Abstract

본 발명은 키워드망을 이용한 문서순위 결정방법에 관한 것으로서, 종래기술에서의 종래 정보 검색 시스템은 대부분 메뉴 구동방식에 의해 단순한 키워드나 불리한 연산자를 입력하여 자료를 찾는 것으로 문장의 구조나 의미보다는 문서내의 단어 형태만으로 정보 검색을 함으로써 키워드를 정확하게 입력해야 했다.The present invention relates to a document ranking method using a keyword network. In the prior art, a conventional information retrieval system searches for data by inputting a simple keyword or an adverse operator by a menu driving method. By searching the information only in the form of words, the keywords had to be entered correctly.

또한 단어자체가 가지는 의미 모호성을 간과하였다.He also overlooked the ambiguity of the meaning of words themselves.

따라서, 유사한 의미의 다른 키워드는 찾을 수 없고 비정형화된 데이터에 대한 검색이 어렵고 사용자가 원하는 문서를 정확하게 찾아주지 못하는 문제점이 있었다.Therefore, there is a problem that other keywords with similar meanings cannot be found, search for unstructured data is difficult, and the user cannot accurately find a desired document.

이러한 문제점을 해결한 본 발명은 원래의 질의어를 이용하여 검색 되어진 문서들을 키워드망을 이용한 확장 질의어(Expanded query)로 다시 문서순위를 조정하여 정확률을 증가시킬 수가 있는 것이다.The present invention that solves this problem is to increase the accuracy rate by adjusting the document rank back to the expanded query (Expanded query) using the keyword query using the original query.

Description

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도는 본 발명에 따른 키워드망을 이용한 문서 순위 결정과정을 나타낸 흐름도,2 is a flowchart showing a document ranking process using a keyword network according to the present invention;

제3도는 원래의 질의텀중에서 의미 모호성을 가니는 텀이 있다면 의미 모호성을 해소한 후 확장질의를 구하는 과정을 나타낸 흐름도.FIG. 3 is a flowchart illustrating a process of obtaining an extended query after resolving semantic ambiguity if a term having semantic ambiguity exists among original query terms.

Claims (2)

입력된 자연어 질의어를 분석하여 동음이의어가 있을 경우 어의 모호성을 해소한 질의어 텀 추출과정과 질의어 확장과정으로 이루어진 것을 특징으로 하는 키워드망을 이용한 문서순위 결정방법.A method for determining document ranking using a keyword network comprising a query term extraction process and a query extension process, which resolves the ambiguity of a word when there is a homonym. 제1항에 있어서, 상기 확장된 질의어로 검색되어진 문서의 유사도를 계산함으로써 정보검색의 정확률을 증가시키는 것을 특지응로 하는 키워드망을 이용한 문서순위 결정방법.The method of claim 1, wherein the keyword network is adapted to increase the accuracy of the information retrieval by calculating the similarity of the documents retrieved by the extended query word. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
