서술형 질의응답시스템의 부가의미역에 대하여 -법률분야 <조건>의 부가의미역을 중심으로-

This study focused on the need to consider the feature of documents for automatic language processing such as QA, and focuses on the need for detailed guidelines for semantic roles annotation. The purpose of this paper is to improve the performance of the QA system of descriptive legal documents. In the legal document, the analysis was focused on <conditions> among high-frequency semantic roles of adjuncts, and the necessity of a new semantic roles of adjuncts was discussed. Chapter 2, explained the importance of automatic recognition of semantic roles of adjuncts in the Q & A system. Chapter 3 introduced the semantic roles of Prop Bank and ETRI, and explained the necessity of classifyingsemantic roles of adjuncts for perception of boundary clauses. In order to annotate semantic roles of adjuncts for boundary clauses, it is necessary to examine high-frequency connective endings and analyze vocabularies which is distributed before and after the connective endings. In addition, it was analyzed whether a specific semantic roles of adjuncts can be recognized according to the distribution of the connective endings. In Chapter 4, a method of sequentially applying semantic roles of adjuncts when automatically finding answers to questions about the law was proposed. In a question about the law, <time> or <extent> can be interpreted as <condition> in an answer.
