Abstract
Topical search engine is an extension of general-purpose search engines, which has become an important research subject in Web information retrieval recently. Focusing on the development of Web 2.0 applications, a result ranking approach is proposed on the basis of LDA model to rank the search results from Web forums. Compared with traditional methods, this approach takes up less storage space, and can more quickly and accurately respond to user inquiries. This work has important significance for the research of improving the performance of retrieval results of web forums.
