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 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@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@seas.smu.edu) with the subject "SENSEVAL SUBMISSION". Submissions to the special session on prepositions should be emailed to Patrick Saint-Dizier (stdizier@irit.fr).

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.
