Semantic Search Method and System for Supporting Meaningful Grouping and Visual Navigation Based on Bibliography Metadata}

The present invention relates to a search service method and system, and to applying bibliographic records (FRBR) ontology modeling to bibliographic metadata handled by a library, through semantic grouping based on the meaning of bibliographic metadata. Retrieval service method and system for visually and graphically navigating the list of semantic linking information for each grouping item with (signature) and its author, subject, related book, etc. It is about.

Search systems used in internet bookstores and libraries provide classification information such as catalogs of books, summary information, and Korea Decimal Classification (KDC) based on bibliographic metadata. Such a search system may similarly provide various materials similar to a search word in an internet shopping mall or an academic information providing site.

However, in the existing general search system, a limited range of search results are provided with reference to database resources, and navigation of the search results is not easy. For example, in a general search system, a full text search is performed based on all resources other than bibliographic metadata for search terms, which not only has a problem that requires a lot of search time and results, but also results in a text form. Since the list of semantic associations is not managed and the grouping of semantic associations is not managed, the provision of semantic linking information list is temporary, and the search results are not visually represented in a graphical form. Uneasy.

Accordingly, an object of the present invention is to solve the above-described problems, and an object of the present invention is to apply the FRBR (Functional Requirements for Bibliographic Records) ontology modeling to the bibliographic metadata handled in a library, thereby identifying the meaning of each element of the bibliographic metadata. Through the semantic grouping on the basis, the list of semantic linking information for each grouping item with the semantic linking of the work (signature) and the author, subject, related book, etc., in the form of text and visually To provide a search service method and system for navigation.

First, to summarize the features of the present invention, the method for the semantic search service in the bibliographic metadata-based search service system according to an aspect of the present invention for achieving the object of the present invention, the user terminal to the database; Receiving a search term using a search term auto-completion function in a bibliographic metadata category of stored resources; Storing a search result including bibliographic metadata of resources searched for the search word in storage means; Classifying the search result resources into a plurality of grouping items based on a match degree of a keyword appearing in the bibliographic metadata of each resource so that the resources of the search result have a semantic link between bibliographic metadata elements; Extracting a related resource list belonging to each of the plurality of grouping items; And graphically displaying the plurality of grouping items in a predetermined area of a user terminal screen, while displaying related resource lists and corresponding bibliographic metadata elements belonging to the plurality of grouping items in other areas of the user terminal screen as text. It includes a step.

If any one of the plurality of grouping items is selected as a click in an area of the screen that graphically displays the plurality of grouping items, a screen for displaying the related resource list and the corresponding bibliographic metadata element for the item as the text. Display at the top of the area.

In the area of the screen that visually displays the plurality of grouping items, the method of displaying the plurality of grouping items is a method of arranging one item in a center and the remaining items around the circle of the center.

The item selected by the click moves to the center, the items around the circle move one space in a clockwise or counterclockwise direction, and the item at the center can return to the space around the circle.

A corresponding resource list for any one of the items around the circle is displayed around an area of the screen that graphically displays the plurality of grouping items.

The corresponding resource list for any one of the items around the circle is displayed at the bottom of an area of the screen which visually and graphically displays the plurality of grouping items.

The bibliographic metadata elements include the name of the work, the name of the author, the type of material, the genre, the language, the form of expression, the abstract, the table of contents, the note, the subject, the classification, the related information, the identifier, the location of the collection, the restrictions of use, the publisher and the publication. Date, or subject to use.

The plurality of grouping items may include a work, a person responsible for the work, an expression person, a form person, a related subject, a related book, or a related author.

In addition, a bibliographic metadata based search service system according to another aspect of the present invention includes a database storing resources; A search engine extracting a search result including bibliographic metadata of resources searched for the search term by inputting and searching a search term with a search term auto-completion function in a bibliographic metadata category of resources stored in the database; A search result storage unit which stores the search result; The resources of the search result are classified into a plurality of grouping items based on the degree of coincidence of keywords appearing in the bibliographic metadata of each resource so that the resources of the search result have a semantic link between the bibliographic metadata elements. A control unit for extracting a list; A visual navigation unit visually and graphically displaying the plurality of grouping items in a predetermined region of a user terminal screen; And a text navigation unit displaying, in text, a list of related resources and corresponding bibliographic metadata elements belonging to the plurality of grouping items, respectively, in different areas of the user terminal screen.

According to the search service method and system according to the present invention, by applying the FRBR ontology modeling through the semantic grouping based on the meaning of each element of the bibliographic metadata, the work (signature) and its author, subject, related books, etc. The list of semantic association information for each grouping item with semantic association can be navigated visually and graphically along with the text form.

Accordingly, the information that appears to be a simple list can be grouped semantically, and the search results can be provided by various methods, and the responsible subject, expression subject, form subject, related subjects, related books, related authors, etc. By allowing the user to browse through the visual graphic, an easy search service can be provided until the user finds the desired information.

In some cases, the computer-readable recording medium may be read by a computer-readable recording medium. As an application program in the form of code, each component may be implemented to execute a corresponding function.

FIG. 2 is a diagram illustrating a case where the search service system of FIG. 1 is implemented as a server in a wired / wireless network environment.

As shown in FIG. 2, the search service system 100 according to an embodiment of the present invention includes a server connected through a wired / wireless network (for example, the Internet, a WCDMA mobile communication network, a WiBro network, etc.) to connect to a wired / wireless network. FRBR (Functional Requirements for Bibliographic Records) ontology modeling is applied to bibliographies that are handled in book-related fields such as libraries and Internet bookstores on users' terminals (eg, desktop PCs, notebook PCs, iPhones, PMPs, etc.). In addition, through semantic grouping based on the meaning between bibliographic metadata elements, a list of the semantic linking information for each grouping item with a semantic link between the work (signature) and its author, subject, and related books is presented in text format. In addition, the service can be visually and graphically navigated.

To this end, the controller 110 of FIG. 1 drives predetermined wired / wireless communication means (not shown) to communicate with wired / wireless according to standards such as the Internet, WCDMA, IMT-2000, WiBro (mobile Internet), etc. through wired / wireless communication. The user interface 120 may support the user to input necessary data such as search terms and options input by the user on the wired / wireless network and transmit data such as search results generated by the system 100 to the user terminal. Can be supported.

3 or 4, in the search service system 100 according to an embodiment of the present invention, the meaning based on the meaning of the bibliographic metadata elements by applying FRBR ontology modeling to a search result of a search word input by a user. Through the formal grouping, a visually schematic form 220 of the semantic linking information for each grouping item with the semantic linking of the work (signature) and the author, subject, related book, etc. together with the text format 210 is provided. You can also navigate with. Accordingly, instead of showing the search results in a simple list as before, the search results can be provided by semantically grouping them in various ways, and are responsible for the work, the subject of expression, the subject of form, the related subjects, and related books. By visually viewing each grouping item such as and related authors, it is possible to provide an easy search service until the user finds the desired information about the book.

Here, the terminal for the user to use the services of the search service system 100 is a notebook PC, desktop PC, Palm Personal Computer (PDA), Personal Digital Assistant (PDA), smart phone (Smart phone) , WAP phone (Wireless application protocol phone), mobile game-station (mobile play-station) and the like, as well as cellular phone (Cellular phone), PCS phone (PCS phone :) that supports mobile communication protocols, such as WCDMA It refers to all electronic devices that can communicate using wired / wireless networks such as Personal Communications Services phone) and synchronous / asynchronous IMT-2000 (wireless mobile communication).

Hereinafter, a flowchart of FIG. 5 will be referred to for describing an operation of the search service system 100.

First, the database 111 stores and manages resources for various works (signatures) according to a certain classification scheme such as Dudey Decimal Classification (DDC) or KDC. The resources may be in the form of documents, movies, recordings, images, video files, databases, or text data formats, each of which has a title, author name, material type, genre, language, presentation form, abstract, table of contents, Bibliographic metadata elements such as notes, subjects, classifications, related information, identifiers, collection locations, restrictions on use, issuer, issue date, or useee are mapped and managed.

As such, the resources managed in the database 111 are interspersed with, for example, certain works and expressions embodied by various expression subjects such as translations, movies, images, sounds, performances, and excerpts, and for each expression. Form implementations implemented by various form entities such as VOD, DVD, books, e-books, PDFs, files, slides, CDs, and tapes are scattered, and they need to be grouped semantically to provide search results in various ways. In addition, each grouping item such as the subject responsible for the work, the subject of expression, the subject of form, the related subject, the related book, the related author, and the like must be visually viewed to enable easy searching.

When the user inputs a search word for book search through the terminal screen, the system 100 may input a search word by the search word auto completion function as shown in FIG. 6 supported by the search engine 130 (S110). In this case, the search engine 130 may receive a search word as a search word auto completion function in the bibliographic metadata category of the resources stored in the database 111. In other words, whenever a user enters text into the search box, the user can be provided with an example search term based on bibliographic metadata including the input text. You can enter the completed search word.

As such, when the search word is input by the search word auto-completion function, the search engine 130 searches the database 111 for the input search word, extracts the search result including the bibliographic metadata of the searched resources, and stores the search result. Stored in the unit 131 (S120). The search engine 130 may search for resources related to the input search word in the database 111 based on a semantic scheme.

As such, when the search result including the bibliographic metadata of the searched resources is stored in the search result storage unit 131, the control unit 110 controls the bibliographic meta data of each resource such that the resources of the search result have a semantic link between the bibliographic metadata elements. Based on the degree of match of the keyword appearing in the data, it is classified into a plurality of grouping items (S130), and a related resource list (see 230 of FIG. 3) belonging to the classified plurality of grouping items may be extracted (S140). Here, the plurality of grouping items may include a work, a person responsible for the work (for example, the author), an expression subject (for example, the author of the expression), a form subject (for example, the publisher), a related subject, a related book, Or related authors, etc. (see 220 of FIG. 3).

Based on the bibliographic metadata, the semantic linkage information extraction system applying FRBR (Functional Requirements for Bibliographic Records) thematic ontology modeling to the bibliographic metadata. It can be applied to technology such as normalization processing system of index extraction, weighted grouping method based on individual social information and other elements, and connection information extraction system based on ontology triple relationship. For example, all the various information in the bibliographic metadata can be searched to find keywords that appear at a certain frequency or more, and resources whose keywords match more than a certain number of times can be grouped together in the same group. Elements (work name, author name, type of material, genre, language, form of expression, abstract, table of contents, note, subject, classification, related information, identifier, collection location, restrictions on use, publisher, publication date, or use) A certain weight may be assigned according to the subject).

After the grouping is performed as described above, the visual navigation unit 150 may visually display a plurality of grouping items in a predetermined area (refer to 220 of FIG. 3 or 4) of the user terminal screen (S150). The navigation unit 140 texts a list of related resources and corresponding bibliographic metadata elements (one or more metadata elements) belonging to a plurality of grouping items, respectively, in another area of the user terminal screen (see 210 of FIG. 3 or 4). It becomes possible to display (S160).

The controller 110 may control to interwork between the navigation of the grouping items visually displayed in area 220 and the text navigation in area 210 (S170). For example, when any one of the plurality of grouping items is selected as a click in the area 220 of the screen that visually displays the plurality of grouping items, it corresponds to the top portion of the screen area 210 that is displayed as text. You can control to display a list of related resources for the item and the corresponding bibliographic metadata element.

Here, in the area 220 of the screen that visually displays a plurality of grouping items, a method of displaying a plurality of grouping items is based on one item and a circle around the center under the control of the controller 110. This can be done by placing the remaining items.

In the area 220 of the screen that visually displays a plurality of grouping items, the item selected by clicking moves to the center as above, and the items around the circle move by one space in the clockwise or counterclockwise direction, and in the center. As described above, after the items around the circle are moved one by one as described above, the controller 110 may control the items to return to the blanks around the circle.

In addition, an area 220 of the screen that graphically displays a plurality of grouping items, corresponding to the relevant resource list 230 for any one item among the items around the circle (eg, the bottommost item). Control by the control unit 110 is possible to display around, for example, a lower end of 230.

As shown in FIG. 7, the text navigation area 210 does not simply display a search result in a text table format as before, but collects bibliographic information that is meaningful and morphologically related to each item element and its expression. As a navigation method, a list of related resources belonging to each grouping item and a corresponding bibliographic metadata element (one or more metadata elements) may be displayed as text. For example, based on the original work (W), not only describes the relevant subject and information of the responsible person (author), but also translations, trials, films, images, sounds, performances, and excerpts related to the original work. By linking various expressions (E: Expression), etc., you can browse bibliographic information such as language, original language, expression subject (author), abstract, cycle, table of contents, and target audience. Each representation is grouped together with the morphological description of the entity (M: Manifestation) embodied in various media forms that can be accessed by real users, ISBN, price, subject of implementation (type of entity: publisher or publisher), and year of publication. You can also browse. If a bibliography exists among bibliographic metadata components, the bibliography may be grouped together to provide more access points.

As described above, in the present invention, in addition to the work (the book), the core bibliographic component among the navigation information shown in the text, the person or organization information on the responsible person (author), the expression subject, the form subject, and the original work as a standard Visualize the related topics list, related books list, and related author list that have semantic linkage with the information described in this section. The visual scheme maintains a circular shape and takes a balanced rotation method. As the selected object is moved to the center with a click, the related information is changed and the step-by-step reading can be performed, and history back function is also provided. can do. The list of related resources instead of single entity information may be provided together in the form of a list by moving to the bottom.

The functions used in the methods and apparatus disclosed herein can be embodied as computer readable code on a computer readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, hard disk, removable storage, and also carrier wave (for example, transmission over the Internet).
