법은 실생활에 직접 영향을 미치는 중요한 정보원이다. 법률 정보가 전자적으로 접근할 수 있게 되었음에도 불구하고, 현행 키워드 기반 검색시스템은 법률용어와 일상용어의 불일치, 생략형의 용어 사용, 법률용어의 다의성, 법률 정보의 대량 생산 그리고 질의-응답 형식의 검색 욕구 등의 문제를 잘 해결하지 못하고 있는 실정이다. 이러한 문제를 해결하기 위한 하나의 방식으로 온톨로지 기반 검색시스템이 제시되고 있다. 본 연구자는 법률 온톨로지와 그 온톨로지를 기반으로 하는 법률 검색시스템(실험시스템)을 구축하는 연구와, 실험시스템의 평가를 위하여 현존하는 키워드 기반 법률 검색시스템(비교시스템)과 비교 실험을 통해 검색 성능과 이용자 만족도를 평가하는 연구를 수행하였다.
The law affects our daily lives, and hence, constitutes a crucial information resource. However, electronic access to legal information using keyword-based retrieval systems appears to provide users with limited satisfaction. There are many factors behind this inadequacy. First, the discrepancies between formal legal terms and their counterparts in common language are quite large. Second, the situation is further confounded by frequent abbreviations in legal terms. Third, even though there is a constant deluge of legal information, users’ needs have evolved to demand more Q and A type searches. All of these factors make the existing retrieval systems inefficient and ineffective. This article suggests an ontology-based system as a means to deal with such difficulties. To that end, a legal retrieval system(experimental system), built on the basis of a newly-constructed law ontology, was tested against a keyword-based legal retrieval system(existing one), yielding data on their relative effectiveness in retrieval and user satisfaction.
