 THE THIRD WORKSHOP ON VERY LARGE CORPORA
 -----------------------------------------
 Friday, 30 June 1995
 8:45 AM - 5:25 PM
 MIT, Cambridge, Massachusetts, USA
 at ACL-95
 (Sponsored by ACL's SIGDAT and SIGNLL, LEXIS-NEXIS)

The workshop will present original research in corpus-based and
statistical natural language processing. Topics will include
sense disambiguation, grammar induction, part-of-speech tagging,
information retrieval, language modeling, and machine translation.
This year's theme is:

 Supervised Training vs. Self-organizing Methods

Historically, annotated corpora have made a significant contribution
to tasks such as part-of-speech tagging and sense disambiguation.
But annotated corpora are expensive and generally unavailable for
languages other than English. Self-organizing methods offer the hope
that annotated corpora might not be necessary. Can we achieve comparable
performance using little or no tagged training data? What are the tradeoffs?

Organizers: Ken Church and David Yarowsky
