국문 초록 (Abstract)

코퍼스 기반의 제 방법. 담화구조의 수사역할, 유사문장의 통합을 이용하여 발췌문과 기초적 요약문을 자동으로 작성하는 방법론을 구축하였다. 코퍼스에 따른 기법들의 효율적 한계치를 사전에 확인하였고 발췌/요약문의 신축적 작성을 위해서 요약문을 이루는 문장들의 수사역할을 목적, 배경, 방법, 결과. 결론 등으로 정하고 각각의 발췌기를 적용하였다. 발췌 성공률은 $90\%$이었다. 수사역할별로 선정된 문장의 합성과 분리를 위하여 유사도 공식을 이용한 유사문장의 통합, 불필요한 의미의 수식절, 삽입절의 제거, 짧은 문장들과 연결이 가능한 문장들의 합성을 시도하였다. 높은 발췌 성공률을 바탕으로 문장의 수사역할, 절의 용언어미 표징, 단서적 어구와 소재를 가미한 문장 정리 시스템의 개발이 요망된다.

다국어 초록 (Multilingual Abstract)

Various corpus-based approaches, rhetorical roles of discourse structure, and unifications of similar sentences were applied to construct the automatic Ext/Sums(extracts and summaries). Rhetorical roles of sentences like objective, method, background, result, conclusion, etc. for making elastic Ext/Sums were established and extraction engines according to respective role were prepared. The $90\%$ of Success rate in extracting the important sentences of sample articles was accomplished. Rearranging the selected sentences, it used unification of similar sentences using the cosine coefficient equation, deletion of unnecessary modification and insertion clauses, junction of short sentences, and connection of sentences able to link. They suggest the methods applying rhetorical roles of sentences, meaning and signature of noun and verb in clauses, and cue words and location will be researched to construct the more effective Ext/Sums.
