Research
My research area is in the area of computational linguistics, or natural language processing. I have focused my work in two major areas: computational morphology and semantic disambiguation. In particular, I have spent a lot of time looking at how these problems are the same/different across different languages.
For my doctoral thesis, I developed a multilingual, minimally supervised morphological analyzer. I demonstrated the effectiveness of this analyzer in Spanish, Portuguese, French, Catalan, Occitan, Italian, Romanian, Latin, English, German, Dutch, Danish, Norwegian, Swedish, Icelandic, Czech, Polish, Russian, Irish, Welsh, Greek, Hindi, Sanskrit, Estonian, Finnish, Turkish, Uzbek, Tamil, Basque, Tagalog, Swahili, and Klingon. In addition, I have done unpublished work in Amharic, Serbo-Croatian, Farsi, Arabic and Malay.
