In some implementations, a device displays a user interface that provides supplemental information in connection with a digital work. For example, the supplemental information may include a listing of objects identified in the digital work. Further, a visual representation may be displayed with each listed object. The visual representation for each listed object may provide a representation of at least one location of at least one occurrence of the object in the digital work. The objects may be displayed according to a supplemental information view, a page view, a chapter view, a book view, a series view, a library view, or the like. Additionally, one or more object buttons may be displayed concurrently with the listing of objects. The object buttons may correspond to the types of objects displayed, and may be selected to limit the displayed objects to a particular type.

Providing supplemental information for a digital work in a user interface

Troubleshooting, training, and other services that can be provided remotely to a user of an application, Web page, or similar component can take advantage of a lightweight approach to monitoring, viewing, and/or control. A page being viewed by a user can have client executable code contained therein, wherein actions of the user with respect to the page can generate events that can be sent to a remote queue, service, server, etc. A local copy of the page can be created that can be viewed and/or operated by a person providing the service to the user. A listener component can be configured to retrieve events from the queue, etc., and send those events to the local device such that the local copy can be updated, causing the local copy to accurately reflect what the user is seeing and doing with respect to the page.

Lightweight browser monitoring and viewing

In some implementations, a first user associated with a first user account may send a request to exchange digital libraries with a second user associated with a second user account. Upon acceptance, the second user receives first library information associated with the first user account that identifies content items that may be accessed by the second user due to the exchange. Similarly, the first user receives second library information associated with the second user account that identifies second content items that may be accessed by the first user. In other examples, a user may access the digital library of a selected person or entity, such as a historical figure, celebrity, author, friend, or organization. Additionally, in some cases, a user may view content of a content item that a selected person is currently reading, and which may include annotations made to the content item by the selected person.

Sharing digital libraries

In some implementations, a device displays supplemental information in connection with a digital work. The supplemental information may include a visual representation that represents one or more occurrences of an object in the digital work. The visual representation may include an area representative of an expanse of the digital work. At least one marking is located in the area in correlation to a location of an occurrence of the object in the digital work. In some examples, the visual representation may include a plurality of markings representing multiple occurrences of the object in the digital work, with a first or leftmost marking positioned in the area in proportion to a first occurrence of the object in the digital work. A second or rightmost marking may be positioned in the area in proportion to a final occurrence of the object in the digital work.

Visual representation of supplemental information for a digital work

In some implementations, text is extracted from a digital work and proper nouns are identified in the text to generate a list of names. The list of names may be sorted so that names containing more information are positioned toward the beginning of the list. The list may be traversed to cluster names and alternate names into name sets that correspond to particular entities in the digital work. Non-unique names that appear in more than one name set may be disambiguated based on proximity to unique names in the same name sets to determine which occurrences of the non-unique names belong with which name sets. Furthermore, a representative name may be selected from among multiple names in a name set for use in representing an entity or object corresponding to the name set. In some examples, the representative name may be selected based on a fullness of the name.

Identifying entities in a digital work

In some implementations, a service provider may enable location-based interaction of a user of a device with at least one of a digital work or another user. For instance, when the service provider determines that the device of the user is at a particular physical location, the service provider may send a communication to notify the user that one or more digital works are available to be accessed at the current physical location of the device. As one example, a digital work may have been virtually left at the location by another user, and the digital work may be available to be accessed by the user currently at the location. As another example, the user may be attending an event and the service provider may offer a digital work related to the event when the user is determined to be at the location of the event.

Location-based interaction with digital works

In some implementations, text is extracted from a digital work and a plurality of noun phrases are identified. The noun phrases are checked against a network accessible resource, such as an online encyclopedia, that includes a plurality of interlinked article entries. The noun phrases that have corresponding entries in the network accessible resource are included in a set of candidate topics. The candidate topics are ranked based, at least in part, on the links to and from each of the entries corresponding to the candidate topics. Candidate topics below a ranking threshold are removed from the set of candidate topics. Further, term frequency information for each candidate topic in relation to the digital work is compared against term frequency information for the candidate topic in a large corpus of textual works to remove candidate topics within a frequency difference threshold.

Identifying topics in a digital work

In some implementations, a digital work may include a plurality of objects that may be selected to view supplemental information. A supplemental information user interface may include a listing of objects from the digital work. For instance, the listing may include a selected object appearing at an identified location in the digital work. The user interface may further present a visual representation displayed with each object that provides an indication of at least one location of at least one occurrence of the corresponding object in the digital work. In some examples, a user may navigate between a supplemental information view user interface, a page view user interface, a chapter view user interface, a book view user interface, a series view user interface, and/or a library view user interface to view occurrences of a particular object in the digital work or other digital works.

Navigating supplemental information for a digital work

An electronic device may present an interface providing information related to one or more content items. For example, the interface may present representations related to a plurality of content items to indicate relative values among the content items of at least one metric. Additionally, each representation may further indicate at least one of a quality of the value of the metric or a different metric value. A user may navigate the interface to more specific or more general views for a particular metric, characteristic and/or category, and may use the interface to view more information about a selected content item. Alternatively, the representations may represent, or may be arranged according to, authors, publishers, genres, etc. In some examples, the representations may represent terms obtained from content items that satisfy one or more metrics, such as terms that occur in content items sold within a specified period of time.

Presenting information related to content items

In some implementations, a user of an electronic device may select a term of one or more words from the text of a displayed digital work. In response, a dictionary module may select a particular dictionary to access from among a plurality of dictionaries available on the electronic device. For example, based at least in part on metadata corresponding to the displayed digital work, the dictionary module may select a dictionary to access from a hierarchy of dictionaries. The dictionary module may present a definition obtained from the selected dictionary in a dictionary interface displayed over the presentation of the digital work. Further, the dictionary module may identify a location of at least one other occurrence of the selected term in the digital work or in a different digital work, and may display an excerpt of text including the at least one other occurrence of the selected term.

Dynamic dictionary based on context

In some implementations, a user may select a category, attribute or term related to content item. During presentation of the content item, an electronic device may visually distinguish (or, alternatively, hide) at least one portion of content associated with the selected category, attribute or term. In some examples, a user interface may be displayed to enable the user to select one or more categories, attributes, or terms related to the content item. The user interface may further enable the user to select a graphics scheme to be used for visually distinguishing at least one portion of content corresponding to the selection. Selection information identifying a portion of content to be visually distinguished or hidden may be sent to a content provider, such as for synchronization with other instances of the content item on other devices of a user, or for aggregation of the selection information by the content provider.
