An Analysis System of Corporate Evaluation on Bulletin Board Sites

Abstract

This paper proposes a system that analyzes corporate evaluation on bulletin board sites. The system downloads threads from bulletin board sites selected by a user and extracts articles from the threads. The system extracts both threads corresponding to the user's interests and expressions which represent the contents of the threads. The system shows analysis results to the user with three viewpoints. The paper evaluates the effect of the system through the user's trial operation. The paper improves the system by getting rid of the problem shown by the operation and verifies experimentally the effect of the improvement.
