Description
FIELD OF THE INVENTION
[0001] The present invention relates to the field of Internet
applications. In particular, the present invention relates to a
method and system for entering search queries.
BACKGROUND OF THE INVENTION
[0002] In recent years, the Internet has been a main source of
information for millions of users. These users rely on the Internet
to receive their news, and to search for information of their
interest. One conventional way for users to search for additional
information after reading a news story or other information on a
webpage is to conduct a search through a search box supported by a
search engine. To do so, a user would have to determine what
keywords to enter into the search box based on the understanding of
the particular news story or information being read. In addition,
the user would have to physically type the keywords in the search
box. In other words, the conventional method puts the burden of
determining the search queries on the user, such as analyzing the
information and deriving relevant search queries from the
information being viewed.
[0003] Therefore, there is a need to alleviate the user from
analyzing and deriving search queries and there is a need to
alleviate the user from physically typing the search terms.
SUMMARY
[0004] In one embodiment, a method for entering search queries
includes presenting a web page, wherein the web page includes at
least a story and a thumbnail image associated with the story,
dragging the thumbnail image to a search box on the web page,
releasing the thumbnail image to the search box, and populating the
search box with keywords associated with the thumbnail image.
[0005] In another embodiment, an apparatus for entering search
queries, where the apparatus includes logic operable on a computer
server, includes logic for presenting a web page, wherein the web
page includes at least a story and a thumbnail image associated
with the story, logic for dragging the thumbnail image to a search
box on the web page, logic for releasing the thumbnail image to the
search box, and logic for populating the search box with keywords
associated with the thumbnail image.

DESCRIPTION OF EMBODIMENTS
[0012] Methods and systems are provided for entering search
queries. The following descriptions are presented to enable any
person skilled in the art to make and use the invention.
Descriptions of specific embodiments and applications are provided
only as examples. Various modifications and combinations of the
examples described herein will be readily apparent to those skilled
in the art, and the general principles defined herein may be
applied to other examples and applications without departing from
the spirit and scope of the invention. Thus, the present invention
is not intended to be limited to the examples described and shown,
but is to be accorded the widest scope consistent with the
principles and features disclosed herein.
[0013] Some portions of the detailed description that follows are
presented in terms of flowcharts, logic blocks, and other symbolic
representations of operations on information that can be performed
on a computer system. A procedure, computer-executed step, logic
block, process, etc., is here conceived to be a self-consistent
sequence of one or more steps or instructions leading to a desired
result. The steps are those utilizing physical manipulations of
physical quantities. These quantities can take the form of
electrical, magnetic, or radio signals capable of being stored,
transferred, combined, compared, and otherwise manipulated in a
computer system. These signals may be referred to at times as bits,
values, elements, symbols, characters, terms, numbers, or the like.
Each step may be performed by hardware, software, firmware, or
combinations thereof.
[0014] FIG. 1 illustrates a system for running news applications on
a website according to an embodiment of the present invention. The
system includes one or more Internet content provider servers 102,
databases 105, and one or more clients 104. The servers 102
interface with the clients 104 via a communication network 103. The
Internet content provider servers 102 are host servers operable to
provide content to clients 104 via the network 103. One or more of
the servers host web sites and include the news and search
functions. The databases 105 are operable to store data provided by
the servers 102 and/or clients 104. The databases can communicate
with the servers 102 or clients 104 via the network 103. The
databases can store data items included in the web pages, such as
news pages.
[0015] Alternatively, the servers 102 may include the databases,
processors, switches, routers, interfaces, and other components and
modules. Each of the servers 102 may comprise one or more servers,
or may be combined into a lesser number of servers than shown,
depending on computational and/or distributed computing
requirements. The servers 102 may be located at different locations
relative to each other. The databases may also be separately
connected to the servers 102. There may be more or less than two
databases, depending on computational and/or distributed computing
requirements. The databases may be located at different locations
relative to each other and the servers 102.
[0016] Each of the clients 104 may be a general purpose computer,
such as a personal computer, having a central processing unit
(CPU), a memory, an input device, and an output device. Other
computer system configurations, including Internet appliances,
hand-held devices, wireless devices, portable devices, wearable
computers, cellular or mobile phones, portable digital assistants
(PDAs), multi-processor systems, microprocessor-based or
programmable consumer electronics, set-top boxes, network PCs,
mini-computers, and the like may also be implemented as the clients
104. Clients 104 include one or more applications, program modules,
and/or sub-routines. As an example, clients 106 may include a
browser application (e.g., Internet Explorer, etc.) and a graphical
user interface (GUI) to access web sites and web pages provided by
the servers 102 and data stored at the databases 105. Clients 104
may be remote from each other, the servers 102, and/or the
databases.
[0017] The network 103 is a communications network, such as a local
area network (LAN), a wide area network (WAN), or the Internet.
When the network 103 is a public network, security features (e.g.,
VPN/SSL secure transport) may be included to ensure authorized
access within the system.
[0018] The servers 102 further include a plurality of individual
domains, for example, shopping domain 106, news domain 108, photos
domain 110 and other domains 112. A domain is a computer system
implemented with different hardware and software for a specific
application, such as the shopping applications, news applications,
and photo applications. The news applications of the present
invention are run on the news domain 108. These applications
implement Web 2.0 functionalities using a combination of HTML, CSS,
JavaScript and "Asynchronous JavaScript and XML" (AJAX).
[0019] In particular, JavaScript is used to create, monitor, change
objects and change the state of various image objects, in addition
to keeping track of browser behavior changes initiated by the user.
For example, when a user starts dragging an original thumbnail
image in the browser window, the browser fires "mouse down" and
"mouse move" events which are captured by the JavaScript and an
object is created to handle the event. The object is effectively a
copy of the original thumbnail image, and the copy of the image is
being moved around. In other words, each object has states, and
such states are created and modified in response to user initiated
changes (events) to the browser behavior.
[0020] As described above, the process of monitoring and updating
states of an object is event driven. When a user performs a
specific action, JavaScript that runs in the background determines
the exact browser event that has been initiated according to a set
of user cases. For example, if the user clicks outside of an image
and drags, that action is interpreted as the intent to draw a
selection rectangle. Similarly, if the user clicks directly on an
image and starts to move by a distance greater than five pixels,
that action is interpreted as a drag. Then, the JavaScript starts
to monitor the mouse movement and attaches the thumbnail images to
the cursor at that point. While moving the cursor, the JavaScript
updates the attached image's position and waits for the user to
release the image. Upon the image being released, the JavaScript
determines the location of the cursor within the browser window. If
the image is dropped on the search box, the keywords associated
with the image are appended to the list of keywords already exist
in the search box. If the image is dropped on an invalid drop
target, a reset action is initiated and the image is snapped back
to its original location. While the user is dragging a thumbnail
image, the JavaScript monitors where the cursor is, and determines
whether it is over a valid drop target or an invalid drop target.
In the case that the cursor is over a valid drop target, the
JavaScript would cause the valid drop target to be highlighted,
providing a positive feedback to the user. When the cursor moves
out of the valid drop target, the JavaScript would deactivate the
highlighted area.
[0021] FIG. 2 illustrates a news page for applying the drag and
drop search method according to an embodiment of the present
invention. As shown in the left column of FIG. 2, the news page
includes a main story and a series of other stories.
[0022] Each story includes a headline 202, a textual summary 204,
and an thumbnail image 206 (also referred to as an image object) of
the story. The News page further includes a series of related
photos and videos 208 of the main story. In addition, the News page
also includes a search box 210 which users may enter one or more
key words and then press the search button 212 to search for
additional information related to their interest. In the right
column, the news page includes various classifications of news,
such as the US news, business, world news, entertainment, sports,
technology, politics, science, health, and other topics of
interest. After reading this news page, a user may be interested in
a particular image object and may like to search for more
information about the image object. The present disclosure enables
a user to perform a drag-and-drop operation on an image object of
interest to the search box.
[0023] FIG. 3 illustrates a representation of an image object being
dragged according to an embodiment of the present invention. In
this example, the user is interested in the "Alaska gas pipeline
talks" story and elects to drag the image object of this story to
the search box for further search. As shown in FIG. 3, a copy of
the image object 302 of this article is being dragged to the search
box. In one implementation, keywords are assigned to the image
object that describes the image and the association to the related
article through the <keyword> tag. In this case, a set of
keywords 304 are attached to the corresponding image object in
transit, which include "pipeline", "Alaska", "North Slope", and
"oil producers."
[0024] Note that a visual indicator, such as an icon, may be
applied to a draggable image object to inform the user of the
search capabilities (i.e. drag-and-drop functionalities) that may
be applied to the image object. Once the image object 302 is being
dragged, another visual indicator may be attached to the image
object displaying the actual keywords 304 associated with that
image, and while in the "dragging" state, yet another visual
indicator, such as highlight color, may be assigned to the drop
target(s) available to receive the dragged image object. In this
example, the drop target is the search box 306.
[0025] FIG. 4 illustrates a representation of the image object of
FIG. 3 prior to release to a drop target according to an embodiment
of the present invention. In FIG. 4, the image object 402 and its
corresponding keywords 404 are dragged to the top of the search box
406. The search box continues to be highlighted indicating it is a
valid drop target. FIG. 5 illustrates a representation of the image
of FIG. 3 after being released to the drop target according to an
embodiment of the present invention. Upon release of the image
object on the drop target, which is the search box 502 in this
example, the associated keywords of the image object are
auto-populated in the search box. Then the highlight color around
the search box is removed. From the auto-populated list of
keywords, the user may start a search based on these search terms.
Alternatively, the user may edit the list of keywords and then
initiate a search of the revised search terms in the search
box.
[0026] Note that the search terms are auto-populated and the user
is alleviated from having to physically type in the search terms.
Therefore, from a user experience point of view, the disclosed
method provides users the ability to search an image object that
they are interested in. It also alleviates the user from
determining what search terms that should go into the search
box.
[0027] In one approach, the information in the news page is modeled
after the Rich Site Summary (RSS) format. The following is an
example of a news page in RSS format:

<rating>4</rating> <keywords>Floodwater, Health
Risks, New Orleans, Scientists, Safe</keywords>
</story>
[0028] As shown above, each story is described within the
<story> and </story> tags of the RSS data. In this
example, the RSS format of the story further includes the following
tags. In other embodiments, some of the tags may not be used and
some other tags may be added. [0029] <title>: describes the
title of the story; [0030] <ogsource>: describes the source
of the news story, such as CNN; [0031] <age>: describes when
the news story was published, such as 12 minutes ago in the first
story; [0032] <comments>: indicates how many user comments
were posted about this story; [0033] <thumburl>: indicates
the source (URL) location of the thumbnail image object, such as
data/img/thumb27.jpg; [0034] <description>: describes a
summary or the full content of the story; [0035] <rating>:
indicates a rating of the story; and [0036] <keywords>:
describes a list of keywords related to the story.
[0037] When a user drags an image object, the application software
examines the RSS data to determine where the thumbnail URL tag and
the keyword tag. The thumbnail URL provides information for
locating the image object resource. In the example above, the path
to the corresponding image object thumb27.jpeg is located in a
folder called img, which is in a folder called data.
[0038] In one implementation, the Macromedia Flash is used as
platform of development. In particular, the RSS data feed is
implemented as a Macromedia Flash Plug-In. RSS is a family of XML
dialects for web syndication used by news websites and weblogs. The
technology of RSS allows Internet users to subscribe to websites
that have provided RSS feeds, which are typically websites that
change or add content regularly. To use this technology, site
owners create or obtain specialized software (such as a content
management system) that, in the machine-readable XML format,
presents new articles in a list, and provides a line or two of each
article and a link to the full article.
[0039] The RSS formats provide web content or summaries of web
content with links to the full versions of the content and other
meta-data. This information is delivered as an XML file called an
RSS feed, web-feed, RSS stream, or RSS channel. In addition to
facilitating syndication, RSS allows a website's frequent readers
to track updates on the site using an aggregator.
[0040] RSS may also be used by the weblog community to share the
latest entries of headline news and their corresponding full text,
and attached multimedia files to the news, such as podcasting,
vodcasting, broadcasting, screencasting, Vloging, and MP3 blogs.
The use of RSS has been adopted by certain news organizations,
including Reuters, CNN, and the BBC. These news providers allow
other websites to incorporate their "syndicated" headlines or
headlines and short summary feeds under various usage arrangements.
RSS may also be used for other purposes, including any other
activities that involve periodic updates or publications.
[0041] In one approach, a program known as a feed reader or
aggregator can check RSS-enabled web pages on behalf of a user and
display any updated articles that it finds. RSS feeds may be found
on major and smaller websites, as well as on Blog sites.
[0042] Client-side readers and aggregators are typically
constructed as standalone programs or extensions to existing
programs like web browsers. Browsers are moving toward integrated
feed reader functions, for example Opera and Mozilla Firefox. Such
programs are available for various operating systems. Web-based
feed readers and news aggregators require no software installation
and make the user's feeds available on any computer with Web
access. Some aggregators combine RSS feeds into new feeds, for
example taking all football-related items from several sports feeds
to provide a new football feed. There are also search engines for
content published via RSS feeds like Feedster or Blogdigger. On web
pages, RSS feeds are typically linked with the letters XML or
RSS.
[0043] In another embodiment, multiple image objects may be dragged
to the search box and their corresponding keywords are appended to
form a query search string. The user may edit the query search
string to add terms the user is interested in or remove terms the
user is not interested in. Once the search box is auto-populated
with keywords from the multiple image objects, the user may search
the Internet for information about the image objects, and the
search results are returned and presented on the web page. Note
that the disclosed method may expand or create new tags in the RSS
data that would be specific to the drag-and-drop search function.
For example, a <keyword> tag that applies to the image only
or <association> or <context> tag that relates the
image object to the context of the story in which it is associated
with.
[0044] Yet in another embodiment, the drag-and-drop function may be
utilized in a photo album scenario where the album name may be
auto-populated according to its contents. In addition, the photo
album may be defined and auto-populated with image objects.
[0045] It will be appreciated that the above description for
clarity has described embodiments of the invention with reference
to different functional units and processors. However, it will be
apparent that any suitable distribution of functionality between
different functional units or processors may be used without
detracting from the invention. For example, functionality
illustrated to be performed by separate processors or controllers
may be performed by the same processor or controllers. Hence,
references to specific functional units are to be seen as
references to suitable means for providing the described
functionality rather than indicative of a strict logical or
physical structure or organization.
[0046] The invention can be implemented in any suitable form
including hardware, software, firmware, or any combination of
these. The invention may optionally be implemented partly as
computer software running on one or more data processors and/or
digital signal processors. The elements and components of an
embodiment of the invention may be physically, functionally and
logically implemented in any suitable way. Indeed the functionality
may be implemented in a single unit, in a plurality of units, or as
part of other functional units. As such, the invention may be
implemented in a single unit or may be physically and functionally
distributed between different units and processors.
