Abstract (in Japanese) (See Japanese page) 
(in English) Time dependent documents (daily reports, papers/magazines, user generated web contents etc.) contain topics; some are sustained through several time-span and the others appear suddenly. We report a method to analyze both gradual transition of topics and upcoming topics. The time dependent clustering method weights not only keywords in existing clusters, but also timely keywords and encourages creating new clusters. Adopting the method to test data showed performance to visualize topic transition and discover new topics.
