(EN) SYSTEM AND METHOD FOR A RELATED SEARCH SERVICE BASED ON AN RDF NETWORK
(FR) SYSTÈME ET PROCÉDÉ DESTINÉS À UN SERVICE DE RECHERCHE CONNEXE BASÉ SUR UN RÉSEAU RDF

Abstract
(EN) The present invention relates to a system and method for a related search service based on an RDF network, which searches for subjects or objects that have the same predicates on the basis of an RDF network and provides the found subjects or objects as related data, wherein the RDF network is configured by extracting subjects, predicates, and objects which are elements of an RDF model from a text document composed of unstructured sentences which do not have structured forms and by distinguishing entities according to whether or not the entities are semantically the same. The method for a related search service based on an RDF network according to the present invention comprises the steps of: (a) extracting subjects, predicates, and objects from a text document composed of unstructured sentences which do not have structured forms; (b) generating RDF models that are each composed of one of the extracted subjects, one of the extracted predicates, and one of the extracted objects; (c) comparing the RDF models with each other to determine whether or not they semantically conflict with each other; (d) constructing an RDF network by separating the RDF models when they conflict with each other and by merging the RDF models when they do not conflict with each other; and (e) providing a service for searching for the subjects or objects that have the same predicates on the basis of the constructed RDF network.
(FR) La présente invention concerne un système et un procédé destinés à un service de recherche connexe basé sur un réseau RDF, qui recherche des sujets ou des objets ayant les mêmes prédicats sur la base d'un réseau RDF et qui met à disposition les sujets ou objets trouvés sous la forme de données connexes, ledit réseau RDF étant conçu par l'extraction des sujets, des prédicats et des objets qui constituent les éléments d'un modèle RDF à partir d'un document texte composé de phrases non structurées qui n'ont pas de forme structurée, et par une distinction des entités en fonction de leur ressemblance ou de leur différence sur le plan sémantique. Ledit procédé selon l'invention, qui est destiné à un service de recherche connexe basé sur un réseau RDF, consiste : (a) à extraire des sujets, des prédicats et des objets à partir d'un document texte composé de phrases non structurées qui n'ont pas de forme structurée; (b) à générer des modèles RDF dont chacun est composé de l'un des sujets extraits, de l'un des prédicats extraits et de l'un des objets extraits; (c) à comparer les modèles RDF les uns aux autres afin de déterminer s'ils sont en conflit sur le plan sémantique; (d) à élaborer un réseau RDF par la séparation des modèles RDF lorsqu'ils sont en conflit et par la fusion desdits modèles RDF lorsqu'ils ne sont pas en conflit; et (e) à fournir un service permettant de rechercher les sujets ou les objets qui ont les mêmes prédicats sur la base du réseau RDF élaboré.
(KO) 본 발명은 구조적 형식을 갖추고 있지 않은 비구조적 문장들로 이루어진 텍스트 문서로부터 RDF 모델을 이루는 단위인 Subject, Predicate, Object를 추출하여, 각 개체들 간에 의미적으로 동일 개체인지 여부에 따라 개체를 식별하여 RDF 네트워크를 이루고, RDF 네트워크에 근거해 동일한 관계명(Predicate)을 가지는 주체(Subject) 또는 객체(Object)들을 검색하여 관련 정보로 제공할 수 있도록 된, RDF 네트워크 기반 연관검색 서비스 시스템 및 방법에 관한 것이다. 본 발명에 따른 RDF 네트워크 기반 연관검색 서비스 방법은, (a) 구조적 형식을 갖추지 않은 비구조적 문장들로 이루어진 텍스트 문서로부터 주체(Subject), 관계명(Predicate), 객체(Object)를 추출하는 단계; (b) 추출된 하나의 상기 주체와 하나의 상기 관계명 및 하나의 상기 객체로 이루어지는 RDF 모델을 생성하는 단계; (c) 상기 RDF 모델들을 비교하여 의미적으로 충돌하는지를 판단하는 단계; (d) 상기 RDF 모델 간에 충돌하는 경우 분리하고, 충돌하지 않는 경우에 병합하여 RDF 네트워크를 조성하는 단계; 및 (e) 상기 조성된 RDF 네트워크에 근거해 상기 관계명이 동일한 상기 주체들 또는 상기 객체들을 검색하는 서비스를 제공하는 단계를 포함한다.
