Abstract (in Japanese) (See Japanese page) 
(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.
