Abstract

<p>This paper describes a method for extracting opinions with a basis from assembly minutes of Japanese 47 prefectures. The authors released the web-based system for searching the assembly minutes of 47 prefectures. Users can overview speech records including a search keyword using the system. Furthermore, the system can show regional differences of speech record volume as a color-coded map. On the other hand, it is difficult for the system to extract speech records including opinions because of indetermination of search keywords. Such speech records including opinions are good materials for understanding political concept of assembly members. In this research, we examine a method for extracting sentences including opinions using predicate argument structures.</p>
