[David Yarowsky]

Keywords: Corpora, Self-Organization, Statistical Models, Unsupervised Learning


         THE THIRD WORKSHOP ON VERY LARGE CORPORA
         -----------------------------------------
  
                   Friday, 30 June 1995
                     8:45 AM - 5:25 PM
             MIT, Cambridge, Massachusetts, USA
                  at ACL-95 (June 26-29)

          (Sponsored by ACL's SIGDAT and SIGNLL)

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?
