Online Classification for news stream based on topic model
Masato Shirai, Takao Miura (Hosei Univ.) DE2014-22
Abstract (in Japanese) (See Japanese page) 
(in English) In this investigation, we propose online classification method of news stream using online topic model. In news stream, feature of class changes dynamically.
It is necessary to change the classification criterion adaptively. In addition, stream data, such as news articles, occurrence frequency of theme are influenced by burst of themes. To classify news stream, we consider both stationary distribution and transit distribution in each class.
