Abstract

Recently, an environment in which public opinions are expressed about various areas is expanded around SNSs or internet potals, thus, opinion documents get bigger rapidly. Under these circumstances, it is essential to utilize automatic summarization techniques for understanding whole contents of large opinion documents. However, it is hard to summarize efficiently those documents with traditional text summarization technologies since the documents include subject expressions as well as features of targets objects. Proposed method in this paper defines features of opinion documents, and designed to retrieve representative sentences expressing opinions of those features. In addition, through experiments, we prove the usefulness of proposed method.

최근 SNS나 포털을 중심으로 다양한 분야 대해 대중들의 의견이 표현될 수 있는 환경이 확대되고 있고, 이로 인해 오피니언 문서들은 빠르게 대량화 되고 있다. 이러한 환경에서 대용량의 오피니언 문서들의 내용을 파악하기 위해서는 자동 요약 기술의 적용이 필수적이다. 하지만 오피니언 문서 내에는 대상 객체가 갖는 특성들과 주관적 표현들이 내재되어 있어 일반적인 요약 기법으로는 효율적인 요약이 불가능하다. 본 논문에서는 대용량의 오피니언 문서를 대상으로 주요 문장들을 추출하여 요약하는 기법을 제안한다. 제안된 기법에서는 사전에 정의된 오피니언 문서의 특성들에 대해서, 특성들에 대한 오피니언이 표현된 대표적인 문장들이 추출되도록 설계되었다. 또한 실험을 통하여 제안된 방법의 유용성을 증명하였다.
