WebInsight

WebInsight: Towards Modeling Correlation and Evolution of Web Documents

Aims

The main aim of the WebInsight project is to explore topic and other content models for (cross-lingual) analysis, comparison and summarization of textual content. The research builds on and expands probabilistic models such as probabilistic Latent Semantic Analysis (pLSA) and Latent Dirichlet Allocation (LDA) and can be applied in many text mining tasks such as spatio-temporal text mining, cross-collection comparative analysis and cross-lingual mining. The research insights and the developed technologies are evaluated on Chinese and English Web documents.

Partner

Tsinghua University, China (Prof. Juanzi Li, Prof. Jie Tang and Prof. Maosung Sun).

Results

We have researched technology for cross-lingual information processing, more specifically we have shown that the cross-lingual Latent Dirichlet Allocation model can serve as a transfer learning method in cross-lingual clustering and categorization. The partners have organized a joint workshop, The 3rd Workshop on Social Web Search and Mining (SWSM2011): Analysis of User Generated Content Under Crisis in Beijing, China on July 28, 2011 during the 34th Annual International ACM SIGIR conference.

An edited book on mining of user generated content is in preparation.
