Abstract

The writings frame and various rules based on discourse structure and knowledge-based methods were applied to construct the automatic Ext/sums (extracts & summaries) system from the straight news in web. The frame contains the slot and facet represented by the role of paragraphs, sentences , and clauses in news and the rules determining the type of slot. Rearrangement like Unification, separation, and synthesis of the candidate sentences to summary, maintaining the coherence of meanings, was carried out by using the rules derived from similar degree measurement, syntactic information, discourse structure, and knowledge-based methods and the context plots defined with the syntactic/semantic signature of noun and verb and category of verb suffix. The critic sentence were tried to insert into summary.

웹의 보도기사에 관한 자동요약시스템을 구축하기 위하여 담화구조와 지식기반 기법을 적용한 글구조 프레임과 제 규칙들을 작성하였다. 프레임에는 문단과 문장 및 절의 역할, 문단과 문장의 성질, 역할을 구분하는 판별규칙, 주요문장 발췌규칙, 그리고 요약문 작성규칙 슬롯이 포함되었다. 문맥정의, 고유명사 등을 안내하는 'if-needed'와 변화된 슬롯 값을 알려주는 if-changed 패싯도 구비되었다. 슬롯이나 패싯의 실제 값들을 추출 표현하는 과정에서 문구의 수사적 역할과 단어 최상위 범주 및 줄거리 단위를 참조하였다. 의미흐름의 연결성을 유지하면서 요약 문장들을 통합, 분리, 합성하는 재구성은 유사도공식, 구문정보, 담화구조와 지식기반 방법에서 도출한 제 규칙 및 문맥정의를 이용하였고 비평과 같은 새로운 문장을 생성하였다.
