Abstract:
A device and a method for allocating subjects or fields in an information search system are provided to search information by allocating the subjects or the fields automatically based on taxonomy, or based on tags or folksonomy when a thesaurus is not constructed. A search engine(41) searches information from documents based on an index corresponding to a query or the document, and a database(42) stores and manages the information searched by the search engine. A thesaurus matcher(43) allocates a subject or a field to the document by extracting the index from original document stored in the database and performing thesaurus matching based on the index. A taxonomy processor(44) allocates the subject based on terminology by extracting the terminology from a definition sentence stored in the database and allocates the field by using taxonomy. A tag processor(45) extracts a tag from a web document having the tag among the documents stored in the database and allocates the subject by using the extracted tag. A folksonomy processor(46) extracts the tag from the web document, allocates the subject by using the extracted tag, and allocates the field by using the folksonomy.
Abstract:
온톨로지에 모델링된 각각의 개체명의 클래스와 클래스의 속성을 분류에 활용하는 온톨로지 기반의 문서 분류 방법 및 그에 적합한 장치가 개시된다. 온톨로지 기반의 문서 분류 방법은 각 범주에 속하는 문서들의 특성을 온톨로지로 표현하기 위해서 동일 범주에 속하는 문서들에서 공통으로 발생하는 개체들의 종류와 속성(property), 속성 관계(property relation) 을 추출하고 이를 추상화(abstraction)하여 온톨로지를 모델링하는 온톨로지 모델링 과정; 분류하고자 하는 문서로부터 개체명을 인식하는 개체명 인식 과정; 전체 범주를 대상으로 문장 분석을 통해서 개체명 사이의 관계 정보를 추출하는 개체 관계 추출 과정; 문서에서 추출된 개체명과 관계 속성을 각 범주별 온톨로지와 비교해서 개체-클래스, 개체-속성-개체로 매핑(mapping)하는 인스턴스 필링 과정; 및 필링된 클래스, 인스턴스간 관계, 클래스 속성의 가중치를 고려해서 상기 분류하고자 하는 문서에 가장 적합한 온톨로지를 선택하고, 해당 온톨로지의 분야를 분류하고자 하는 문서의 분야로 결정하는 문서 분야 결정 과정을 포함한다.
Abstract:
PURPOSE: A device for predicting a technology awareness change and a method thereof are provided to increase efficiency through the selection and concentration of core competencies by minimizing the trial and error of research and development and overlapped research prevention. CONSTITUTION: A technology statistic information extracting unit(110) analyzes documents stored in a multiple literature providing device to extract statistic information about specific technology. A technology awareness calculating unit(120) obtains a credibility value of a document from which the specific technology is extracted, a location information value in the document from which the specific technology is extracted, and an importance value of the specific technology in the document based on the statistic information in order to obtain an awareness value of the specific technology according to each document. An awareness change predicting unit(130) collects awareness values by year, obtains an average value by year, and predicts an awareness change speed of the specific technology. [Reference numerals] (100) Technology awareness change predicting device; (110) Technology statistic information extracting unit; (120) Technology awareness calculating unit; (130) Awareness change predicting unit

Abstract:
PURPOSE: An apparatus and a method for predicting development speed of technology are provided to determine stages and development speed in a technology life cycle of a specific technology which is not included in the technology life cycle using the Delphi method. CONSTITUTION: A quality set generating module(130) computes the quality value of technologies included in the technology lifecycle by the search of the bibliographic database and produces quality value sets classified into the technologies using the quality value. A correct quality set generating module(140) computes the common value of the quality sets of the technologies belonging to the same stage in the technology life cycle and produces the correct quality set classified into the steps. A chronicle stage determining module(150) acquires quality information about the defined qualities by the search of the bibliographic database.
Abstract:
PURPOSE: An apparatus and method for searching an instance path based on an ontology schema are provided to quickly find complex associative relation by searching a class based inter-instance path. CONSTITUTION: A UI(User Interface) unit(208) receives two or more keywords from a user. An instance pair generator(210) creates an instance pair by obtaining instances of the keyword from an ontology instance database(202). A class pair extractor(212) extracts class pair corresponding to the instance pair from the ontology instance database. An instance path searcher(216) replaces a start and an end class of the ontology schema path into a first and a second instance and searches instance paths which are connected to the first and the second instances.
Abstract:
PURPOSE: An ontology based instance identification system and a method thereof are provided to improve the accessibility of information through deduction between meanings by generating an ontology instance which a URI(Uniform Resource ID) is given when converts data of an RDBMS(Relational Database Management System) into the instance of an OWL(Web Ontology Language) ontology. CONSTITUTION: An ontology register registers an ontology consisting of a class, an attribute, the relationship information between the classes in an ontology database(810) of a database unit. If a target instance is inputted, a class-instance linker(400) selects and connects the class which the instance is allocated. A reference/additional information obtainer(600) obtains the information required for the identification of the target instance. A controller(500) identifies the target instance from the ontology database by using the information.
Abstract:
PURPOSE: An ontology based sameAs management system and a method thereof are provided to share the set up including generation or deletion of a sameAs relation about ontology instances with different ID by synchronizing sameAs management servers with a equal level on a real time basis and synchronizing the high and lower level sameAs management server. CONSTITUTION: Storage(111) stores the set up information including generation or deletion of a sameAs relation and the relationship information for checking the sameAs relation. A relation turnaround unit(113) checks the sameAs relation of an instance corresponding to a query language of a user and returns the relation of a sameAs management server. A query generating unit(115) generates an SPARQL(Simple Protocol and RDF(Resource Description Framework) Query Language) query which the instance within a list is reflected. A result generating unit(117) generates a result corresponding to the SPARQL query.
Abstract:
PURPOSE: A system and a method for SPARQL-query processing using the parameterized-SPARQL-query in based DBMS are provided to reduce semantic web service query time thereby improving service quality. CONSTITUTION: A parameter list generator creates a parameter list from SPARQL(SPARQL Protocol and RDF(Resource Description Framework) Query Language) query. A transforming method(200) makes a PS(Prepared Statement) object correspond to at least one SQL statement, then stores the PS object, wherein the PS object converts the SPARQL query sentence into a SQL(Structured Query Language) statement. A Database Management System(400) outputs result of inquiry using a PS object and the parameter list which is stored corresponding to the converted SQL statement.
