Research Abstract

In this research, we propose a news analysis system that supports to compare articles from news sites in different countries. This system can support to analyze articles from multi facet (e. g., opinion, named entity). In this research, we propose to construct named entity database and opinion analysis system. In addition, we also propose a framework to evaluate such interactive system by using information that characterizes change of the users' knowledge about task domain.
