Professor Si's research spans a range of topics in information retrieval, machine learning, text mining, speech and multimedia processing, and data mining. His recent research focuses on federated search (distributed information retrieval), probabilistic models for information filtering, and text/data mining for life science.
Professor Si has designed systems with his colleagues and acquired good results in evaluation campaigns such as TREC (Text Retrieval Conference) and CLEF (cross-lingual evaluations forum). He has published more than 35 conference, journal and workshop papers.
