     "Word Sense Disambiguation: Recent Successes and Future Directions"

               A SIGLEX/SENSEVAL Workshop at ACL 2002 
                     University of Pennsylvania
                          July 11, 2002
      ================================================================



Description
-----------

The main purpose of the workshop is to discuss recent results in word
sense disambiguation (WSD), with reference to SENSEVAL-2.  The second
purpose is to begin planning SENSEVAL-3, the next evaluation exercise for
WSD systems.   

SENSEVAL-2, held 5-6 July 2001 in conjunction with ACL-01, unveiled the
results of over 90 systems submitted by 35 teams to tasks in 10 different
languages. At the time, it was not possible to do any in-depth analysis,
so it was agreed to organize a follow-up workshop in 2002 after sufficient
analysis could be done.    

The result is this one-day workshop dedicated to "Word Sense
Disambiguation: Recent Successes and Future Directions", with 17 regular
papers accepted for presentation. This includes 4 papers to be presented
in a special session on preposition semantics.    

The quality of the submissions was remarkably high.  The wide range of
problems addressed in these papers is encouraging, including in-depth
analyses of systems participating in SENSEVAL-2, improvements and new
approaches, comparative results, proposals for application-based
evaluations and for new tasks to be undertaken during SENSEVAL-3. The
workshop culminates in a session to start planning SENSEVAL-3. The central
question is: Can we, and should we, move towards a more-real application
scenario?  Panelists will present positions on the aim and scope of
SENSEVAL-3.        

We believe that this mixture of interesting approaches, results, and
discussion will provide a better insight into the recent successes in Word
Sense Disambiguation, and will help create a roadmap for future R&D  in
this field.
