Research

I'm a researcher in information retrieval (IR) (e.g. web search engines). I'm particularly interested in evaluation of search engines, but also work in geographic search, cross language IR (CLIR), summarisation, image retrieval by captions, word sense ambiguity.

I have a number of active research projects and a number of research students
