"Therefore you thought about the automatic translation simple age to him?"
My research area is in the area of computational linguistics, or
natural language processing. In the past, I have focused on 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. This
analyzer may soon be released as a toolkit to the general public.
Until then, if you need to use this analyzer, please send me email. I
have 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In addition, I have done unpublished work in Amharic, Serbo-Croatian,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.
