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:
geographic information retrieval
Automatic Image Annotation
