- W855861036 abstract "복수의 화제가 혼합되어 있는 문서에서 각 화제의 경계부분을 구분하여 결정하는 기술을 단락분할이라 한다. 이 기술은 정보검색의 분야에만 한정되지 않고 다양한 분야에서 중요한 역할을 담당할 기술이다. 잘 정의된 분야체계에 따라 구축된 분야연상어를 이용하여 단락분할을 시도한다. 분야연상어란 특정한 분야를 정확하게 연상할 수 있는 단어로서 잘 분류된 문서 컬렉션에서 구축할 수 있다. 이 분야연상어를 이용하여 문서를 관련된 분야별로 추출하여 의미기반 단락추출 방법을 제안한다. 화제의 계속성에 주목하여 분야연상어의 수준(범위)이나 연속출현성에 의해 계산된 계속도에 의해 화제의 실마리를 추적하고, 화제의 전환성을 고려한 방법을 제안한다. 문서 내 각 화제의 단락구분을 명확히 하여, 단락을 화제분야별로 추출하는 방법을 제안한다. 일본어 50문서를 실험한 결과 82%의 정확율과 63%의 재현율을 얻어 실용성을 기대할 수 있었고, 한국어에 적용하여도 좋을 것으로 예상한다. We propose a technique to extract a relevant passage from text collection based on field-associated terms since they tries to concentrate relevant text to users query. Documents are supposed to be managed as a whole without any segmentation into small pieces, but the method presented is independent upon any text-embedded auxiliary information, and is based on topic continuity and transition. For users needs-relative sentences or passages, we present a passage retrieval techniques by using occurrence frequency of a field-associated term to delimit text, that is likely to be relevant to a particular topic, considering continuity and transition within topic flowing in text. We evaluate 50 Japanese documents and verify the usefulness with 82% for average precision and 63% for recall." @default.
