Research on algorithm of Chinese BBS topic detection based on content analysis

Through analyzing and studying the BBS topic model, topic similarity, topic inspection, topic evaluation standards and topic developing trends, This paper designs and implements the Chinese BBS topic detection algorithm based on the content analysis, which includes obtaining BBS information by web crawler, processing BBS information based on the URL and Xpath page templates, realizing BBS information participle by ICTLAS, clustering BBS topic by Carrot2, analyzing hot topic based on the power spectrum and predicting of BBS topic based on time series. Finally, this paper developed the Chinese BBS Topic detection system used J2EE development kit, based on the eclipse integrated development environment, combined with Hibernate and GWT technology, and getting good results by tested in various BBS forums.
