My research interests are in natural language processing (NLP), information retrieval (IR) and the implementation of such techniques in real applications. The intelligent directory enquiry assistant (YPA) project is an example (going back quite a few years now ...) where the extraction of information from partially structured data together with engineering issues played major roles in making the YPA a usable online system.
I am developing techniques that allow the extraction of conceptual information from document collections and the utilization of such knowledge in retrieval tasks. The type of documents can range from Web pages to newspaper articles or other forms of vaguely/partially structured data. You can see these methods in action by trying out the University of Essex search engine (any feedback welcome!)We are also exploring how to implement and use such techniques in future intelligent home environments. This work is carried out as part of the research in the Digital Lifestyles Centre here at Essex.
