Dawei Song (Alumni) 
Senior Lecturer
My research interests include various theoretical and practical aspects of information retrieval (such as logical models, language models, high-dimensional indexing and dimensionality reduction, relevance feedback, query expansion), text mining, applied logic, and their applications in knowledge discovery and management.
In addition to text information retrieval, I have also been heavily involved in several projects/bids on multi-media retrieval.
