		 DEADLINE EXTENSION - CALL FOR PAPERS

  Word Sense Disambiguation: Recent Successes and Future Directions

                An ACL-SIGLEX/SENSEVAL workshop at ACL 2002
                      University of Pennsylvania
                            July 11, 2002


*****  The deadline for submissions has been EXTENDED  *****

*****  New submission deadline: April 11, 2002

*****  Please inform us asap if you think you'll submit a paper

*****  We are also accepting SHORTER PAPERS (1-3 pages long) that
       describe WSD systems for which improvements have been made
       since Senseval-2, or for which more detailed analysis of
       results has been made since Senseval-2, or which didn't
       participate in Senseval-2 but have been evaluated against
       Senseval data.

         Workshop:   http://www.seas.smu.edu/~rada/ACL02.WSD/
              ACL:   http://www.acl02.org/


DESCRIPTION

The main purpose of this workshop is to analyse and discuss the
results of SENSEVAL-2.  The second purpose is to start planning
SENSEVAL-3, the next evaluation exercise for word sense disambiguation
systems.

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

The format will be a mixture of refereed papers and panel sessions.

We now invite original submissions on any of the following topics:

 - Analysis of results of Senseval-2
 - Comparisons of results across different systems, techniques, and
   languages
 - Comparisons between SENSEVAL-1 and SENSEVAL-2
 - What makes some words easier to disambiguate than others
 - The efficacy of different corpora and sense inventories for WSD
 - Evaluation techniques and methodology, especially domain-, task-,
   and application-specific evaluation
 - Variation in the required sense inventories for different
   applications

The workshop will culminate in a session to continue planning
Senseval-3.  A central question is: Can we, and should we, move
towards a more-real application scenario?


SPECIAL SESSION ON PREPOSITION SEMANTICS

Prepositions have an extremely complex behavior: most are highly
polysemous, subject to numerous metaphorical transpositions, and enter
into a number of idiomatic or semi-idiomatic constructs. Semantically,
prepositions have a meaning which is in general abstract and largely
underspecified. Perhaps more than for any other syntactic category,
the exact meaning of a preposition is determined in context.

Within the WSD framework, we welcome papers that investigate polysemy,
metaphorical and metonymic uses of prepositions. Preposition
classification methods and semantic representation formalisms are also
of much interest.

This special session is organized by Patrick Saint-Dizier and
submissions should be emailed directly to him (stdizier at irit.fr) using
the guidelines below.  *** Papers should be submitted by 14 March. ***


SUBMISSIONS

Submissions should use the standard ACL style files (available at
http://www.cs.ualberta.ca/~lindek/acl02/style/).  Papers should not
exceed eight (8) pages, including references.

Please email your submissions to Rada Mihalcea (rada at seas.smu.edu)
with the subject "SENSEVAL SUBMISSION". Submissions to the special
session on prepositions should be emailed to Patrick Saint-Dizier
(stdizier at irit.fr).

BACKGROUND

The purpose of SENSEVAL is to evaluate the strengths and weaknesses of
WSD programs with respect to different words, different varieties of
language, and different languages.

SENSEVAL is managed by the SENSEVAL committee which reports to
ACL-SIGLEX.

The first SENSEVAL took place in the summer of 1998 for English,
French, and Italian, culminating in a workshop held at Herstmonceux
Castle, Sussex, England on September 2-4.  The second evaluation
exercise occurred in 2001, culminating in SENSEVAL-2: The Second
International Workshop on Evaluating Word Sense Disambiguation
Systems.  Systems were evaluated on "translation", "all-words"," and
"lexical-sample" tasks in Dutch, Czech, Basque, Estonian, Italian,
Korean, Spanish, Swedish, Japanese, and English.  Over 90 systems were
scored.
