Abstract
This paper describes an experimental system GREEN for summarizing Japanese texts. Analyzing several aspects of discourse phenomena is in general indispensable to make a summary of good quality because each linguistic phenomenon mutually affects in a complex manner. From this point of view, we have developed a system GREEN, which is capable of summarizing Japanese editorial newspaper articles. This system uses several surface linguistic characteristics appeared in Japanese texts. We evaluate the performance of the system using a method of questionnaire where human subjects evaluate the quality of the summaries generated by the system.
