    ABSTRACT

    We have been studying news services provided in simplified Japanese and targeting foreign residents in Japan who have difficulty in understanding daily news in Japanese. We started a trial news web service in easy Japanese on the web site "NEWS WEB EASY" in April 2012. The service is intended to be a way for us to study the effectiveness and problems of such services in real settings. In this paper, we outline the easy Japanese for news. We explain the characteristics of the web services and elaborate on the rewrite assistant tools that were specially developed for different workers to rewrite news of the same quality. We analyze the easy Japanese news and report that the intended quality of easy Japanese was preserved across different workers.

    ABSTRACT

    We show how opinion mining technology can be used to get an overview of viewers' comments about TV programs. Until recently, viewers' opinions could only be analyzed by reading comments from viewers. Recently, however, a computational method has been used to analyze opinion from viewers' comments. An outline for such technology is presented with a detailed application for NHK TV programs. The remaining problems and possibilities for future work are also discussed.
