Research Interests

     

Database, Data Mining, Text Mining, Information Retrieval   

My current research:

·         Mining forums (including Community Question Answering) and social network

o   Extracting Question Answer pairs from forums to enrich the knowledge base of CQA services (related papers: SIGIR08, ACL08 )

o   Routing questions to expert users (related paper: ICDE09)

o   The use of categorization information to improve question search (related paper: CIKM09, WWW2010)

o   Computing link-based similarity (related paper: ICDM09)

·         Integrating information retrieval and database systems 

o   Efficient processing of spatial keyword queries (related paper: VLDB09)

My past research interests include classifying gene expression data, mining frequent patterns, XML, etc.
