "network" is defined as one or more data links that enable
the transport of electronic data between computer systems and/or
modules and/or other electronic devices. When information is
transferred or provided over a network or another communications
connection (either hardwired, wireless, or a combination of
hardwired or wireless) to a computer, the computer properly views
the connection as a transmission medium. Transmissions media can
include a network and/or data links which can be used to carry
desired program code means in the form of computer-executable
instructions or data structures and which can be accessed by a
general purpose or special purpose computer. Combinations of the
above should also be included within the scope of computer-readable
media.
[0046] Further, upon reaching various computer system components,
program code means in the form of computer-executable instructions
or data structures can be transferred automatically from
transmission media to computer storage media (devices) (or vice
versa). For example, computer-executable instructions or data
structures received over a network or data link can be buffered in
RAM within a network interface module (e.g., a "NIC"), and then
eventually transferred to computer system RAM and/or to less
volatile computer storage media (devices) at a computer system.
Thus, it should be understood that computer storage media (devices)
can be included in computer system components that also (or even
primarily) utilize transmission media.
[0047] Computer-executable instructions comprise, for example,
instructions and data which, in response to execution at a
processor, cause a general purpose computer, special purpose
computer, or special purpose processing device to perform a certain
function or group of functions. The computer executable
instructions may be, for example, binaries, intermediate format
instructions such as assembly language, or even source code.
Although the subject matter has been described in language specific
to structural features and/or methodological acts, it is to be
understood that the subject matter defined in the appended claims
is not necessarily limited to the described features or acts
described above. Rather, the described features and acts are
disclosed as example forms of implementing the claims.
[0048] Those skilled in the art will appreciate that the described
aspects may be practiced in network computing environments with
many types of computer system configurations, including, personal
computers, desktop computers, laptop computers, message processors,
hand-held devices, wearable devices, multicore processor systems,
multi-processor systems, microprocessor-based or programmable
consumer electronics, network PCs, minicomputers, mainframe
computers, mobile telephones, PDAs, tablets, routers, switches, and
the like. The described aspects may also be practiced in
distributed system environments where local and remote computer
systems, which are linked (either by hardwired data links, wireless
data links, or by a combination of hardwired and wireless data
links) through a network, both perform tasks. In a distributed
system environment, program modules may be located in both local
and remote memory storage devices.
[0049] Further, where appropriate, functions described herein can
be performed in one or more of: hardware, software, firmware,
digital components, or analog components. For example, one or more
Field Programmable Gate Arrays (FPGAs) and/or one or more
application specific integrated circuits (ASICs) and/or one or more
Tensor Processing Units (TPUs) can be programmed to carry out one
or more of the systems and procedures described herein. Hardware,
software, firmware, digital components, or analog components can be
specifically tailor-designed for a higher speed detection or
artificial intelligence that can enable signal processing. In
another example, computer code is configured for execution in one
or more processors, and may include hardware logic/electrical
circuitry controlled by the computer code. These example devices
are provided herein purposes of illustration, and are not intended
to be limiting. Embodiments of the present disclosure may be
implemented in further types of devices.
[0050] The described aspects can also be implemented in cloud
computing environments. In this description and the following
claims, "cloud computing" is defined as a model for enabling
on-demand network access to a shared pool of configurable computing
resources. For example, cloud computing can be employed in the
marketplace to offer ubiquitous and convenient on-demand access to
the shared pool of configurable computing resources (e.g., compute
resources, networking resources, and storage resources). The shared
pool of configurable computing resources can be provisioned via
virtualization and released with low effort or service provider
interaction, and then scaled accordingly.
[0051] A cloud computing model can be composed of various
characteristics such as, for example, on-demand self-service, broad
network access, resource pooling, rapid elasticity, measured
service, and so forth. A cloud computing model can also expose
various service models, such as, for example, Software as a Service
("SaaS"), Platform as a Service ("PaaS"), and Infrastructure as a
Service ("IaaS"). A cloud computing model can also be deployed
using different deployment models such as private cloud, community
cloud, public cloud, hybrid cloud, and so forth. In this
description and in the following claims, a "cloud computing
environment" is an environment in which cloud computing is
employed.
[0052] In this description and the following claims, a "geo cell"
is defined as a piece of "cell" in a spatial grid in any form. In
one aspect, geo cells are arranged in a hierarchical structure.
Cells of different geometries can be used.
[0053] A "geohash" is an example of a "geo cell".
[0054] In this description and the following claims, "geohash" is
defined as a geocoding system which encodes a geographic location
into a short string of letters and digits. Geohash is a
hierarchical spatial data structure which subdivides space into
buckets of grid shape (e.g., a square). Geohashes offer properties
like arbitrary precision and the possibility of gradually removing
characters from the end of the code to reduce its size (and
gradually lose precision). As a consequence of the gradual
precision degradation, nearby places will often (but not always)
present similar prefixes. The longer a shared prefix is, the closer
the two places are. geo cells can be used as a unique identifier
and to approximate point data (e.g., in databases).
[0055] In one aspect, a "geohash" is used to refer to a string
encoding of an area or point on the Earth. The area or point on the
Earth may be represented (among other possible coordinate systems)
as a latitude/longitude or Easting/Northing--the choice of which is
dependent on the coordinate system chosen to represent an area or
point on the Earth. geo cell can refer to an encoding of this area
or point, where the geo cell may be a binary string comprised of 0s
and 1s corresponding to the area or point, or a string comprised of
0s, 1s, and a ternary character (such as X)--which is used to refer
to a don't care character (0 or 1). A geo cell can also be
represented as a string encoding of the area or point, for example,
one possible encoding is base-32, where every 5 binary characters
are encoded as an ASCII character.
[0056] Depending on latitude, the size of an area defined at a
specified geo cell precision can vary. When geohash is used for
spatial indexing, the areas defined at various geo cell precisions
are approximately:
TABLE-US-00001 TABLE 1 Example Areas at Various Geohash Precisions
Geohash Length/Precision width .times. height 1 5,009.4 km .times.
4,992.6 km 2 1,252.3 km .times. 624.1 km.sup. 3 156.5 km .times.
156 km.sup. 4 39.1 km .times. 19.5 km 5 4.9 km .times. 4.9 km 6 1.2
km .times. 609.4 m 7 152.9 m .times. 152.4 m 8 38.2 m .times. 19
m.sup. 9 4.8 m .times. 4.8 m 10 1.2 m .times. 59.5 cm 11 14.9 cm
.times. 14.9 cm 12 3.7 cm .times. 1.9 cm
[0057] Other geo cell geometries, such as, hexagonal tiling,
triangular tiling, etc. are also possible. For example, the H3
geospatial indexing system is a multi-precision hexagonal tiling of
a sphere (such as the Earth) indexed with hierarchical linear
indexes.
[0058] In another aspect, geo cells are a hierarchical
decomposition of a sphere (such as the Earth) into representations
of regions or points based a Hilbert curve (e.g., the S2 hierarchy
or other hierarchies). Regions/points of the sphere can be
projected into a cube and each face of the cube includes a
quad-tree where the sphere point is projected into. After that,
transformations can be applied and the space discretized. The geo
cells are then enumerated on a Hilbert Curve (a space-filling curve
that converts multiple dimensions into one dimension and preserves
the approximate locality).
[0059] Due to the hierarchical nature of geo cells, any signal,
event, entity, etc., associated with a geo cell of a specified
precision is by default associated with any less precise geo cells
that contain the geo cell. For example, if a signal is associated
with a geo cell of precision 9, the signal is by default also
associated with corresponding geo cells of precisions 1, 2, 3, 4,
5, 6, 7, and 8. Similar mechanisms are applicable to other tiling
and geo cell arrangements. For example, S2 has a cell level
hierarchy ranging from level zero (85,011,012 km.sup.2) to level 30
(between 0.48 cm.sup.2 to 0.96 cm.sup.2).
[0060] Signal Ingestion and Normalization
[0061] Signal ingestion modules ingest a variety of raw structured
and/or raw unstructured signals on an on going basis and in
essentially real-time. Raw signals can include social posts, live
broadcasts, traffic camera feeds, other camera feeds (e.g., from
other public cameras or from CCTV cameras), listening device feeds,
911 calls, weather data, planned events, IoT device data, crowd
sourced traffic and road information, satellite data, air quality
sensor data, smart city sensor data, public radio communication
(e.g., among first responders and/or dispatchers, between air
traffic controllers and pilots), etc. The content of raw signals
can include images, video, audio, text, etc.
[0062] In general, signal normalization can prepare (or
pre-process) raw signals into normalized signals to increase
efficiency and effectiveness of subsequent computing activities,
such as, event detection, event notification, etc., that utilize
the normalized signals. For example, signal ingestion modules can
normalize raw signals, including raw streaming signals, into
normalized signals having a Time, Location, and Context (TLC)
dimensions. An event detection infrastructure can use the Time,
Location, and Content dimensions to more efficiently and
effectively detect events.
[0063] Per signal type and signal content, different normalization
modules can be used to extract, derive, infer, etc. Time, Location,
and Context dimensions from/for a raw signal. For example, one set
of normalization modules can be configured to extract/derive/infer
Time, Location and Context dimensions from/for social signals.
Another set of normalization modules can be configured to
extract/derive/infer Time, Location and Context dimensions from/for
Web signals. A further set of normalization modules can be
configured to extract/derive/infer Time, Location and Context
dimensions from/for streaming signals.
[0064] Normalization modules for extracting/deriving/inferring
Time, Location, and Context dimensions can include text processing
modules, NLP modules, image processing modules, video processing
modules, etc. The modules can be used to extract/derive/infer data
representative of Time, Location, and Context dimensions for a
signal. Time, Location, and Context dimensions for a signal can be
extracted/derived/inferred from metadata and/or content of the
signal.
[0065] For example, NLP modules can analyze metadata and content of
a sound clip to identify a time, location, and keywords (e.g.,
fire, shooter, etc.). An acoustic listener can also interpret the
meaning of sounds in a sound clip (e.g., a gunshot, vehicle
collision, etc.) and convert to relevant context. Live acoustic
listeners can determine the distance and direction of a sound.
Similarly, image processing modules can analyze metadata and pixels
in an image to identify a time, location and keywords (e.g., fire,
shooter, etc.). Image processing modules can also interpret the
meaning of parts of an image (e.g., a person holding a gun, flames,
a store logo, etc.) and convert to relevant context. Other modules
can perform similar operations for other types of content including
text and video.
[0066] Per signal type, each set of normalization modules can
differ but may include at least some similar modules or may share
some common modules. For example, similar (or the same) image
analysis modules can be used to extract named entities from social
signal images and public camera feeds. Likewise, similar (or the
same) NLP modules can be used to extract named entities from social
signal text and web text.
[0067] In some aspects, an ingested signal includes sufficient
expressly defined time, location, and context information upon
ingestion. The expressly defined time, location, and context
information is used to determine Time, Location, and Context
dimensions for the ingested signal. In other aspects, an ingested
signal lacks expressly defined location information or expressly
defined location information is insufficient (e.g., lacks
precision) upon ingestion. In these other aspects, Location
dimension or additional Location dimension can be inferred from
features of an ingested signal and/or through references to other
data sources. In further aspects, an ingested signal lacks
expressly defined context information or expressly defined context
information is insufficient (e.g., lacks precision) upon ingestion.
In these further aspects, Context dimension or additional Context
dimension can be inferred from features of an ingested signal
and/or through reference to other data sources.
[0068] In additional aspects, time information may not be included,
or included time information may not be given with high enough
precision and Time dimension is inferred. For example, a user may
post an image to a social network which had been taken some
indeterminate time earlier.
[0069] Normalization modules can use named entity recognition and
reference to a geo cell database to infer Location dimension. Named
entities can be recognized in text, images, video, audio, or sensor
data. The recognized named entities can be compared to named
entities in geo cell entries. Matches indicate possible signal
origination in a geographic area defined by a geo cell.
[0070] As such, a normalized signal can include a Time dimension, a
Location dimension, a Context dimension (e.g., single source
probabilities and probability details), a signal type, a signal
source, and content.
[0071] A single source probability can be calculated by single
source classifiers (e.g., machine learning models, artificial
intelligence, neural networks, statistical models, etc.) that
consider hundreds, thousands, or even more signal features of a
signal. Single source classifiers can be based on binary models
and/or multi-class models.
[0072] FIG. 1A depicts part of computer architecture 100 that
facilitates ingesting and normalizing signals. As depicted,
computer architecture 100 includes signal ingestion modules 101,
social signals 171, Web signals 172, and streaming signals 173.
Signal ingestion modules 101, social signals 171, Web signals 172,
and streaming signals 173 can be connected to (or be part of) a
network, such as, for example, a system bus, a Local Area Network
("LAN"), a Wide Area Network ("WAN"), and even the Internet.
Accordingly, signal ingestion modules 101, social signals 171, Web
signals 172, and streaming signals 173 as well as any other
connected computer systems and their components can create and
exchange message related data (e.g., Internet Protocol ("IP")
datagrams and other higher layer protocols that utilize IP
datagrams, such as, Transmission Control Protocol ("TCP"),
Hypertext Transfer Protocol ("HTTP"), Simple Mail Transfer Protocol
("SMTP"), Simple Object Access Protocol (SOAP), etc. or using other
non-datagram protocols) over the network.
[0073] Signal ingestion module(s) 101 can ingest raw signals 121,
including social signals 171, web signals 172, and streaming
signals 173 (e.g., social posts, traffic camera feeds, other camera
feeds, listening device feeds, 911 calls, weather data, planned
events, IoT device data, crowd sourced traffic and road
information, satellite data, air quality sensor data, smart city
sensor data, public radio communication, etc.) on going basis and
in essentially real-time. Signal ingestion module(s) 101 include
social content ingestion modules 174, web content ingestion modules
175, stream content ingestion modules 176, and signal formatter
180. Signal formatter 180 further includes social signal processing
module 181, web signal processing module 182, and stream signal
processing modules 183.
[0074] Streaming signals 173 can include live video and/or non-live
(previously stored) video.
[0075] For each type of signal, a corresponding ingestion module
and signal processing module can interoperate to normalize the
signal along Time, Location, Context (TLC) dimensions. For example,
social content ingestion modules 174 and social signal processing
module 181 can interoperate to normalize social signals 171 into
TLC dimensions. Similarly, web content ingestion modules 175 and
web signal processing module 182 can interoperate to normalize web
signals 172 into TLC dimensions. Likewise, stream content ingestion
modules 176 and stream signal processing modules 183 can
interoperate to normalize streaming signals 173 into TLC
dimensions.
[0076] In one aspect, signal content exceeding specified size
requirements (e.g., audio or video) is cached upon ingestion.
Signal ingestion modules 101 include a URL or other identifier to
the cached content within the context for the signal.
[0077] In one aspect, signal formatter 180 includes modules for
determining a single source probability as a ratio of signals
turning into events based on the following signal properties: (1)
event class (e.g., fire, accident, weather, etc.), (2) media type
(e.g., text, image, audio, etc.), (3) source (e.g., twitter,
traffic camera, first responder radio traffic, etc.), and (4) geo
type (e.g., geo cell, region, or non-geo). Probabilities can be
stored in a lookup table for different combinations of the signal
properties. Features of a signal can be derived and used to query
the lookup table. For example, the lookup table can be queried with
terms ("accident", "image", "twitter", "region"). The corresponding
ratio (probability) can be returned from the table.
[0078] In another aspect, signal formatter 180 includes a plurality
of single source classifiers (e.g., artificial intelligence,
machine learning modules, neural networks, etc.). Each single
source classifier can consider hundreds, thousands, or even more
signal features of a signal. Signal features of a signal can be
derived and submitted to a signal source classifier. The single
source classifier can return a probability that a signal indicates
a type of event. Single source classifiers can be binary
classifiers or multi-source classifiers.
[0079] Raw classifier output can be adjusted to more accurately
represent a probability that a signal is a "true positive". For
example, 1,000 signals whose raw classifier output is 0.9 may
include 80% as true positives. Thus, probability can be adjusted to
0.8 to reflect true probability of the signal being a true
positive. "Calibration" can be done in such a way that for any
"calibrated score" this score reflects the true probability of a
true positive outcome.
[0080] Signal ingestion modules 101 can insert one or more single
source probabilities and corresponding probability details into a
normalized signal to represent a Context (C) dimension. Probability
details can indicate a probabilistic model and features used to
calculate the probability. In one aspect, a probabilistic model and
signal features are contained in a hash field.
[0081] Signal ingestion modules 101 can access
"transdimensionality" transformations structured and defined in a
"TLC" dimensional model. Signal ingestion modules 101 can apply the
"transdimensionality" transformations to generic source data in raw
signals to re-encode the source data into normalized data having
lower dimensionality. Dimensionality reduction can include reducing
dimensionality of a raw signal to a normalized signal including a T
vector, an L vector, and a C vector. At lower dimensionality, the
complexity and resource consumption of measuring "distances"
between dimensional vectors across different normalized signals is
reduced.
[0082] Thus, in general, any received raw signals can be normalized
into normalized signals including a Time (T) dimension, a Location
(L) dimension, a Context (C) dimension, signal source, signal type,
and content. Signal ingestion modules 101 can send normalized
signals 122 to event detection infrastructure 103.
[0083] For example, signal ingestion modules 101 can send
normalized signal 122A, including time (dimension) 123A, location
(dimension) 124A, context (dimension) 126A, content 127A, type
128A, and source 129A to event detection infrastructure 103.
Similarly, signal ingestion modules 101 can send normalized signal
122B, including time (dimension) 123B, location (dimension) 124B,
context (dimension) 126B, content 127B, type 128B, and source 129B
to event detection infrastructure 103.
[0084] Event Detection
[0085] FIG. 1B depicts part of computer architecture 100 that
facilitates detecting events. As depicted, computer architecture
100 includes geo cell database 111 and even notification 116. Geo
cell database 111 and event notification 116 can be connected to
(or be part of) a network with signal ingestion modules 101 and
event detection infrastructure 103. As such, geo cell database 111
and even notification 116 can create and exchange message related
data over the network.
[0086] As described, in general, on an ongoing basis, concurrently
with signal ingestion (and also essentially in real-time), event
detection infrastructure 103 detects different categories of
(planned and unplanned) events (e.g., fire, police response, mass
shooting, traffic accident, natural disaster, storm, active
shooter, concerts, protests, etc.) in different locations (e.g.,
anywhere across a geographic area, such as, the United States, a
State, a defined area, an impacted area, an area defined by a geo
cell, an address, etc.), at different times from Time, Location,
and Context dimensions included in normalized signals. Event
detection infrastructure can likewise detect changes to existing
(planned and unplanned) events. Since, normalized signals are
normalized to include Time, Location, and Context dimensions
(vectors), event detection infrastructure 103 can handle normalized
signals in a more uniform manner Handling signals in a more uniform
manner increases event detection and event change detection
efficiency and effectiveness and also reduces resource consumption.
For example, Time, Location, and Context vectors of different
normalized signals can be compared (instead of comparing along
numerous other dimensions).
[0087] Event detection infrastructure 103 can also determine an
event truthfulness (e.g., erroneous detection results, detections
based on tampered source data, detections of fictional or staged
events), event severity, and an associated geo cell. In one aspect,
context information in a normalized signal increases the efficiency
and effectiveness of determining truthfulness, severity, and an
associated geo cell.
[0088] Generally, an event truthfulness indicates how likely a
detected event is actually an event (vs. a hoax, fake,
misinterpreted, etc.). Truthfulness can range from less likely to
be true to more likely to be true. In one aspect, truthfulness is
represented as a numerical value, such as, for example, from 1
(less truthful) to 10 (more truthful) or as percentage value in a
percentage range, such as, for example, from 0% (less truthful) to
100% (more truthful). Other truthfulness representations are also
possible. For example, truthfulness can be a dimension and/or can
be represented by one or more vectors.
[0089] Generally, an event severity indicates how severe an event
is (e.g., what degree of badness, what degree of damage, etc. is
associated with the event). Severity can range from less severe
(e.g., a single vehicle accident without injuries) to more severe
(e.g., multi vehicle accident with multiple injuries and a possible
fatality). As another example, a shooting event can also range from
less severe (e.g., one victim without life threatening injuries) to
more severe (e.g., multiple injuries and multiple fatalities). In
one aspect, severity is represented as a numerical value, such as,
for example, from 1 (less severe) to 5 (more severe). Other
severity representations are also possible. For example, severity
can be a dimension and/or can be represented by one or more
vectors.
[0090] In general, event detection infrastructure 103 can include a
geo determination module including modules for processing different
kinds of content including location, time, context, text, images,
audio, and video into search terms. The geo determination module
can query a geo cell database with search terms formulated from
normalized signal content. The geo cell database can return any geo
cells having matching supplemental information. For example, if a
search term includes a street name, a subset of one or more geo
cells including the street name in supplemental information can be
returned to the event detection infrastructure.
[0091] Event detection infrastructure 103 can use the subset of geo
cells to determine a geo cell associated with an event location.
Events associated with a geo cell can be stored back into an entry
for the geo cell in the geo cell database. Thus, over time an
historical progression of events within a geo cell can be
accumulated.
[0092] As such, event detection infrastructure 103 can assign an
event ID, an event time, an event location, an event category, an
event description, an event truthfulness, and an event severity to
each detected event. Detected events can be sent to relevant
entities, including to mobile devices, to computer systems, to
APIs, to data storage, etc.
[0093] Event detection infrastructure 103 detects events from
information contained in normalized signals 122. Event detection
infrastructure 103 can detect an event from a single normalized
signal 122 or from multiple normalized signals 122. In one aspect,
event detection infrastructure 103 detects an event based on
information contained in one or more normalized signals 122. In
another aspect, event detection infrastructure 103 detects a
possible event based on information contained in one or more
normalized signals 122. Event detection infrastructure 103 then
validates the potential event as an event based on information
contained in one or more other normalized signals 122.
[0094] As depicted, event detection infrastructure 103 includes geo
determination module 104, categorization module 106, truthfulness
determination module 107, and severity determination module
108.
[0095] Geo determination module 104 can include NLP modules, image
analysis modules, etc. for identifying location information from a
normalized signal. Geo determination module 104 can formulate
(e.g., location) search terms 141 by using NLP modules to process
audio, using image analysis modules to process images, etc. Search
terms can include street addresses, building names, landmark names,
location names, school names, image fingerprints, etc. Event
detection infrastructure 103 can use a URL or identifier to access
cached content when appropriate.
[0096] Categorization module 106 can categorize a detected event
into one of a plurality of different categories (e.g., fire, police
response, mass shooting, traffic accident, natural disaster, storm,
active shooter, concerts, protests, etc.) based on the content of
normalized signals used to detect and/or otherwise related to an
event.
[0097] Truthfulness determination module 107 can determine the
truthfulness of a detected event based on one or more of: source,
type, age, and content of normalized signals used to detect and/or
otherwise related to the event. Some signal types may be inherently
more reliable than other signal types. For example, video from a
live traffic camera feed may be more reliable than text in a social
media post. Some signal sources may be inherently more reliable
than others. For example, a social media account of a government
agency may be more reliable than a social media account of an
individual. The reliability of a signal can decay over time.
[0098] Severity determination module 108 can determine the severity
of a detected event based on or more of: location, content (e.g.,
dispatch codes, keywords, etc.), and volume of normalized signals
used to detect and/or otherwise related to an event. Events at some
locations may be inherently more severe than events at other
locations. For example, an event at a hospital is potentially more
severe than the same event at an abandoned warehouse. Event
category can also be considered when determining severity. For
example, an event categorized as a "Shooting" may be inherently
more severe than an event categorized as "Police Presence" since a
shooting implies that someone has been injured.
[0099] Geo cell database 111 includes a plurality of geo cell
entries. Each geo cell entry is included in a geo cell defining an
area and corresponding supplemental information about things
included in the defined area. The corresponding supplemental
information can include latitude/longitude, street names in the
area defined by and/or beyond the geo cell, businesses in the area
defined by the geo cell, other Areas of Interest (AOIs) (e.g.,
event venues, such as, arenas, stadiums, theaters, concert halls,
etc.) in the area defined by the geo cell, image fingerprints
derived from images captured in the area defined by the geo cell,
and prior events that have occurred in the area defined by the geo
cell. For example, geo cell entry 151 includes geo cell 152,
lat/lon 153, streets 154, businesses 155, AOIs 156, and prior
events 157. Each event in prior events 157 can include a location
(e.g., a street address), a time (event occurrence time), an event
category, an event truthfulness, an event severity, and an event
description. Similarly, geo cell entry 161 includes geo cell 162,
lat/lon 163, streets 164, businesses 165, AOIs 166, and prior
events 167. Each event in prior events 167 can include a location
(e.g., a street address), a time (event occurrence time), an event
category, an event truthfulness, an event severity, and an event
description.
[0100] Other geo cell entries can include the same or different
(more or less) supplemental information, for example, depending on
infrastructure density in an area. For example, a geo cell entry
for an urban area can contain more diverse supplemental information
than a geo cell entry for an agricultural area (e.g., in an empty
field). Sufficiently precise geo cells can be used to increase the
practicality of storing matching content.
[0101] Geo cell database 111 can store geo cell entries in a
hierarchical arrangement based on geo cell precision. As such, geo
cell information of more precise geo cells is included in the geo
cell information for any less precise geo cells that include the
more precise geo cell.
[0102] Geo determination module 104 can query geo cell database 111
with search terms 141. Geo cell database 111 can identify any geo
cells having supplemental information that matches search terms
141. For example, if search terms 141 include a street address and
a business name, geo cell database 111 can identify geo cells
having the street name and business name in the area defined by the
geo cell. Geo cell database 111 can return any identified geo cells
to geo determination module 104 in geo cell subset 142.
[0103] Geo determination module can use geo cell subset 142 to
determine the location of event 135 and/or a geo cell associated
with event 135. As depicted, event 135 includes event ID 132, time
133, location 137, description 136, category 137, truthfulness 138,
and severity 139.
[0104] Event detection infrastructure 103 can also determine that
event 135 occurred in an area defined by geo cell 162 (e.g., a
geohash having precision of level 7 or level 9). For example, event
detection infrastructure 103 can determine that location 134 is in
the area defined by geo cell 162. As such, event detection
infrastructure 103 can store event 135 in events 167 (i.e.,
historical events that have occurred in the area defined by geo
cell 162).
[0105] Event detection infrastructure 103 can also send event 135
to event notification module 116. Event notification module 116 can
notify one or more entities about event 135.
[0106] Event Detection And Validation
[0107] FIG. 2 illustrates an example computer architecture 200 that
facilitates detecting an event from features derived from multiple
signals. As depicted, computer architecture 200 further includes
event detection infrastructure 103. Event infrastructure 103 can be
connected to (or be part of) a network with signal ingestion
modules 101. As such, signal ingestion modules 101 and event
detection infrastructure 103 can create and exchange message
related data over the network.
[0108] As depicted, event detection infrastructure 103 further
includes evaluation module 206. Evaluation module 206 is configured
to determine if features of a plurality of normalized signals
collectively indicate an event. Evaluation module 206 can detect
(or not detect) an event based on one or more features (e.g.,
dimensions) of one normalized signal in combination with one or
more features (e.g., dimensions) of another normalized signal.
Features (e.g., dimensions) of normalized signals can be compared
and/or aggregated to derive similarity (or dissimilarity) between
normalized signals, to detect events, and to detect event
changes.
[0109] FIG. 3 illustrates a flow chart of an example method 300 for
detecting an event from features derived from multiple signals.
Method 300 will be described with respect to the components and
data in computer architecture 200.
[0110] Method 300 includes receiving a first signal (301). For
example, event detection infrastructure 103 can receive normalized
signal 122B. Method 300 includes deriving first one or more
features of the first signal (302). For example, event detection
infrastructure 103 can derive features 201 of normalized signal
122B. Features 201 can include and/or be derived from time 123B,
location 124B, context 126B, content 127B, type 128B, and source
129B. Event detection infrastructure 103 can also derive features
201 from one or more single source probabilities assigned to
normalized signal 122B.
[0111] Method 300 includes determining that the first one or more
features do not satisfy conditions to be identified as an event
(303). For example, evaluation module 206 can determine that
features 201 do not satisfy conditions to be identified as an
event. That is, the one or more features of normalized signal 122B
do not alone provide sufficient evidence of an event. In one
aspect, one or more single source probabilities assigned to
normalized signal 122B do not satisfy probability thresholds in
thresholds 226.
[0112] Method 300 includes receiving a second signal (304). For
example, event detection infrastructure 103 can receive normalized
signal 122A. Method 300 includes deriving second one or more
features of the second signal (305). For example, event detection
infrastructure 103 can derive features 202 of normalized signal
122A. Features 202 can include and/or be derived from time 123A,
location 124A, context 126A, content 127A, type 128A, and source
129A. Event detection infrastructure 103 can also derive features
202 from one or more single source probabilities assigned to
normalized signal 122A.
[0113] Method 300 includes aggregating the first one or more
features with the second one or more features into aggregated
features (306). For example, evaluation module 206 can aggregate
features 201 with features 202 into aggregated features 203.
Evaluation module 206 can include an algorithm that defines and
aggregates individual contributions of different signal features
into aggregated features. Aggregating features 201 and 202 can
include aggregating a single source probability assigned to
normalized signal 122B for an event type with a signal source
probability assigned to normalized signal 122A for the event type
into a multisource probability for the event type.
[0114] Method 300 includes detecting an event from the aggregated
features (307). For example, evaluation module 206 can determine
that aggregated features 203 satisfy conditions to be detected as
an event. Evaluation module 206 can detect event 224, such as, for
example, a fire, an accident, a shooting, a protest, etc. based on
satisfaction of the conditions.
[0115] In one aspect, conditions for event identification can be
included in thresholds 226. Conditions can include threshold
probabilities per event type. When a probability exceeds a
threshold probability, evaluation module 106 can detect an event. A
probability can be a single signal probability or a multisource
(aggregated) probability. As such, evaluation module 206 can detect
an event based on a multisource probability exceeding a probability
threshold in thresholds 226.
[0116] FIG. 4 illustrates an example computer architecture 400 that
facilitates detecting an event from features derived from multiple
signals. As depicted, event detection infrastructure 103 further
includes evaluation module 206 and validator 404. Evaluation module
206 is configured to determine if features of a plurality of
normalized signals indicate a possible event. Evaluation module 206
can detect (or not detect) a possible event based on one or more
features (e.g., dimensions) of a normalized signal. Validator 404
is configured to validate (or not validate) a possible event as an
actual event based on one or more features (e.g., dimensions) of
another normalized signal.
[0117] FIG. 5 illustrates a flow chart of an example method 500 for
detecting an event from features derived from multiple signals.
Method 500 will be described with respect to the components and
data in computer architecture 400.
[0118] Method 500 includes receiving a first signal (501). For
example, event detection infrastructure 103 can receive normalized
signal 122B. Method 500 includes deriving first one or more
features of the first signal (502). For example, event detection
infrastructure 103 can derive features 401 of normalized signal
122B. Features 401 can include and/or be derived from time 123B,
location 124B, context 126B, content 127B, type 128B, and source
129B. Event detection infrastructure 103 can also derive features
401 from one or more single source probabilities assigned to
normalized signal 122B.
[0119] Method 500 includes detecting a possible event from the
first one or more features (503). For example, evaluation module
206 can detect possible event 423 from features 401. Based on
features 401, event detection infrastructure 103 can determine that
the evidence in features 401 is not confirming of an event but is
sufficient to warrant further investigation of an event type. In
one aspect, a single source probability assigned to normalized
signal 122B for an event type does not satisfy a probability
threshold for full event detection but does satisfy a probability
threshold for further investigation.
[0120] Method 500 includes receiving a second signal (504). For
example, event detection infrastructure 103 can receive normalized
signal 122A. Method 500 includes deriving second one or more
features of the second signal (505). For example, event detection
infrastructure 103 can derive features 402 of normalized signal
122A. Features 402 can include and/or be derived from time 123A,
location 124A, context 126A, content 127A, type 128A, and source
129A. Event detection infrastructure 103 can also derive features
402 from one or more single source probabilities assigned to
normalized signal 122A.
[0121] Method 500 includes validating the possible event as an
actual event based on the second one or more features (506). For
example, validator 404 can determine that possible event 423 in
combination with features 402 provide sufficient evidence of an
actual event. Validator 404 can validate possible event 423 as
event 424 based on features 402. In one aspect, validator 404
considers a single source probability assigned to normalized signal
122B in view of a single source probability assigned to normalized
signal 122B. Validator 404 determines that the signal source
probabilities, when considered collectively satisfy a probability
threshold for detecting an event.
[0122] In another aspect, validator 404 compares dimensions of
normalized signal 122E to dimensions of normalized signal 122F.
When dimensions are sufficiently similar, validator 404 validates
possible event 423 as event 424.
[0123] Validating Planned Events
[0124] In another aspect, a triggering signal indicates a possible
planned event. The triggering signal may give some indication of
context (e.g., who, what, where, when, how, etc.) around the
planning of the possible planned event. A heuristic process can
also derive context through reference to prior events detected at
or near a location of the possible planned event.
[0125] FIG. 6 illustrates an example computer architecture 600 that
facilitates validating planned events. As described, data ingestion
module(s) 101 can ingest raw signals 121 (e.g., social posts with
geographic content (e.g., location), social posts without
geographic content, traffic camera feeds, 911 calls, weather data,
planned events, IoT device data, crowd sourced traffic and road
information (e.g., Waze data), etc.). Data ingestion module(s) 101
can normalize raw signals 121 into normalized signals 122,
including normalized signals 122G and 122H. Data ingestion
module(s) 101 can send corresponding normalized signals 122 to
event detection infrastructure 103.
[0126] Event detection infrastructure 103 can receive a plurality
of normalized signals 122 from data ingestion module(s) 101. Event
detection infrastructure 103 can route one or more normalized
signals to evaluation module 606 (which can include functionality
similar to evaluation module 206). For each normalized signal 122,
evaluation module 306 can determine (e.g., by considering Time,
Location, and Context dimensions) if one or more normalized signals
possibly indicate a planned event. Classifiers 607 can include a
classifier for each of multiple event categories, such as, for
example, concert, protest, sporting event, etc. Evaluation module
606 can invoke a classifier 607 for each event category to
determine if one or more normalized signals (either alone or
collectively) satisfy specified requirements indicative of a
possible planned event. When one or more normalized signals 122
(either alone or collectively) satisfy specified requirements of a
classifier 607, the one or more normalized signals 122 are
considered to indicate a possible planned event in the
corresponding category.
[0127] In one aspect, event detection infrastructure 103 includes a
signal scorer (not shown). The signal scorer can generate a score
indicating the likelihood of a normalized signal indicating a
possible event. Per normalized signal, the signal scorer can send
the normalized signal and corresponding score to evaluation module
606. For each classifier 607, evaluation module 606 can determine
if an individual score for a normalized signal or an aggregate
score for a plurality of normalized signals (e.g., computed by
aggregating one or more of Time, Location, and Context dimensions)
satisfy a threshold.
[0128] Event detection infrastructure 103 can also route one or
more normalized signals and detected possible planned events to
validator 604 (which can include functionality similar to validator
404). Validator 604 can attempt to validate a possible planned
event as an actual planned event in a specified event category
based on characteristics (e.g., dimensions) of one or more
normalized signals. In one aspect, evaluation module 606 detects a
possible planned event based on characteristics (e.g., dimensions)
of a first normalized signal. Validator 602 can perform one or more
searches on content in a second normalized signal (e.g., names,
keywords, places, etc.) and with a time at or near the time of the
first normalized signal (e.g., computed from Time dimension
comparison). Data returned from the one or more searches can be
used to validate a possible planned event.
[0129] Evaluation module 606 and/or validator 604 can also derive
(e.g., using artificial intelligence and/or machine learning) a
location of a possible planned event from content of the first
normalized signal and/or the second normalized signal (e.g., from
Location dimensions). Event history 614 database (possibly included
in geo cell database 111) can store a history of prior events
detected at one or more locations (e.g., in areas bounded by one or
more geo cells). Validator 604 can query event history database 614
for events at a specified location. Event history database 614 can
return event history for the specified location to validator
604.
[0130] Validator 604 can use content (including dimensions) from
one or more of: the first normalized signal, the second normalized
signal, and returned event history to formulate an event context.
From the event context, validator 604 can identify a (e.g.,
authoritative) planning system. that is potentially associated with
the planned event. Validator 604 can query the planning system with
the formulated event context.
[0131] In one aspect, there may be multiple different planning
systems that plan different events. Validator 604 can query any
number of the plurality of planning systems until an authoritative
planning system is identified. For example, one or more additional
planning systems in addition to planning system 611 can be included
in computer architecture 600.
[0132] The planning system can attempt to identify an event
associated with the formulated context that the planning system was
involved in planning The planning system can return validating data
to validator 604. Validator 604 can use the validating data to
validate a possible planned event as an actual planned event.
[0133] It may also be that validator 604 does not validate a
possible event as an actual event. For example, there may be no
event history for a location, a planning system may not return
validating data, etc.
[0134] FIG. 7 illustrates a flow chart of an example method 700 for
validating a planned event. Method 700 will be described with
respect to the components and data depicted in computer
architecture 600.
[0135] As normalized signals are received at event detection
infrastructure 103, the normalized signals can be routed to
evaluation module 606 and/or routed to validator 604. For example,
normalized signal 122G can be routed to evaluation module 606 and
validator 604. Normalized signal 1223H can be routed to validator
604.
[0136] Method 700 includes receiving a normalized signal (701). For
example, evaluation module 606 can receive normalized signal 122G.
Method 700 includes detecting a possible planned event in an event
category based on characteristics of the normalized signal (702).
For example, a classifier 607 can detect possible planned event 623
in an event category (e.g., concert, protest, sporting event, etc.)
based on characteristics (e.g., dimensions) of (or a computed score
corresponding to) normalized signal 122G. Evaluation module 606 can
send possible planned event 623 to validator 604.
[0137] Method 700 includes deriving a location of the possible
planned event (703). For example, validator 604 (e.g., using
artificial intelligence and/or machine learning) can derive
location 616 of possible planned event 623 from the characteristics
of normalized signal 122G, 122GH, etc. Validator 604 can also
determine (e.g., through similarity in one or more of a Time
dimension, a Location dimension, or a Context dimension) that
normalized signal 122H is related to possible planned event 623.
Validator 604 can derive location 616 from characteristics (e.g., a
Location dimension) of normalized signal 122G and any related
normalized signals, such as, normalized signal 122H.
[0138] Method 700 includes accessing an event history of one or
more prior events at the location (704). For example, validator 604
can query event history database 614 with location 616. Event
history database 614 can return event history 617 to validator 604.
Event history 617 can indicate prior events that occurred at (or
within) location 616. Method 700 includes deriving an event context
from the characteristics of the normalized signal and the contents
of the event history (705). For example, validator 604 can derive
event context 612 (circumstances surrounding possible planned event
623) from the characteristics (e.g., dimensions) of normalized
signal 122G (also possibly characteristics, for example,
dimensions, of normalized signal 122H) and event history 617.
[0139] Method 700 includes submitting the event context to a
planning system potentially associated with a planned event at the
location (706). For example, validator 604 can determine that
planning system 611 may have participated in the planning of an
event at location 616. Validator 604 can submit event context 612
to planning system 611. Planning system 611 can determine if it
planned an event having event context 612. For example, planning
system 611 can determine that event context 612 is associated with
planned event 624 and that planning system 611 was involved in
planning planned event 624. As such, planning system 611 can
formulate validating data 613 and can send validating data 613 to
validator 604.
[0140] On the other hand, planning system 611 can determine that it
did not participate in the planning of an event having event
context 612. As such, planning system 611 indicates to validator
604 that it did not participate in the planning of possible planned
event 623. In response, validator 604 can submit event context 612
to one or more other planning systems. Validator 604 can continue
submitting event context 612 to other planning systems until a
planning system sends validating data to validator 604.
[0141] Validator 604 may also have submitted event context 612 to
one or more other planning systems prior to submitting event
context 612 to planning system 611. Thus, validator 604 can query
one or more other planning systems before and/or after querying
planning system 611.
[0142] Method 700 includes receiving validating data from the
planning system (707). For example, validator 604 can receive
validating data 613 from planning system 611. Alternately,
validator 604 can receive an indication from planning system 611
that it did not participate in the planning of possible planned
event 623. Method 700 includes validating the possible planned
event as the planned event from the validating data (708). For
example, validator 604 can validate possible planned event 623 as
(actual) planned event 624 based on validating data 613.
[0143] In one aspect, if planning system 611 does not return
validating data, validator 604 sends event context 612 to another
planning system. The other planning system can return validating
data or can indicate it did not participate in planning of possible
planned event 623. Validator 604 may send event context 612 to a
specified number of planning systems prior to determining that
possible planned event 623 is not validated.
[0144] Validator 604 may also continue to query additional planning
systems even after validating data is received from a planning
system. Validator 604 can compare validating data from multiple
different planning systems. When validating data from different
planning systems is consistent, validator 604 further validates a
possible planned event as a planned event. When inconsistencies in
validating data are identified, validator 604 can resolve
inconsistencies by giving preference to validating data from
particular planning systems that are more relevant. For example,
for a hockey game, validator 604 can give preference to validating
data from a hockey league website over validating data from a
secondary ticket sales website. The league website may give a game
start time while ticket sales website indicates start time as the
time parking is open (which could be many hours before the game
starts).
[0145] Validating Planned Event Information And Changes
[0146] In a further aspect, planned event information is received
from multiple different sources. The planned event information and
can be validated and discrepancies reconciled. FIG. 8 illustrates
can example computer architecture 800 that facilitates detecting
and validating planned event information.
[0147] As depicted in computer architecture 800, signal ingestion
modules 101 can include extractor 813 and Application Programming
Interface (API) 814. Extractor 813 and/or API 814 are configured to
ingest raw signals from "Events" websites 172A (which are
potentially included in Web signals 172). Extractor 813 can be more
specifically configured to extract information from an Internet
site that has been made available for general consumption. Raw
signals ingested from "Events" websites 172A can include
information related to planned events. Signal ingestion modules 101
can normalize raw signals including planned event related
information into corresponding normalized signals and send the
normalized signals to event detection infrastructure 103.
[0148] As depicted, event detection infrastructure 103 includes
planned event detector 864. Planned event detector 864 which can
interoperate with other modules of event detection infrastructure
103 to detect and characterize planned events and changes to
planned events. Planned event detector 864 can include (e.g.,
machine learning, artificial intelligence, neural networks, etc.)
modules that facilitate automated detection and validation of
planned events and changes to planned events. The modules of
planned event detector 864 can determine when multiple normalized
signals are associated with the same planned event. The modules of
planned event detector 864 can also determine when information
(e.g., dimensions) in normalized signals concurs or disagrees with
respect to the details (e.g., title, description, location, time,
etc.) of a planned event.
[0149] In one aspect, modules of planned event detector 864
determine that different normalized signals concur with respect to
details of planned event information. When different normalized
signals concur, planned event detector 864 can validate a planned
event. For example, planned event detector 864 can compare
characteristics (including dimensions) of different normalized
signals to one another. When the characteristics are sufficiently
similar, planned event detector 864 determines that the normalized
signals concur.
[0150] In another aspect, modules of planned event detector 864
determine that information in different normalized signals is
inconsistent (e.g., by comparison). In response, the modules of
planned event detector 864 derive search terms from information
(e.g., dimensions) contained in the normalized signals. Event
detection infrastructure 103 can query geo cell database 111 with
the search terms. Geo cell database 111 can determine that the
search terms match the contents of one or more geo cell entries.
Geo cell database 111 can return a geo cell subset, including any
matching geo cells, to event detection infrastructure 103.
[0151] Venue database 816 stores geo cell to venue mappings
indicating venues included in a geo cell. For example, venue
database 816 indicates that venue 192A is contained in an area
defined by geo cell 191A, venue 192B is contained in area defined
by geo cell 191B, etc. Event detection infrastructure 103 can query
venue database 816 with geo cells contained in a geo cell subset.
Venue database 816 can determine that a geo cell contained in a geo
cell subset matches a geo cell corresponding to a venue. Venue
database 816 can return a matching geo cell and corresponding venue
to event detection infrastructure 103. Modules of planned event
detector 864 can use the corresponding venue as the location of a
planned event.
[0152] Modules of planned event detector 164 can query geo cell
database 111 and venue database 816 to disambiguate between the
same venue named differently (e.g., nicknames, official names,
foreign language names, etc.). Modules of planned event detector
164 can also query geo cell database 111 and venue database 816 to
account for changed venues, for example, venues closing, being
renamed, and new venues opening.
[0153] Modules of planned event detector 164 can resolve other
inconsistencies (e.g., using machine learning, artificial
intelligence, neural networks, etc.), if any remain, in an
automated fashion through reference to other databases.
Inconsistencies unresolvable in an automated fashion can be forward
to other resolution systems.
[0154] In one aspect, event detection infrastructure 103 draws a
polygon on a map to indicate a venue location.
[0155] The resolution of geo cells in geo cell database 111 and
venue database 194 can be sufficiently precise (e.g., geo hash
level 7 or 8) so that similar venues side by side on the same block
(e.g., different theaters) can be distinguished.
[0156] FIG. 9 illustrates a flow chart of an example method 900 for
detecting and validating planned event information. Method 900 will
be described with respect to the components and data depicted in
computer architecture 800.
[0157] Method 900 includes acquiring first planned event data from
a first website, the first planned event data including a first
date, a first start time, a first end time, and a first location
(901). For example, extractor 813 and/or API 814 can acquire raw
signal 1211 from "Event" websites 172A. Signal ingestion modules
101 can normalize raw signal 1211 into normalized signal 122I.
Normalized signal 122I can include date 846, start time 847, and
end time 848 (e.g., in a Time dimension) and location 849 (e.g., in
a Location dimension) of a planned event.
[0158] Method 900 includes acquiring second planned event data from
a second web site, the second planned event data including a second
date, a second start time, a second end time, and a second location
(902). For example, extractor 813 and/or API 814 can acquire raw
signal 121J from "Event" websites 172A. Signal ingestion modules
101 can normalize raw signal 121J into normalized signal 122J.
Normalized signal 122J can include date 856, start time 857, and
end time 858 (e.g., in a Time dimension) and location 859 (e.g., in
a Location dimension) of a planned event.
[0159] Method 900 includes determining if the first planned event
data and the second planned event data concur with respect to
details of a planned event (903). For example, planned event
detector 864 can determine if planned event data in normalized
signal 122I is consistent with planned event data in normalized
signal 122J. That is, does date 846 concur with date 856, does
start time 847 concur with state time 857, does end time 848 concur
with end time 858, does location 849 concur with location 859,
etc.? In one aspect, Time dimensions and/or Location dimensions of
normalized signals 1221 and 122J are compared. When sufficient
similarity is detected, the signals are determined to concur.
[0160] When the first planned event data and the second planned
event data do concur with respect to details of a planned event
(YES at 903), method 900 includes notifying at least one entity of
the planned event (or planned event change) (906). For example,
planned event detector 864 can determine that date 846 does concur
with date 856, start time 847 does concur with state time 857, does
end time 848 does concur with end time 858, location 849 does
concur with location 859, etc. Planned event detector 864 can
detect event planned event 893 (or change to planned event 893)
from normalized signals 1221, 122J, etc. (e.g., using mechanisms
described with respect to computer architecture 600 and method
700). Event detection infrastructure 864 can send planned event 893
(or a change to planned event 893) to event notification 116.
[0161] When the first planned event data and the second planned
event data do not concur with respect to details of a planned event
(NO at 903), method 900 includes identifying an inconsistency
between at least one of: the first date and the second date, the
first start time and the second start time, the first end time and
the second end time, or the first location and the second location
(904). For example, planned event detector 864 can detect an
inconsistency between one or of: dates 846 and 856, start times 847
and 857, end times 848 and 858, locations 849 and 859, etc. (e.g.,
through comparison of Time and/or Location dimensions).
[0162] Method 900 includes automatically resolving the
inconsistency into consistent details of a planned event (905). For
example, planned event detector 864 can automatically resolve
inconsistencies in one or of: dates 846 and 856, start times 847
and 857, end times 848 and 858, locations 849 and 859, etc. into
consistent details of a planned event. In one aspect, planned event
detector 864 derives search terms 894 from the characteristics of
normalized signals 1221, 122J, etc. (e.g., from phrases such as
"112 Main St.", "at the corner of Elm and South Parkway", "in front
of Oracle Arena"). Event detection infrastructure 103 queries geo
cell database 111 with search terms 194. Geo cell database 111 can
determine that search terms 894 match the contents of one or more
geo cell entries. Geo cell database 111 can return one or more
matching geo cells, including geo cell 152, to event detection
infrastructure 103 in geo cell subset 896.
[0163] Event detection infrastructure can query venue database 816
with geo cell 152. Venue database can determine that geo cell 152
matches geo cell 891A. As such, venue database 816 can return venue
892A to event detection infrastructure 103. Planned event detector
864 can use venue 892A as a resolved location for planned event
893, addressing any inconsistency between locations 849 and
859.
[0164] Method 900 then includes notifying at least one entity of
the details of the planned event (906). For example, event
detection infrastructure can send planned event 893 (or a change to
planned event 893) to event notification 116.
[0165] Modules of planned event detector 164 can resolve other
inconsistencies, if any remain (e.g., between dates 846 and 856,
between start times 847 and 857, between end times 848 and 858,
etc.), in an automated fashion through reference to geo cell
database 111 and other databases. Inconsistencies unresolvable in
an automated fashion can be forwarded to other resolution
systems.
[0166] Accordingly, an initial check for planned event data
inconsistencies can be performed to determine if further planned
event data resolution is appropriate. Planned event data resolution
is performed when inconsistencies are detected. On the other hand,
planned event data resolution data can be skipped when planned
event data in different signals concurs with one another. Thus, an
initial lower resource intensive inconsistency check can be
performed to determine if more resource intensive data resolution
is appropriate.
[0167] Validating Planned Event Occurrence and Auto Curating
Content
[0168] FIG. 10 illustrates an example computer architecture 1000
that facilitates validating occurrence of a planned event and auto
curating content. As depicted, computer architecture 1000 includes
validation and curation system 1001. Validation and curation system
1001 further includes image classifier 1002, text classifier 1003,
selfie classifier 1004, and logo classifier 1006. In response to
receiving an indication of a planned event, validation and curation
system 1001 can form a polygon listening area around the location
of the planned event some amount of time prior to the start time of
the planned event. The polygon listening area can represent a
geographic area at and around a planned event venue. A polygon
listening area can be virtually any shape (square, rectangle,
circle, oval, etc.) or any a series of connected line segments
representing a closed area.
[0169] Validation and curation system 1001 can listen for signals
in the polygon listening area Image classification 1002 and text
classification 1003 an process signals from the polygon listening
area to determine if the signals are related to the planned event.
When sufficient signal volume related to a planned event occurs in
a polygon listening area within a specified time period, validation
and curation system 1001 validates that the planned event is
occurring. On the other hand, when insufficient signal volume
related to a planned event is detected in a polygon listening area
within a specified time period, validation and curation system 1001
determines that a planned event is not occurring.
[0170] When a planned event is validated, validation and curation
system 1001 can continue to listen for signals in the polygon
listening area. Signals can stream to validation and curation
system during the planned event (e.g., during sporting event,
convert, etc.). Image classifier 1002, text classifier 1003, selfie
classifier 1004, and logo classifier 1006 can interoperate to auto
curate a set of higher quality content (videos, images, text.
etc.). The higher quality content can be broadcast worthy and tell
a "good story" about the planned event. The higher quality content
can be delivered to media customers (e.g., Television stations) for
possible "on air" broadcasts. On the other hand, image classifier
1002, text classifier 1003, selfie classifier 1004, and logo
classifier 1006 filter out lower quality content that is not
delivered to media customers.
[0171] In one aspect, validation and curation system 1001 receives
planned event 1011, including location 1012, start time 1013, and
categories 1014. Validation and curation system 1001 forms polygon
listening area 1017 around location 1012 some amount of time prior
to start time 1013. Validation and curation system 1001 listens for
signals in polygon listening area 1017 for a specified time period
after formation. Validation and curation system 1001 can detect
signals 1016 within the specified time period.
[0172] Validation and curation system 1001 can derive planned event
status 1018 of planned event 1011 based on signals 1016. In one
aspect, signals 1016 include a sufficient volume of signals related
to planned event 1011 (e.g., to categories 1014). In response,
validation and curation system 1001 validates planned event 1011
and continues to listen for signals in polygon listening area 1017.
Validation and curation system 1001 indicates in planned event
status 1018 that planned event 1011 is validated. In another
aspect, signals 1016 include an insufficient volume of signals
related to planned event 1011 (e.g., to categories 1014). In
response, validation and curation system 1001 determines that
planned event 1011 is not occurring and ceases listening for
signals in polygon listening area 1017. Validation and curation
system 1001 indicates in planned event status 1018 that planned
event 1011 did not occur.
[0173] During planned event 1011, signals 1021 can stream to
validation and curation system 1001. Image classifier 1002, text
classifier 1003, selfie classifier 1004, and logo classifier 1006
can interoperate to auto curate content 1019 from signals 1021.
Auto curated content 1019 can be broadcast worthy and tell a "good
story" about planned event 1011.
[0174] Automating Planned Events Via A Human-Artificial
Intelligence Feedback Loop
[0175] Some categories of planned events can be partially or fully
automated. Automation can range from requiring fully human review
to completely bypassing human review. A feedback loop permits a
planned event detection system (e.g., integrated into event
detection system 103) to learn from the decisions of automated
reviewers and improve on its own. Depending on source and category
of events, planned events can be fully automated, partially
automated, or not automated. Sources and categories of planned
events that are partially or fully automated can be audited on a
periodic basis to insure accurate detections.
[0176] In one aspect, the mechanisms of computer architecture 800
and method 900 interoperate with the mechanisms of computer
architecture 600 and method 700. A planned event detector can
determine planned event data concurs across a plurality of
normalized signals and/or can resolve any planned event data
inconsistencies in an automated fashion. Evaluation module 606
and/or validator 604 can detect a planned event from concurring
and/or resolved planned event data.
[0177] A unified interface included in signal ingestion modules 101
can handle incoming signals and content of any kind. The interface
can handle live extraction of signals across dimensions of Time,
Location, and Context. In some aspects, heuristic processes are
used to determine one or more dimensions. Acquired signals can
include text and images as well as live-feed binaries, including
live media in audio, speech, fast still frames, video streams,
etc.
[0178] Signal normalization enables the world's live signals to be
collected at scale and analyzed for detection and validation of
changes to planned events happening globally. A data ingestion and
event detection pipeline aggregates signals and combines detections
of various strengths into truthful events. Thus, normalization
increases event detection efficiency facilitating event change
detection closer to "live time" or at "moment zero".
[0179] The present described aspects may be implemented in other
specific forms without departing from its spirit or essential
characteristics. The described aspects are to be considered in all
respects only as illustrative and not restrictive. The scope is,
therefore, indicated by the appended claims rather than by the
foregoing description. All changes which come within the meaning
and range of equivalency of the claims are to be embraced within
their scope.
