METHOD AND SYSTEM FOR PROVIDING ANNOTATIONS OF A DIGITAL WORK
Abstract
Methods and systems for receiving and distributing annotations
of a digital work include receiving an annotation of the digital
work, storing the annotation, and providing the annotation to a
user. The user may be required to submit a valid authorization
credential for the annotation. Annotations may be textual or
graphical, and may be associated with particular content in a
digital work. Indicators may be displayed to identify content in
the digital work for which annotations are available. A user may
exchange compensation or perform a specified action for access to
an annotation. Some or all of the compensation received for an
annotation may be distributed to the author of the annotation.
Multiple annotations may be listed in an order based a criterion,
such as ranking, price, or date of receipt. Users that purchase a
digital work may automatically receive an authorization credential
to receive annotations of the digital work.

Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application is a continuation of U.S. patent
application Ser. No. 11/039,645, filed Jan. 19, 2005, the entire
disclosure of which is hereby incorporated by reference herein.
FIELD OF THE INVENTION
[0002] The present invention relates to distribution of digital
works, and more particularly to creating a market for distribution
of annotations of digital works.
BACKGROUND OF THE INVENTION
[0003] For many years, print media provided the only way to
transmit information and ideas in a fixed form. With the advent of
photography and audio recording, additional media have become
available for transmitting information and ideas. The information
in such media, however, is static. Updated information is provided
only by preparing and distributing additional media. However,
widespread distribution of updated information, including comments,
supplements, features, thoughts, insights, etc., becomes difficult
when the information is authored by multiple parties. Media
consumers having additional information or insight typically do not
have a way to effectively share that information with other
consumers. What is needed is a method and system that allows users
of media to easily annotate the media and afterward distribute such
annotations to others in an economical and efficient manner. The
present invention addresses this need and other shortcomings in the
prior art.
BRIEF SUMMARY
[0004] In one aspect, a method and system for receiving and
distributing annotations of a digital work includes identifying a
digital work and receiving an annotation of the digital work. The
annotation may be stored in a database in association with the
digital work. A user desiring to access the annotation submits an
authorization credential that, if valid, enables the user to
receive the annotation of the digital work. The annotation may be
presented to the user in context with regard to the digital
work.
[0005] In some embodiments, a digital work may be annotated with
textual or graphical annotations. Examples of graphical annotations
include handwritten text and pictures, as well as typed text, clips
from other works, images, etc. Annotations may also include, for
example, highlighting of text in a digital work. If desired, an
annotation may be associated with particular content in a digital
work.
[0006] An annotation delivered to a user may be viewable concurrent
with a display of the digital work with which the annotation is
associated. In some embodiments, annotations may be normally hidden
and become viewable when a user positions a cursor or pointer near
particular content in the digital work to which the annotations
pertain. Indicators may be displayed with the digital work to
identify content in the digital work for which annotations are
available. If the digital work is an audio or audiovisual work,
indicators identifying annotations may be displayed with a playback
control provided for playback of the digital work. In yet other
embodiments, the availability of annotations for a digital work may
be identified by indicators in a listing of contents for the
digital work.
[0007] In another aspect, a user may obtain an authorization
credential for an annotation in exchange for compensation. The user
may then submit the authorization credential to obtain the desired
annotation. In some circumstances, the authorization credential may
represent compensation from the user. Where monetary compensation
is received for an annotation, some or all of the compensation may
be distributed to the author of the annotation. An indication of
satisfaction from the user to whom the annotation is provided may
be required before the compensation is distributed to the author. A
user may submit an authorization credential that is specific to an
annotation and have it considered as a request for the particular
annotation.
[0008] When multiple annotations are associated with particular
content in a digital work, a user desiring annotations may be
provided with a list that presents the multiple annotations in an
order determined by reference to a criterion. In some embodiments,
the criterion may be a ranking of the annotations assigned by
others who have previously viewed the annotations. In other
embodiments, the criterion may be a price assigned to each of the
annotations. In yet other embodiments, the criterion may be a date
of receipt of each of the annotations.
[0009] In another aspect, users that purchase a digital work may
automatically be given an authorization credential that enables
them to receive annotations of the digital work. Such annotations,
when combined with the digital work to which they pertain, may be
configured to become accessible to the user upon accessing the
digital work.
[0010] In another aspect, a user may be given an authorization
credential in exchange for performance of a specified action. For
example, an authorization credential may be given to a user as a
reward for electronically previewing a digital work or contributing
an annotation of a digital work.
[0011] Embodiments of the invention may also enable multiple
parties to be authorized distributors of credentials for access to
annotations. Members of a family, a group of students in a class,
or participants in a book club, for example, may annotate a digital
work and share their annotations with the others in their family or
group by distributing appropriate authorization credentials among
the family or group.
[0012] Computer systems may be configured to provide features and
aspects of the present invention. For example, a server system may
be configured to interact with a client system to receive and
provide annotations of a digital work. The server system may
comprise, for example, an interface for communicating with one or
more client systems, a memory, and a processor for executing
program instructions stored in the memory. The server system may
receive from a client system an annotation of the digital work. If
desired, the annotation may be associated with particular content
in the digital work. The server system may store the annotation in
the memory and upon receipt of a valid authorization credential
from a client system, the server system may provide the annotation
to the client system, possibly with an indication of the particular
content in the digital work to which the annotation pertains.

DETAILED DESCRIPTION
[0023] FIG. 1 provides an exemplary overview of one computing
environment in which embodiments of the invention may be
implemented. The depicted environment includes a server system 10
and one or more client systems 12, 14 communicatively connected by
a network 16. The client system 12 is shown associated with a user
18, and the client system 14 is shown associated with a user
20.
[0024] Also depicted in FIG. 1 are client systems 28, 30
communicatively connected to the server system 10 via the network
16. The client system 28 is shown associated with an author 32, and
the client system 30 is shown associated with an author 34.
[0025] The terms "user", "author" and "source" are generally used
herein. A "user" typically refers to a person, entity or device
that seeks to receive an annotation previously stored in
association with a digital work. An "author" typically refers to a
person, entity or device that prepares an annotation for storage
and distribution to users. A "source" typically refers to a person,
entity, or device that originates a digital work that may be
annotated by an "author". As should be readily appreciated, a
person, entity or device can be a source, an author and/or a user,
depending on the distribution of a digital work and whether an
annotation is being prepared or requested. Accordingly, at
different times, the users 18, 20 can be "authors" and the authors
32, 34 can be "users", and any of them (or some other third party)
may be the source of a digital work.
[0026] As will be described with regard to the particular
embodiments shown herein, the server system 10 is configured to
exchange data and information, including digital works and
annotations thereof, with the users 18, 20 who are operating the
client systems 12, 14 and the authors 32, 34 who are operating the
client systems 28, 30. In some circumstances, the server system 10
may be associated with a merchant, such as an online retailer
authorized to provide a marketplace for selling and distributing
digital works to consumers. Digital works, in the context of this
description, may include any type of content that can be stored and
distributed in digital form. By way of illustration, without
limitation, digital works can include all forms of textual
information such as books, magazines, newspapers, newsletters,
manuals, guides, references, photographs, articles, reports,
documents, etc., and all forms of audio and audiovisual works such
as music, multimedia presentations, audio books, movies, etc.
[0027] Digital works may be stored as media files in a digital
works database 22 that resides in or is otherwise communicatively
connected to the server system 10. An annotations database 24 and a
transaction information database 26 are also shown in FIG. 1
residing in or otherwise communicatively connected to the server
system 10 and will be described in greater detail below. The server
system 10, separately or together with the databases 22, 24, 26,
may provide an online marketplace 36 that can receive and
distribute annotations as well as the digital works to which the
annotations pertain.
[0028] The network 16 shown in FIG. 1 may be a local area network
(LAN) or a larger network, such as a wide area network (WAN),
collection of networks, or the Internet. Protocols for network
communication, such as TCP/IP, are well known to those skilled in
the art of computer networks. An author, such as author 32, may
operate a client system, such as client system 28, to request a
digital work from the server system 10 via the network 16. The
author 32 may also communicate annotations of a digital work to the
server system 10 for storage in the annotations database 24 and
distribution to others, such as the user 20. The user 20 may
operate the client system 14 to request digital works and/or
annotations thereof from the server system 10. As will be
appreciated by those skilled in the art and others, FIG. 1 provides
a simplified example of one suitable computing environment for
implementing embodiments of the present invention, and the
invention is not limited thereto.
[0029] When software formed in accordance with the invention is
implemented in one or more computer systems, for example, of the
type illustrated in FIG. 1, the computer systems provide a way for
authors and users to access digital works, provide annotations
thereto, and receive annotations of digital works. Providing a
mechanism for annotation of a digital work and providing a
mechanism for distribution of the annotation makes the underlying
digital work more useful and valuable by providing improved or
clarifying material in the digital work, updating material,
correcting material, adding academic interest or "color" to the
material, providing editorial comments to the material, etc.
Embodiments of the invention may be implemented such that authors
of annotations may receive some or all of compensation paid by
other users to access the annotations.
[0030] FIG. 2 depicts an exemplary computer architecture for a
server system, such as the server system 10, that may be used to
implement embodiments of the invention discussed herein. Of course,
persons skilled in computers will appreciate that other server
systems suitable for use may include more or fewer components than
those shown in FIG. 2.
[0031] The server system 10 shown in FIG. 2 is connected to the
network 16 (FIG. 1) using a network interface 60. The network
interface 60 includes hardware and software that allows the server
system 10 to communicate with other computing devices connected to
the network 16 by use of one or more suitable communication
protocols, such as TCP/IP.
[0032] The server system 10 shown in FIG. 2 further includes a
processor 50, a memory 52, a video display adapter 54, a disk drive
56, and an input/output interface 58, all of which are
communicatively connected together and to the network interface 60
by a communication bus 62. The memory 52 generally comprises RAM,
ROM, and/or other volatile or permanent memory. The memory 52 is
shown storing an operating system 64 for controlling the operation
of the server system 10. A binary input/output system (BIOS) 66 for
controlling the low-level operation of the server system 10 is also
stored in the memory 52.
[0033] The memory 52 additionally stores program code and data for
providing network services that allow client systems to exchange
information and data files with the server system 10. Accordingly,
the memory 52 may store a Web server application 68, which may be
provided by any one of a number of commercially available software
packages. The Web server application 68 comprises computer
executable instructions, that, when executed by the processor 50,
generate or otherwise obtain configurable markup documents such as
the sample Web pages shown in FIGS. 5-9, for display on client
systems. The Web server application 68 communicates with a database
manager application 70 and a transaction manager application 72
that facilitate additional functions of the server system 10
described below.
[0034] The video display adapter 54 provides display signals to a
local display (not shown in FIG. 2) permitting an operator of the
server system 10 to monitor and configure the operation of the
server system. The input/output interface 58 likewise communicates
with external devices not shown in FIG. 2, such as a mouse,
keyboard, scanner, or other input and output devices that can be
operated by an operator of the server system 10.
[0035] Further included in the server system 10 is a mass storage
74 comprising facilities such as one or more CD-RW/DVD-RW drives,
hard disk drives, tape drives, etc., or combinations thereof, that
are utilized to store digital content and information, such as
annotations. In the embodiment shown in FIGS. 1 and 2, the mass
storage 74 contains the digital works database 22, annotations
database 24, and transaction information database 26.
[0036] Turning back to FIG. 1, the client systems 12, 14 and 28, 30
may take the form of any one of a number of different computer
products and may include aspects of the computer architecture
illustrated in FIG. 2, where appropriate. For example, the client
systems 12, 14 and 28, 30 can include a network interface that
enables communication with other computing devices such as the
server system 10 via the network 16. Wired or wireless network
connections may be used with any suitable communication protocol,
such as TCP/IP. In general, the client systems 12, 14 and 28, 30
typically include a processor, a display, and a memory that stores
program code and data for operating the client systems. The memory
of the client systems 12, 14 and 28, 30 may also store an
application for browsing Web pages, such as the Web pages shown in
FIGS. 5-9.
[0037] The above-described computer systems may store software
instructions that, when executed, implement aspects and features of
the present invention. For example, such software can be stored on
a computer-accessible medium (e.g., magnetic or optical disk or
other device), or downloaded from a remote source, for loading into
memory 52 to be executed by the processor 50. For illustrative
purposes, described herein are embodiments of the invention that
allow authors and users to access digital works, to receive
annotations of those digital works from authors and to provide
annotations of digital works to users, typically in exchange for
some form of compensation or completed action by the user. Although
the illustrative examples described herein depict a Web-based
implementation, those of ordinary skill in the art will appreciate
that other embodiments of the invention may use other
implementations for communication and display of information to
authors and users.
[0038] FIG. 3 is flow diagram of one exemplary method 80 for
receiving and providing an annotation of a digital work. In this
particular embodiment, the method 80 begins at optional block 81 in
which a digital work is obtained from a source, including but not
limited to a publisher, a writer, or other originator of the work.
At block 82, the digital work is provided in a manner that the
digital work is accessible to others. As noted earlier, the server
system 10 may include a digital works database 22 with media files
containing all forms of digital content, such as books,
photographs, manuals, music, movies, etc. A directory of digital
works in the digital works database 22 may be provided to the
client systems 12, 14 and 28, 30 by the database manager 70 of the
server system 10. Files containing the digital works may be
requested, displayed, played back, or otherwise consumed by the
client systems 12, 14 and 28, 30. Delivery of digital works to the
client systems 12, 14 and 28, 30 may be accomplished in a variety
of ways including, but not limited to, downloading the digital
files, streaming the digital files from the server system 10, or
providing access to the digital works at a computer-accessible
source (e.g., by providing a URL to the digital work).
[0039] U.S. patent application Ser. No. 10/669,088, filed Sep. 23,
2003, which is commonly owned by the assignee of the present
invention and incorporated by reference herein, discloses
embodiments of systems that may be used in connection with
embodiments of the present invention. Such systems may include one
or more databases that include digital works in multiple
representations. One representation of a digital work may include
images of pages of content, while another representation of the
digital work may include text searchable forms of the content. The
content in the page images correlates with the text searchable form
of the content. The page images may be stored in a page image
database, while the searchable text may be stored in a text
searchable database. Images of pages of content may be acquired
using methods known in the art, such as scanning printed pages,
converting electronic text to document images, retrieving page
images from memory, receiving page images from others, etc.
[0040] For each image of a page of content, a recognition routine,
such as an optical character recognition (OCR), may be performed on
the page image to identify the text, position, and size of each
word on the page and provide a text searchable representation of
the page. A "word," in this context, may encompass any grouping of
one or more characters, numbers, or symbols. Moreover, a word may
stand alone or be associated with a non-text object, such as a
picture or graphic. OCR routines are well known in the art of
electronic document processing and do not require further
discussion herein. The resulting text, position, and size
information obtained from processing text on page images is may be
stored in the text searchable database.
[0041] The text searchable database may be organized as desired,
which may include using data structures optimized for full text
searching. In one suitable embodiment, each word in the text
searchable database has associated therewith content identification
numbers for digital works (e.g., SKU numbers) and page numbers
corresponding to the digital work and the images in the page image
database where the particular word is found. Furthermore, the text
searchable database typically includes information that identifies
the position and size of the text (and possibly non-text objects
associated with the text) as found on each respective page image.
In one implementation, the position and size information is
recorded as "quads," which include four numbers representing the X
and Y position and the width and height of the text as it appears
on a particular page image. All of this information may be encoded
in the text searchable database to reduce the storage space
required.
[0042] As will be described in more detail below, in some
embodiments an annotation may be received in regard to particular
content of a digital work. A text searchable database as discussed
above can be used to enable an author of an annotation (or other
person, entity or device) to indicate particular content in a
digital work and associate an annotation with the particular
content. As noted, the text searchable database may be constructed
to include information that helps identify the image(s) in the page
image database corresponding to the particular content. Thus, when
an author of an annotation indicates particular content in a
digital work by selecting text in the text searchable database, the
selected text not only identifies the particular content that the
author is annotating, but also identifies the corresponding page
image(s) in the page image database where the particular content is
represented. Word position and size information as discussed above
may be helpful in this regard in that it correlates text in the
text searchable database with the location of text as represented
in a corresponding page image.
[0043] Supposing, for example, the author 34 (FIG. 1) desires to
submit a comment on a digital work, provide updated or supplemental
material, or otherwise annotate a digital work, the author 34
enters the annotations into the client system 30. The author 34 may
enter the annotations into the client system 30 in a wide variety
of formats depending on the software and hardware provided at the
client system. In one format, for example, the author 34 may
operate a keyboard to enter text annotations into the client system
30. In another format, the author 34 may enter graphical
annotations, such as handwritten notes or drawings. The graphical
annotations may appear in context with regard to the digital work
being annotated, for example, in the margins, adjacent to, or
superposed over or near particular content in a display of the
digital work. Handwritten annotations may be particularly suited
where the client system 30 is a tablet PC or PDA with a sensitive
screen that readily accepts handwritten input. In another format,
the author 34 may annotate the digital work by providing an image
file containing an image pertaining to the digital work. When the
server system 10 receives an annotation of a digital work from an
author, such as author 34, the author may indicate one or more
particular locations or content in the digital work to which the
annotation pertains. In some implementations, the author 34 may be
required to sign in or otherwise submit an identification before
the author is allowed to submit annotations to the server system
10.
[0044] As indicated at block 84 in FIG. 3, the server system 10 may
receive annotations of a digital work from an author. In a
circumstance where author 34 is providing annotations to the client
system 30, the client system 30 communicates the annotations to the
server system 10 via the network 16. Annotations received by the
server system 10 may be stored in the annotations database 24, in
association with the digital work, as indicated at block 86.
Storing an annotation in association with a digital work may be
accomplished in any suitable manner, including simply storing the
annotation in the annotations database 24 with an indication of the
digital work to which the annotation pertains, and if apt, the
particular content within the work to which the annotation
pertains. Typically, the operator of the server system 10 has
previously secured an agreement with the author concerning any
copyright or other proprietary interest the author may claim in
annotations submitted to the server system 10.
[0045] Embodiments of the present invention have a wide
applicability of which the following examples are only a small
part. The following examples give selected contexts for
appreciating several advantages of the invention. An annotation,
for example, may be a critique or alternatively a summary of the
digital work. An annotation may be a separate essay on the same
topic presented in the digital work. Annotations may be words,
graphs, formulae, files, images, enhancements, etc., provided by
the user. For example, a user may wish to annotate a travel book by
providing recent images of locations described in the travel book.
For digital works that are audio, such as music files, authors can
annotate the music files with additional content commenting on the
songs, providing background information on the singer or the
recording process, alternative lyrics, technical information as to
the composition, related musical compositions, etc. In a
circumstance where the digital work is a cookbook, for example,
authors may submit alternative ingredients that enhance a recipe,
ingredients that make a spicier dish, ingredient substitutions
considered to be lower in fat or carbohydrates, etc. In another
circumstance, a student or teacher as an author may provide a
markup of an academic textbook. As can be appreciated from the
foregoing, there is virtually no limitation to the type, form and
content of annotations that can be added to a digital work. By way
of illustration, an annotation can also be in the form of a link or
address to another page, file, or document available to the server
system or the client system(s).
[0046] A user, such as the user 18 shown in FIG. 1, obtaining a
digital work from the server system 10 may be notified by the
server system 10 that annotations to the digital work are
available. If desired, the server system 10 may present one or more
summaries of the annotations or portions of the annotations to the
user 18 for a preview.
[0047] As indicated at block 88 in FIG. 3, the server system 10 may
receive a user request for an annotation of a digital work. This
request typically identifies the digital work and possibly the
particular annotation desired. Depending on implementation,
distribution of annotations of digital works may be limited to
users having an appropriate authorization credential that, when
presented to the server system 10 and validated, enables the user
to receive the requested annotation. Additional discussion of
authorization credentials is provided below. As indicated at
decision block 90, the method 80 determines whether the user has
presented an authorization credential. If not, the method 80
terminates at block 92 by denying the user access to the requested
annotation. If an authorization credential has been presented, the
method 80 determines at decision block 94 whether the authorization
credential is valid. If the authorization credential is not valid,
the method 80 terminates at block 92 by denying the user access to
the annotation. Otherwise, the annotation of the digital work is
provided to the user at block 96. Delivery of an annotation to the
user may be accomplished by downloading the annotation, streaming
the annotation from the server system 10, or providing access to
the annotation at a network source (e.g., by providing a URL to the
annotation), possibly together with and perceptibly associated with
some or all of the digital work to which the annotation
pertains.
[0048] Authorization credentials presented by users may take any
form appropriate for processing in the server system 10. For
example, an authorization credential may be a token comprised of
symbols or an alphanumeric code that is recognized in the server
system 10. Users may obtain authorization credentials for accessing
annotations in various ways. For example, a user purchasing a
digital work may automatically receive an authorization credential
to receive present and/or future annotations of the digital work
without charge. Alternatively, a user may provide some form of
compensation to the server system 10, such as a monetary payment or
other item or representation of value. A user may also receive an
authorization credential as an incentive for performing an action
specified by the server system 10. For example, a user may receive
an authorization credential for electronically previewing a digital
work or purchasing one or more related digital works or
annotations. Users may also receive authorization credentials for
performing actions such as filling out surveys, participating in
games, or providing annotations to digital works. In some
circumstances, free access to annotations may be provided by simply
giving the user an authorized credential when the user requests
access to the annotation.
[0049] The server system 10 is configured to receive an
authorization credential from a user requesting an annotation and
determine whether the credential is valid, thus enabling the user
to access the annotation. A user's authorization credential can be
determined valid in any suitable manner, including comparing a
user-submitted credential to a list of known credentials that have
been authorized and distributed to users. Use of a credential may
cause the credential to be removed from the list in this example,
in cases where the credential is intended for a single use.
Validation of an authorization credential may be separately
communicated to the user or simply followed by delivery of the
requested annotation to the user.
[0050] In other embodiments, an authorization credential may be
generated and distributed for use with a specific annotation or
group of annotations and as such, may be used only to authorize
access to the specific annotation or group of annotations.
Moreover, depending on the format of the authorization credential,
the authorization credential may itself identify the annotation to
which it pertains. In that case (where the authorization credential
identifies the annotation), embodiments of the invention may be
configured to receive the authorization credential and
automatically consider it as a request for the annotation. A user
may thus request an annotation and present the authorization
credential in a single step.
[0051] Authorization credentials can be advantageously used to
create a market for distribution of annotations to others. For
example, where a user intends to submit monetary compensation for
annotations, the user may be given a price list for annotations to
a digital work. The user can then select which annotations the user
desires to receive and pay for the annotations. In other
embodiments, a subscription model may be used where the user pays a
monthly or annual fee to have access to certain groups or all
available annotations. Commercially-available payment processing
systems may be used by an online marketplace 36 (FIG. 1) to receive
a payment from the user for annotations.
[0052] Another aspect of creating a market for annotations of
digital works is to provide incentive for users to submit
annotations. FIG. 4 illustrates a flow diagram of a method 100 in
which monetary compensation is paid for an annotation and some or
all of such compensation is distributed to the author of the
annotation. At block 102, the server system 10 receives a payment
from a user for an annotation, records the transaction in the
transaction information database 26, and provides the user an
authorization credential to access the annotation. Compensation
received from the user may be paid directly to the author of the
annotation, or, as illustrated at block 104 in FIG. 4, some or all
of the payment may be stored in a separate account by the
transaction information database 26 for distribution to the author.
Distribution of compensation to the author may be conditioned on
the user's satisfaction with the annotation. At block 106, feedback
regarding the annotation is received from the user. If, at decision
block 108, the user's feedback indicates that the annotation was
satisfactory, some or all of the payment stored at block 104 is
distributed to the author of the annotation. If the annotation was
not satisfactory to the user, the server system 10 may process a
refund of the payment to the user, as indicated at block 110.
[0053] It should be noted that "authors" and "users" can be, and
typically are, distinct from the persons, entities, or devices that
are the creators, originators, producers, publishers, distributors,
or other "sources" of digital works to be annotated. To further
illustrate distinctions between "authors", "users", and "sources",
consider a person A who writes a book that publisher P publishes in
hardbound, paperback, audio (e.g., "books on tape"), and/or digital
forms (e.g., electronic books that can be viewed using a suitable
device incorporating a visual display), these forms of the book
being distributed to the public, for example, through retail
outlets such as book stores, book clubs, and online marketplaces
accessible via computer networks. As to the last, publisher P may
authorize the limited reproduction of all or selected portions of
the book by such online marketplaces for promotional purposes.
[0054] Now consider a person B who wishes to write a review of the
book, as for a newspaper, magazine, online journal, or even for one
of the online marketplaces that offers the book for sale. In
accordance with suitable embodiments of the invention, person B's
review can be (or can become) an annotation to A's book, given
proper authorization(s) by A, P, and/or B for this to occur, and
can be bought, sold, traded, rented, etc., at the same online
marketplace as A's book and/or at other online marketplaces or
retail establishments. B's review need not be limited to a
conventional self-contained review essay that is written to be read
separately from A's book. Instead (or additionally), in accordance
with embodiments of the invention, B may write some or all of the
book review as a set of annotations that pertain to, and are fully
understandable when read in context with, specific sections or
passages of the book.
[0055] For example, B's review may focus on textual passages or
pictures or diagrams in A's book that, to B's sensibilities, seem
particularly noteworthy, and link or associate these with
corresponding portions of the review. In other words, B annotates
the passages or images, and the annotations, taken together, make
up some or all of B's book review.
[0056] With A's original work and B's review now available, it
becomes possible for another person C to annotate both A's book and
B's review thereof, as digital works. A and/or B may, if they
choose, respond to C's comments and to one another, with all these
comments and responses being added as yet further annotations to
A's book, suitably limited to or associated with pertinent passages
and/or prior annotations, as appropriate, that are read in context
with the pertinent sections or passages of the book.
[0057] The entire set of annotations or subsets thereof (e.g., only
C's annotations, or only A's responses, or only annotations made at
the behest of publisher P) can be made available with appropriate
authorizations from A, B, C, and P, as may be necessary (or, in
some instances, under the doctrine of fair use or other legal
rubric without prior authorization) for purchase, rental, exchange,
or other use by a consumer D. Thus, A and P may be considered
"sources" in this example; B, C and A (in the role of responding to
B's and C's annotations) may be considered "authors"; and D may be
considered a "user". Further, a particular online marketplace M (or
other forum in which annotations and annotated digital works
according to the invention are made available to "users") may be
considered none of these, although it will be appreciated that in
some situations where publisher P owns marketplace M or vice versa,
or where A self-publishes a book through M without the assistance
of a conventional publisher P, M may be viewed as a "source".
[0058] As will be described below in reference to FIGS. 5-9,
annotations of a digital work may be viewable concurrent with or
separate from a display of the digital work. Annotations may be
received in graphical form, including handwriting. Annotations may
also include highlighting of text in the digital work. In some
circumstances where annotations are associated with particular
content in the digital work, the annotations may be presented in a
manner such that the annotations are normally hidden and become
viewable only when a user positions a cursor or pointer near the
particular content in the digital work. Techniques for recognizing
the position of a cursor or pointer within a digital work displayed
on a screen are known in the art.
[0059] Furthermore, indicators may be included in the digital work
to identify particular content having annotations. In a textual
digital work for example, the indicators may appear as footnotes,
graphical icons, symbols, characters, or other indicia that are
located with the text. Where the digital work is an audio work or
an audiovisual work, an annotation associated with particular
content in the digital work may be identified by an indicator in a
playback control provided for playback of the digital work. In yet
another alternative, a digital work having annotations pertaining
to particular content in the digital work may provide a listing of
contents for the digital work with indicators in the listing of
contents identifying the location of the annotations.
[0060] Turning now to the example given in FIG. 5, a browser
program 120 may be used to depict a Web page to a user. In the
embodiment shown in FIG. 5, the Web page includes a display of a
digital work 122, here comprising a manual for a cordless
telephone. The digital work 122 shown provides instructions for
installation of a new battery back in a telephone handset. The
digital work, in this example, is textual in form.
[0061] Displayed with the digital work 122 are indicators 124, 126
indicating the presence of annotations to the digital work. The
indicators 124, 126 may be graphical icons, characters, or symbols
that are simply displayed with the digital work. Alternatively, the
indicators 124, 126 may provide active links that initiate the
display of corresponding annotations when a user activates (e.g.,
checks or clicks on or hovers over) the indicators 124, 126.
[0062] The Web page illustrated in FIG. 5 further includes a
section 128 for displaying annotations of the digital work 122. In
some embodiments, the annotations 128 may be displayed in a frame
that is separate from a frame in which the digital work 122 is
displayed. Activating the indicators 124 and 126 in the display of
the digital work may cause the annotations section 128 to appear.
The particular annotation associated with the indicator 124, 126
that the user has activated may appear highlighted, if desired.
Annotations may also be associated with the indicators 124, 126 by
use of a suitable numbering system where numbers in the indicators
124, 126 correspond to numbers (not shown) associated with each of
the annotations.
[0063] FIG. 6 is a pictorial diagram of a Web browser 130 providing
another exemplary Web page formed in accordance with an embodiment
of the present invention. In this embodiment, textual annotations
138 are presented, but in a separate window that may appear
superposed on the display of the digital work 132. This embodiment
is particularly suited to environments where the user may activate
indicators 134 and 136 to cause the annotations window 138 to
appear. Typically, the annotations window 138 provides a way for
the user to close the window so the user may continue to read the
text of the digital work 132, if any, hidden behind the annotations
window 138. Standard windowing technology may also be used to
permit the user to resize or move the annotations window 138 within
the display of the Web browser 130.
[0064] In yet another embodiment of the invention, a Web browser
140 as shown in FIG. 7 may provide a Web page display of a digital
work 142 in which annotations 144 and 146 are presented in a
graphical, handwritten format. The handwritten annotations 144 and
146 may be displayed just as they are received from the author of
the annotations. Of course, such annotations can include graphical
drawings as well as handwriting. An annotation may also be provided
in the form of a color or bold highlight 148 that is displayed with
the text of the digital work 142. As shown in FIG. 7, the
annotations 144, 146, 148 may be configured to appear to a user
superposed on an image of the digital work.
[0065] Digital works and/or annotations may also be received from
authors and presented to users in an audio or audiovisual form, as
illustrated in FIG. 8. FIG. 8 depicts a Web browser 150 with a Web
page that includes a playback control 152. The playback control 152
provides a graphical depiction of an audio or audiovisual file and
typically represents the duration of the audio or audiovisual file.
Additional playback controls 153 may be provided to control the
playback of the file. Where the digital work is an audiovisual
work, the visual portion of the digital work may be displayed in a
section 154 of the Web page.
[0066] Annotations to the audio or audiovisual work may be
indicated by indicators 156 and 158, for example, associated with
the playback control 152. In the embodiment shown in FIG. 8, the
annotations 156 and 158 are associated with particular content in
the digital work. For instance, where the digital work is an audio
recording of the installation manual shown in FIGS. 5-7, the
annotations may be associated with particular steps in the
installation as they occur in the audio recording. Activating the
indicator 156, for example, may cause a window 159 to appear with a
textual annotation associated with the particular installation step
being described in the audio playback.
[0067] Alternatively, a digital work may be presented in textual
form with annotations in an audio or audiovisual format. Activating
an indicator in the display of the digital work may cause a
playback control 152 and controls 153 to appear for operating the
playback of the annotation to the digital work. If the annotation
of a digital work is an image, activating the annotation indicator
in the digital work may cause a window, such as window 154, to
appear with the image annotation. As should be appreciated from the
foregoing, the presentation and format of annotations of digital
works is not limited.
[0068] FIG. 9 illustrates yet another embodiment of the present
invention in which multiple annotations for the same content in a
digital work are presented to the user in a form of a list. The Web
browser 160 in FIG. 9 is shown displaying a Web page with a digital
work 162 in textual form. Indicators 164 and 166 in the digital
work 162 indicate the presence of one or more annotations. Should a
user activate the indicator 164, for example, an annotations window
168 may appear providing a list of annotations to the user. The
annotations in the list may be presented to the user in an order
determined by reference to a criterion. For example, one criterion
may be a ranking of the annotations assigned by others who
previously have viewed and "voted" on the quality of the
annotations. Those annotations having a higher ranking may be
presented first. In circumstances where annotations are provided to
users in exchange for monetary compensation, the users are more
likely to select those annotations previously deemed to be of
higher quality.
[0069] Another criterion for ordering a list of annotations is the
price assigned to each of the annotations. A user may choose to
have the lowest priced annotations or the highest priced
annotations listed first. Yet another criterion for determining the
order of annotations is the date of receipt of each of the
annotations. For example, annotations that are more recent may be
presented above annotations that are older. Other suitable criteria
can be readily recognized by persons having ordinary skill in the
art.
[0070] In some circumstances, user receipt of annotations may be
conditioned on prior purchase of the digital work to which the
annotations pertain. Conditioning the receipt of annotations on the
purchase of the underlying digital work provides incentive to users
to purchase the work. Moreover, authors of underlying digital works
are more likely to grant permission to users to add annotations to
the digital work, where such permissions are necessary. A user's
purchase of the underlying digital work may be recorded by the
transaction manager 72 in the transaction information database 26
and later referenced when the user requests the annotations to the
digital work.
[0071] Also as noted earlier, authors submitting annotations may
indicate particular content in the digital work to which the
annotations pertain. Where the digital work is, for example, a
book, annotations may pertain to the whole work or particular
portions of the work, for example, a chapter, certain pages, or
certain text on a page.
[0072] Further embodiments of the invention may allow users to
receive authorization credentials to access annotations from one or
more authorized distributors of credentials. For example, an entity
providing only annotations to digital works may have a relationship
with an online retailer that permits the online retailer to give
authorization credentials to purchasers of digital works, which
authorization credentials are valid for use in accessing
annotations of the purchased works from the entity. In another
circumstance, the author of an annotation may become an authorized
distributor and distribute authorization credentials to others,
allowing them to access the particular author's annotations.
Distribution of access credentials in this manner may be
advantageous where an author wishes to provide access to his or her
annotations to selected family, friends, etc. For example, a group
of students in a class or book club may each annotate a digital
work and share their annotations with the others in their group by
appropriate distribution of authorization credentials among the
group. In yet another environment, a publisher may be an authorized
distributor that distributes valid credentials for accessing
annotations to works published by the publisher.
[0073] In still further embodiments of the invention, a
computer-implemented method may be provided which includes
obtaining a first representation of a digital work, the first
representation comprising one or more images. A second
representation of the digital work is obtained, the second
representation comprising content of the digital work in a form
that allows particular content of the digital work to be indicated.
The particular content is correlatable with one or more locations
in the one or more images at which the content is represented. The
method further includes receiving an annotation of the digital work
in regard to indicated particular content of the digital work, and
providing to a user the annotation in context with regard to the
digital work. In regard to the latter, one or more images of the
digital work may be provided to the user such that the annotation
is perceptibly associated by the user with the particular content
in the digital work. For example, the annotation may be configured
to appear to the user superposed on one or more of the images of
the digital work. Alternatively, the annotation may be configured
to appear adjacent to one or more of the images of the digital
work. The one or more images may further include an indication of
the particular content to which the annotation pertains. The
indication of particular content to which the annotation pertains
is typically received from the author of the annotation, though it
may be received from others.
[0074] As previously noted, the annotation may be received from an
author that is different than the source of the digital work.
Likewise, the user to whom the annotation is provided may be
different than the source of the digital work. It should be
recognized that an annotation of a digital work may be further
subject to annotation by another author.
[0075] In some embodiments, the annotation may be provided to the
user via an online marketplace. If desired, the annotation may be
provided to the user together with the digital work via the online
marketplace.
[0076] While several exemplary embodiments of the invention have
been illustrated and described above, it will be appreciated that
various changes can be made therein without departing from the
spirit and scope of the invention. The scope of the invention,
therefore, should be determined from the following claims and
equivalents thereto.
