Abstract
This paper introduces the method that analyzes the corporate evaluation in bulletin board sites. The method generates a thread analysis report from the threads included in the sites by using 4 extraction processes, which are article extraction, event extraction, thread extraction, and phenomena extraction. The report is composed of important threads and their relevant information. The analysts can easily check whether the threads are important or not by looking through the report. The paper discusses the functions and the specification in order to construct the practical system incorporating into the method.
