I came to
Research
My research is in the area of Cross-language
Information Retrieval. These are systems that allow a person to query in one
language (e.g. English) and retrieve relevant documents in other languages
(e.g. Spanish). In my thesis research I developed very effective approach to
cross-language retrieval based on translation via machine readable dictionary,
augmented with statistical techniques for reducing the effects of translation
ambiguity. The statistical techniques are based on analysis of word
co-occurrence in text.
Other Research
Interests
Much
of my research experience has been in information retrieval, but I have a
diverse research background. I have also worked with Paul Cohen on applying AI
techniques to exploratory data analysis and causal induction. In addition, I
spent a few years doing basic research in Molecular and Cellular Biology. My research interests span a broad spectrum
of information access and knowledge management issues. As the amount of on-line
information continues to explode, there is an increasing need for systems that
facilitate the manipulation and analysis of information. I am particularly
interested in developing techniques for text analysis and in exploring the ways
in which these techniques can be used for other data types. Areas of interest
include the following:

extraction
geographic
information retrieval
