David Yarowsky
David Yarowsky studies lexical ambiguity and language processing, including statistical methods and multilingual text analysis. Yarowsky earned a Harvard computer science degree in 1987, a Pennsylvania master’s in 1993 and a Pennsylvania doctorate in 1996. His research on word senses began during this training period. He later joined Johns Hopkins. With Grace Ngai, Yarowsky published work on inducing multilingual part-of-speech taggers and noun phrase bracketers through projection across aligned corpora. A separate shared paper with Ngai and Richard Wicentowski concerned multilingual text analysis tools.

1992–1995
Learning word senses from corpora
With William Gale and Kenneth Church, Yarowsky published shared work in 1992 on disambiguating word senses in large corpora. He published work on decision lists for lexical ambiguity in 1994 and unsupervised word sense disambiguation in 1995.

1999–2000
Language resources and evaluation
He coedited a 1999 volume on natural language processing using very large corpora with Susan Armstrong, Church, Pierre Isabelle and Evelyne Tzoukermann. With Philip Resnik, he published new evaluation methods for word sense disambiguation in 2000.

Tools across languages
With Grace Ngai, Yarowsky published work on inducing multilingual part-of-speech taggers and noun phrase bracketers through projection across aligned corpora. A separate shared paper with Ngai and Richard Wicentowski concerned multilingual text analysis tools.
