In the present invention, digital content may collectively refer to a digitized document made by applying HTML and XML, which are standard languages of the Internet. In particular, digital content may refer to e-book based content.

The server system implements an e-book based service model that provides digital contents to user terminals, creates annotations requested by users on digital contents, and extracts and utilizes items with multiple annotations from digital contents. An annotation function can be provided. For example, the server system provides digital content to the user terminal in the form of an online service while maintaining a connection with the user terminal through a network such as internet communication or mobile communication, and provides an annotation function for the digital content. Can provide. The server system may provide an e-book service having the same function to various platforms such as an e-book dedicated terminal, a PC, a tablet, a portable terminal (smart phone, etc.). As another example, in the present invention, an e-book-only application including a viewer function for digital content and an annotation function for digital content for a local environment of a user terminal in relation to an e-book service (hereinafter, 'e-book) App "). The e-book app may basically provide a service environment for storing, managing, and consuming digital content in the local state of the user terminal. In addition, the e-book app may provide a service environment such as managing, consuming, and sharing with other users digital content stored on the server system through the interaction between the user terminal and the server system. In the present invention, the e-book app extracts items in which a plurality of annotations are made from digital content, and provides the number of annotations for each content or item based on the content, and enables users to intuitively recognize the items that the annotations have been made. UI (User Interface) environment can be provided.

The user terminal provides a viewer function, an annotation function, or the like for digital content, and may be implemented as an e-book dedicated terminal, a PC, a tablet, a portable terminal (smartphone, etc.), and / or a combination thereof. The user terminal may refer to all communication terminals capable of installing the e-book app and communicating with the server system.

The user terminal may include a touch sensitive display as an example of the display means. The point of contact between the touch-sensitive display and the user may correspond to one or more fingers or a stylus pen of the user. The touch-sensitive display may use LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or the like, but other display technologies may be used in other embodiments. The touch sensitive display can further include proximity sensor arrays or other elements for determining at least one contact point with the touch sensitive display.

The touch-sensitive display may display a UI screen such as a graphical user interface (GUI) including at least one window. The at least one window may be used to display digital content through the e-book viewer or display the content and number of annotations applied to the digital content. The GUI may recognize a user experience (UX) input according to a contact point of a user based on various types of input interfaces such as gestures and icons. In the GUI, different functions may be predefined and set for each gesture motion or icon. That is, the user terminal may recognize a touch input by the user through the GUI of the touch sensitive display, and execute the corresponding function in response to the recognized touch input.

In the present embodiment, a function of selecting some objects from the digital content displayed on the screen of the touch-sensitive display (hereinafter, referred to as an object selection function) and an annotation function of applying annotation to the selected object may be provided. . Regarding the object selection function, one or more fingers touching the touch-sensitive display can be held still for one second or longer, or in advance, such as <,>, {,}, (,), [,], ",", etc. It may be recognized when a defined predetermined gesture motion is input. The annotation function recognizes when a menu related to annotation is selected after a predetermined object is selected through the object selection function, or when the menu related to annotation is dragged and dropped onto an object to be selected by the user. Can be.

Hereinafter, a method of generating and managing annotations for a selected object in an e-book based digital content, and a method of extracting and utilizing items in which a plurality of annotations are created from digital content will be described. The UI screen of the touch-sensitive display may have a different configuration or function according to a service type of digital content, an operating system of the system, or a UI environment. The UI screen described below describes a general viewer screen such as a smart phone or a tablet as an example. However, this is not limited to the embodiments of the drawings and the detailed description. Modifications may be made.

1 is a flowchart illustrating an annotation management method for generating and managing annotations in digital content according to an embodiment of the present invention, and FIG. 2 is an exemplary diagram for describing a structure of generated annotation data. Hereinafter, a method and an embodiment of generating annotations for a predetermined object selected from digital content will be described with reference to FIGS. 1 and 2.

The digital content is displayed on the screen of the touch-sensitive display provided in the user terminal by the content display code of the e-book app (110). For example, the user terminal may directly execute the e-book app as a local-based program, or execute the e-book app as an online service through a connection with a server system. Accordingly, the e-book app may be stored in a memory of the user terminal and executed by a processor inside the user terminal or may be executed through a browser of the user terminal for using a viewer environment provided by the server system. The e-book app renders the digital content by the content display code, and at this time, the content layer in which the digital content is rendered may be output on the screen of the touch-sensitive display.

Thereafter, the object selected by the user may be recognized in the digital content displayed on the touch-sensitive display by the object recognition code of the e-book app (120). In the present invention, the object may mean not only texts based on at least one of words, sentences, and paragraphs, but also all objects included in digital content such as images, videos, and audio. When the object selection function is recognized through a user's touch input with respect to a predetermined object in the digital content displayed through the touch-sensitive display, the object corresponding to the position where the object selection function is recognized is displayed as a selection target according to the object selection function. Can be.

Subsequently, after generating the annotation data by applying the annotation requested by the user to the object selected through the object selection function by the annotation storing code of the e-book app, the generated annotation data is stored in association with the user (130). . In the present invention, the annotation function may collectively refer to all methods of expressing additional information by the user to the digital content. For example, if you apply various types of applications to the original content such as bookmarking, underlining, highlighting, adding notes, and discussing, all of the data may be annotation data.

For example, the annotation data generated for the object selected by the user includes an individual ID (Annotation_id) 201 of annotation data, content information (Annotation_content_info) 202 associated with the object, and the annotation data as shown in FIG. Identification information (Annotation_owner_info) 203 of the user who created the annotation, application information (Annotation_application_info) 204 of the annotation applied to the object, and data information (Annotation_info) 205 generated when generating an annotation on the object. It may be generated in a structure including at least one of. Here, the individual ID 201 of the annotation data is a unique value given at generation, and may be used to provide information about what content and where the individual annotation is connected to. In addition, the content information 202 may include an ID value Content_id of the corresponding digital content in which the object is selected and a location value Content_locator of the object in the digital content. For example, the position value of the object means position information stored when the digital content is rendered, and may be represented by the content rendering width and the content rendering height of the entire content during rendering. In addition, the identification information 203 of the user provides information on which user the individual annotation was generated, and may utilize a nickname, ID, and the like previously registered in the e-book app. In addition, the application information 204 may include a unique value (Annotation_application_id) previously assigned to each application such as a bookmark, an underline, a highlighting function, and a discussion function. In addition, the data information 205 is data information generated when an annotation is generated in an object. The data information 205 includes an annotation creation time (Annotation_date), type information (Annotation_object_type) for distinguishing an object type, and actual data corresponding to the object. Annotation_object_data). When an annotation generation date (Annotation_date) is utilized, duplicate annotations may be generated for the same object having the same content. The type information of the object can be divided into audio, video, image, text, etc., and the actual data of the object is low data in the form of <data value from 23345byte to 23450byte in content1.xml>. Link information on file may be provided. In the present invention, the duplicated information, for example, the number of annotation data generated for the same content may be searched based on the annotation data having the above-described structure.

3 is a flowchart illustrating a display method of expressing annotation data according to an embodiment of the present invention, and FIGS. 4 and 5 are exemplary views of a user interface screen displaying annotation data. Hereinafter, a method and an embodiment of expressing annotation data generated in digital content will be described with reference to FIGS. 3 to 5.

In order to express annotation data in the digital content, the annotation data may be expressed in the form of adding an additional layer in the form of an overlay to the rendered content (310). The e-book app may render annotation data by the annotation display code, and in this case, the annotation layer on which the annotation data is rendered may be overlaid on the content layer and displayed on the touch-sensitive display of the user terminal.

For example, as shown in FIG. 4, the annotation data for the content may be provided in the form of adding the annotation layer 420 in the form of an overlay on the content layer 410 on which the content is rendered. In this case, the annotation layer 420 may be rendered based on annotation data generated and stored through annotation storage code for a predetermined object of content. In rendering annotation data, for example, annotation data of <Annotation_id: 1, Content_id: wikipedia.org/ star, Annotation_owner: sunupnet, Annotation_application_id: basic_02, Annotation_info: Ddf # gweD> For example, an underline mark 521 is expressed on the annotation layer 520 at a position corresponding to the object, and <Annotation_id: 2, Content_id: wikipedia.org / star, Annotation_owner: sunupnet, Annotation_application_id: basic_12, Annotation_info: JFH3lk For annotation data of $%>, an important mark 522 is displayed on the annotation layer 520 at a position corresponding to the object. <Annotation_id: 3, Content_id: wikipedia.org/ star, Annotation_owner: sunupnet, Annotation_application_id: basic_05, Annotation_info: KLJE8 # CK> shows the box mark 523 on the annotation layer 520 at the position corresponding to the object. Can. On the other hand, when users share or share annotation data on a selected object with other users (eg, a user's friend, etc.) using the sharing setting function, the server system may use an external search engine or an application programming interface (API). It is possible to collect annotation data that is allowed to be disclosed between users through the user and transmit the annotation data to the corresponding user terminal.

Therefore, the user terminal and server system providing the annotation function according to the present invention can provide the annotation function for the digital content without modifying the existing form of the digital content, and the user can simply read the content. In addition, various annotation functions can be used to create annotations of the desired level for the content being read.

FIG. 6 is a flowchart illustrating a method of extracting items for which a plurality of annotations have been created according to an embodiment of the present invention, and FIG. 7 illustrates an annotation graph of extracted items according to an embodiment of the present invention. It is an example of the interface screen provided. Hereinafter, a method and an embodiment of extracting and providing an item in which a plurality of annotations are made from digital content will be described with reference to FIGS. 6 and 7.

In the present invention, duplicate information may be searched based on information on which content and content of an individual annotation are connected by an annotation count code of an e-book. To this end, the user terminal or server system may extract all annotation data created by users who have subscribed to the digital content and use it for information retrieval to extract items for which a plurality of annotations have been created from the digital content. For example, the number of annotation data generated from the same content may be counted based on the ID value Content_id of the digital content connected to the individual ID Annotation_id of the annotation data. As another example, the content of digital content is generated from the same item for each item (eg, paragraph, chapter, etc.) classified based on the location value (Content_locator) of the object linked to the individual ID (Annotation_id) of annotation data. The number of generated annotation data can be counted. As another example, the number of annotation data generated for the common object may be counted based on the actual data (Annotation_object_data) of the object connected to the individual ID (Annotation_id) of the annotation data.

For example, a procedure for checking duplicate annotations is shown in FIG. 6. First, a count of Annotation_id may be generated for each Content_id (610). To this end, while selecting Annotation_id for all annotation data in turn (611), after checking Content_id connected to Annotation_id, a count may be accumulated (+1) for each content ID temporarily assigned to each Content_id ( 612). The process of steps 611 and 612 is repeated until the last Annotation_id (613). In addition, a count for each Content_locator may be generated for the same Content_locator among the same Content_id (620). To this end, counting may be accumulated for the same Content_locator while selecting Content_locator for each Content_id in sequence (622). The process of steps 621 and 622 is repeated until the last Content_id (623). In operation 630, the same information may be confirmed by comparing Annotation_object_data for each same Content_locator. To this end, an Annotation_object_data may be sequentially selected for the same Content_locator (631), and the count may be accumulated for the Content_locator having the same Annotation_object_data (632). The process of steps 631 and 632 is repeated until the last Content_locator (633). In operation 640, the number information related to annotations may be calculated for each digital content by searching for duplicate information based on annotation data by the above procedure.

Furthermore, in the present invention, the number of annotations for each digital content is provided by the annotation providing code of the e-book according to a request of a user or an administrator who has authority to manage digital content. To this end, the user terminal or server system may provide a UI for checking the number information related to the annotation.

For example, a UI capable of checking the number of annotations for each chapter in terms of content composition, such as an individual chapter, may be provided. As shown in FIG. 7, a graph showing the number of annotations generated from the content of each chapter for each chapter on a page 710 providing a list of chapters of digital content (hereinafter referred to as an annotation graph) ( 720). In this case, a menu 721 for specifying a range of annotations is provided on the UI screen on which the annotation graph 720 is exposed, and if a range for the number of annotations is specified from a user or an administrator, The number of annotation data may be represented in the annotation graph 720 only for the chapter. In other words, the annotation graph 720 may be configured by selecting only the corresponding content through the search expression 721 for the number of annotations by the annotation providing code of the e-book. In addition, the annotation graph 720 may be expressed in a form in which at least one chapter having a large number of annotations is recommended to an administrator or a user based on the number of annotations for each chapter. For example, the bar 722 of the chapter having the largest number of annotations in the annotation graph 720 may be expressed in a form different from that of other chapters (eg, expressed in a separate color). That is, when a question about digital contents is to be asked in the curriculum, a plurality of students may automatically extract items that are annotated and provide a UI environment in which the items are recommended to the questionnaire (ie, the administrator). In addition, in the UI environment providing the annotation graph 720, when a user or an administrator clicks at least one annotation bar, the UI link may support a page link for moving to a page displaying a chapter content corresponding to the selected bar.

Accordingly, the user terminal and the server system according to the present invention can provide a UI environment capable of confirming the number of annotations for each digital content based on the annotation function and extracting items in which a plurality of annotations are created from the digital content. .

The method of generating, managing, and expressing the annotation described above with reference to FIGS. 1 to 7 may include shorter operations or additional operations. In addition, more than one operation may be combined, and the order of operations may be changed.

Hereinafter, embodiments of the devices will be described in relation to a method for generating, managing, and expressing the above-described annotation. FIG. 8 is a block diagram illustrating an e-book service system (ie, a server system) that provides an e-book service for digital content according to an embodiment of the present invention.

As illustrated, the e-book service system includes an authentication management module 810, a user profile database 811, a content management module 820, a content database 821, an annotation management module 830, and an annotation information database 831. , Discussion management module 840, discussion information database 841, audience measurement module 850, and audience information database 851. The authentication management module 810, the content management module 820, the annotation management module 830, the discussion management module 840, and the audience measurement module 850 may be configured separately or may be integrated modules. In addition, each module may perform an independent function or may be operated in a form that is dependent on at least one other module. The user profile database 811, the content database 821, the annotation information database 831, the discussion information database 841, and the audience information database 851 may be individual database systems or integrated into one database system.

The authentication manager 810 may store and manage general personal information related to the user in the user profile database 811. The personal information may include profile information and authentication information of the user registered in the system in relation to the e-book service. The authentication management module 810 may check the user's identity based on the authentication information when the user's identity is required, and may store and edit the profile information according to the user's request.

The content manager 820 may store and manage the electronic book-based digital content in the content database 821. The content management module 820 may maintain digital content stored in the content database 821, and may be in charge of continuous management of updates and the like. The content management module 820 may support a search function so that a user may search for digital content through the content database 821. The content management module 820 may provide a viewer function for digital content by providing digital content desired by the user to the user terminal according to a request of the user through the user terminal. In this case, the content management module 820 may provide a content layer in which digital content is rendered to the user terminal. The content management module 820 may search for information on the Internet by interoperating with a content server 821 and a search server that provides a search engine for all information on the Internet. For example, the content management module 820 recognizes an object selected by a user in digital content through a user terminal, and then provides a search function of searching for information on the Internet using the recognized object as a keyword and providing the search result. can do.

Annotation manager 830 may provide annotation functions for digital content and maintain and manage annotation data related to the digital content. The annotation function may collectively refer to any way a user expresses additional information in digital content. For example, all of the data may be annotation data when a variety of application add-ons, such as a bookmark function, an underline, an important mark, and a memo are additionally applied to the original content. Accordingly, the annotation management module 830 recognizes the object selected by the user through the user terminal, generates annotation data applying the annotation application to the object according to the user's request, and associates the annotation data with the user. 831 can be stored. Thereafter, the annotation management module 830 may render the annotation data on the annotation layer overlaid on the content layer and provide the annotation data to the user terminal. Accordingly, the user may select a predetermined object from the digital content in use through an object selection function and then apply a function such as bookmark, underline, important mark, or add a memo to the corresponding object.

Furthermore, the annotation management module 830 may calculate the number information related to the annotation for each digital content by using the annotation data. For example, the annotation management module 830 may count the number of annotation data generated from the same content based on the ID value Content_id of the digital content connected to the individual ID Annotation_id of the annotation data. As another example, the annotation management module 830 may divide the content of the digital content based on a location value (Content_locator) of an object linked to an individual ID (Annotation_id) of annotation data (for example, a paragraph or a chapter). Etc.), the number of annotation data generated from the same item can be counted. As another example, the annotation management module 830 may count the number of annotation data generated for the common object based on the actual data (Annotation_object_data) of the object connected to the individual ID (Annotation_id) of the annotation data. Accordingly, the annotation management module 830 may provide a UI for checking the number of annotations for each content for the user or the administrator. For example, the annotation management module 830 may recommend at least one item to a user or an administrator based on the number of annotation data generated from each item among the items in which the content of the digital content is divided. As another example, the annotation management module 830 may provide a graph indicating the number of annotation data generated by each item for each item of digital content, and further, the user or administrator may add the annotation data to the number of annotation data. If a range is specified, a graph indicating the number of annotation data can be provided only for the items corresponding to the specified range. As another example, the annotation management module 830 may display a bar of an item having the largest number of annotation data in the annotation graph in a different form from that of another item, or when a user or an administrator selects a specific bar, an item corresponding to the selected bar is displayed. You can provide a function that takes you to a page that displays content. Accordingly, the annotation management module 830 may provide a UI environment in which the number of annotations can be checked for each digital content based on the extracted items from which a plurality of annotations are created.

The discussion manager 840 may provide a discussion function (ie, a sharing function) with respect to the digital content, and maintain and manage the discussion information related to the digital content through the discussion information database 841. The discussion function may collectively refer to all community methods of sharing mutual opinions among a plurality of users via digital content. For example, the user can register his or her own opinion or query about the digital content being used through the discussion function in the discussion information database 841, and thus, the discussion management module 840 to comment with a friend or other person. You can share a message or get a response to a query. To this end, the discussion management module 840 receives discussion content about a predetermined object from the user terminal, and transfers the discussion content received from the user terminal to a corresponding user terminal based on user profile information of the authentication management module 810. Can provide.
