                           Call for participation

         "Word Sense Disambiguation: Recent Successes and Future Directions"

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


    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

    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.
