| Abstract(in English) | This paper studies issues regarding topic modeling of information flow in multilingual news and blog streams. If someone wants to find differences in the topics of Japanese and Chinese news / blog, it is usually necessary for him/her to carefully watch every article in Japanese and Chinese news streams at every moment. In such a situation, topic models such as LDA (Latent Dirichlet Allocation) and DTM (dynamic topic model) are quite effective in estimating distribution of topics over a document collection such as articles in a news / blog stream. Based on the results of estimating distribution of topics in Japanese / Chinese news streams, this paper proposes how to analyze cross-lingual alignment of topics in time series Japanese / Chinese news streams. This paper also proposes how to analyze differences of concerns and opinions among various Chinese news sites as well as blog hosts. |
