The present invention relates to a researcher's performance information construction and service system through ontology-based bibliographic analysis, and a method and method and a recording medium storing a computer program for the method. Constructing researcher's performance information and service system, method and method by using ontology-based bibliography analysis that extracts references from existing citation indexes and assigns citation information between researchers using ontology and reasoning The present invention relates to a recording medium storing a program.

The citation index has been studied by several indicators, including the Science Citation Index (SCI) developed by ISI in the United States. However, these indicators are the result of manual analysis of references, and their role is limited to the citation of documents. This information only provides a limited service of how much a particular document is cited and how influential it is.

Therefore, the present invention has been made to solve the above problems, an object of the present invention is to build a bibliographic information for the registered literature, and to automatically extract the references in the literature to compare it with the existing bibliographic information DB, Reflecting citation information between documents in ontology and analyzing citation relationship between researchers using author information, constructing researcher's performance information through ontology based reference analysis that can be used for various applications including researcher network presentation, manpower recommendation service, and To provide a service system and its method.

In addition, another object of the present invention is to provide a recording medium storing a computer program for the researcher performance information construction and service method through the ontology-based reference analysis.

In order to achieve the above object, the researcher's performance information construction and service method through ontology-based bibliography analysis according to the present invention includes (a) inputting a thesis file and constructing bibliographic information by using manual or information extraction techniques. Storing the bibliographic information in the bibliographic information DB through a bibliographic information DB addition process; (b) identifying a bibliography region and extracting bibliography from the article contents extracted as text after filtering the article file; (c) extracting the bibliography and performing a bibliographic information search comparing the bibliographic information with the bibliographic information in the bibliographic information DB; (d) linking a currently inputted document to a document having a matched bibliographic information when the bibliographic information is found in the bibliographic information DB; (e) adding the connection information in the step (d) to the bibliographic information DB, generating ontology-based bibliographic information triples through ontology reference, and updating the knowledge with extended knowledge by applying inference rules; And (f) obtaining citation information connected to a specific human resource through inference using the ontology-based bibliographic information triples and providing a service through processing inference results.

The bibliographic information preferably includes all the main information for describing the article including ID, article title, author, source, and year.

In the information extraction technique, it is preferable to extract the information including the journal, conference name, and year including the author by recognizing the bibliographic information extraction region and the entity name.

In the object name recognition method, it is preferable to use an object name recognizer that recognizes specific object names and their types in a document or a sentence by using an object name dictionary including each object name type information.

The researcher performance information construction and service method, in the step (a) it is preferable to further include a step of manually or automated to give a Uniform Resource Identifier (URI), which is a major element of the ontology.

The granting of the URI preferably includes a manpower URI grant, a URI grant for the document itself, a URI grant for source information and affiliation information.

The method of manually assigning the URI may be performed by comparing the information including the co-author's author's email, author's Korean name, author's English name, author's organization, author's affiliation department, and year of publication to the same human resource. It is preferable to assign an identifier value of the determined manpower to the manpower URI.

In the method of automatically assigning the URI, a person who is determined to be the same author by comparing the same co-author, author's email, author's Korean name, author's English name, author's organization, author's affiliation, and publication year in the existing registered bibliographic information DB. It is desirable to assign the URI to the matched author in the currently entered bibliographic information.

If matching fails in the URI assignment operation, it is preferable to assign a new personnel URI according to a predefined personnel URI generation rule.

In the step (c), it is preferable to use a title of 'References' or a technique of recognizing a reference form including an author, a title, and a year of origin.

When searching for bibliographic information in the step (d), it is preferable to check whether the title, author, source, and year match.

In addition, the recording medium storing the computer program for the researcher performance information construction and service method through the ontology-based reference analysis according to the present invention for achieving the above object is any one of claims 1 to 11. It features a recording medium that stores computer programs for researcher performance information construction and service methods by analyzing the ontology-based bibliography.

Hereinafter, referring to the accompanying drawings, a method of manually extracting a reference from an existing citation index that analyzes a reference manually and assigns citation information only between documents, and provides citation information between researchers using ontologies and inferences. Explain.

First, the researcher's performance information construction and service system according to the present invention uses the ontology of the form shown in FIG. Ontology is a representation of a conceptual system within a specific domain and consists of the concepts and the properties that connect them. In addition, it may be referred to as a concept network having a graph structure in which concepts are connected according to domains and services.

The citation index has been studied by several indicators, including the Science Citation Index (SCI) developed by ISI in the United States. However, these indicators are the result of manual analysis of references, and their role is limited to the citation of documents. This information only provides a limited service of how much a particular document is cited and how influential it is.

The present invention is characterized in that it extends to the author, not limited to the literature only to overcome such service limitations. However, there is no way to provide accurate author-specific citation information unless the problem of the same name for the authors of the literature is solved. Therefore, in the present invention, the ontology is modeled and instances in the ontology are represented by an identifier called a Uniform Resource Identifier (URI), thereby ensuring that each author is unique. In addition, inference rules can be used to give citations between documents, and to cite relationships among authors. As a result, the researcher's performance information construction and service system according to the present invention provides an accurate index for analyzing the researcher's performance information by using the citation relationship network among the authors constructed by the above method, and thus recommends experts, organizes the researcher's network, and overseas experts. It can be used for various manpower related services such as securing.

Example

1 is a flow chart of the researcher performance information construction and service system according to a preferred embodiment of the present invention.

When a manuscript file is input, first, bibliographic information (main information that can describe the manuscript such as ID, title, author, source, and year) is constructed by using manual or information extraction technique (step S101).

In the case of using the information extraction technique, first, the bibliographic information extraction area is recognized, and the journal, conference name, and year including the author are extracted based on the named entity recognition. At this time, in order to recognize the entity name, an entity name dictionary should be constructed first, and each entity name type (eg, person) information should be included. The entity name recognizer uses this entity name dictionary to recognize specific entity names and their types in the document or sentence. This information extraction technique is also used for bibliographic information extraction (step S109).

The bibliographic information thus constructed is stored in the bibliographic information DB via the bibliographic information DB addition (step S103). In this process, we assign URI which is a major element of ontology. This can be done manually or by automation.

In this case, a method of manually assigning a URI may be performed by using a professional human resources service system such as the 'National Science and Technology Manpower Information System' (http://www.hrst.or.kr/). It is preferable in terms of information sharing. Of course, it is also possible to assign a new using a separate URI management system.

The method of manually assigning a URI may be determined by comparing the author's e-mail, author's Korean name, author's English name, author's organization, author's affiliation department, year of publication, etc. Assigns the identifier of the person being created as a person URI.

Next, a method of assigning a URI using an automated technique uses a technique of searching for and comparing a person with the same name in a previously registered bibliographic information DB. That is, comparing the same co-author, author's email, author's Korean name, author's English name, author's organization, author's affiliation, and publication year in the existing registered bibliographic information DB, matching the URI of the manpower determined to be the same author within the currently entered bibliographic information To the author.

At this time, when matching fails in the URI assignment operation, new personnel URIs are assigned according to a predefined personnel URI generation rule. In order to provide a wider range of services, not only manpower URIs but also URIs for the documents themselves, URI information for source information and affiliation information are provided.

The process for assigning the citation information begins with document filtering of the article file (step S105). In this case, the document filtering refers to an operation of extracting text from a format document, such as Korean, MS Office, or the like.

Then, the reference region is identified from the content of the article extracted as text through the document filtering, and the references are extracted (step S107).

The bibliography area uses a title 'References' or a technique for recognizing a bibliography format (eg, author, title, source (year), etc.). This technique is the same as the technique of automatically performing bibliographic information construction (step S101).

Then, a bibliographic information search (step S111) is performed, which extracts bibliographic references from the article and compares them with bibliographic information in the bibliographic information DB.

At this time, in the reference bibliographic information search (step S111), in order to determine the same reference, check whether the title, author, source, year match. When comparing titles, normalization of alphabetic characters (e.g., ignoring capitalization), white space (e.g., tab characters, spaces, etc.) should be preprocessed.

Then, when matching bibliographic information is found in the bibliographic information DB (step S113), the currently input literature is connected with the bibliographic information having the matching bibliographic information (step S115).

Then, the connection information is added to the bibliographic information DB (step S117), and this connection information is later expressed as a property through an ontology reference (step S119).

Here, the ontology reference (step S119) generates ontology-based bibliographic information triples (composed in the form of <Subject, Predicate, Object> in a manner of expressing knowledge in the semantic web) for use as inference data for providing a service. The process of doing.

Then, the knowledge generated through the ontology reference is updated to more expanded knowledge through the application of inference rules (step S121). This process may be performed in the bibliographic information DB adding step (S103), and is performed in this step if it is to be processed through the inference rule.

As shown in FIG. 4, the extended ontology-based instances as shown in FIG. 5 are obtained from the ontology-based instances as shown in FIG. 3 by applying an inference rule that gives a citation relationship between the authors to the existing ontology.

Then, directly or indirectly information is obtained through inference using the ontology (step S125).

Through the inference (step S125) to obtain the citation information (e.g., citation, quotes, citations, number of citations, etc.) associated with a specific personnel to provide a service through processing the inference result (step S127) ( Step S129).

In the inference result processing (step S127), the information obtained through inference is processed to obtain various statistical information. For example, to obtain statistical information about how many times a specific citation is cited from how many people, each of these pieces of information must be combined. The researcher's performance information construction and service system according to the present invention provides a method for obtaining qualitative and not quantitative information of which researcher has performed a materially important research by providing such citation-related information from various angles.

Therefore, the researcher's performance information construction and service method of the present invention builds bibliographic information on the registered literature, automatically extracts the references in the relevant literature, compares them with the existing bibliographic information DB, and compares the citation information between the documents. By reflecting on ontology and analyzing citation relationship among researchers using author information, it can be used for various applications including researcher network presentation and manpower recommendation service.

As described above, according to the ontology-based bibliographic analysis of the present invention, the researcher's performance information construction and service system, and a method and a recording medium storing a computer program by the method, construct bibliographic information for the registered literature. In addition, it automatically extracts references from relevant documents and compares them with existing bibliographic information DBs, reflects citation information between documents in ontology, and analyzes citation relationships among researchers using author information, suggesting researcher networks and recommending personnel. It can be used for various applications.

In addition, it can be used in various application fields such as recommending experts and grasp trends of personnel, which require qualitative evaluation by researchers by constructing citation information for researchers that go beyond reference analysis and citation information establishment based on existing manual work. .

In addition, it is possible to construct semantic web-based service system by using ontology and inference, and to lay the foundation for resolving information ambiguity such as manpower and literature by actively utilizing URI.

In addition, it is possible to analyze the research results at the institutional and departmental levels by using related information such as not only the researcher but also the affiliated organization and department.
