SIGLEX is the Special Interest Group on the Lexicon, providing an umbrella for research interests on lexical issues ranging from lexicography and the use of online dictionaries to computational lexical semantics. SIGLEX is also the umbrella organization for Senseval/Semeval - the evaluation exercise for systems for the semantic analysis of text. The following ACL members are currently serving as SIGLEX officers: President: Rada Mihalcea, University of North Texas Secretary: Ted Pedersen, University of Minnesota, Duluth Executive Board: Francesca Bertagna, Istituto di Linguistica Computazionale (ILC-CNR) Stefan Evert, Universitat Stuttgart Katrin Erk, Saarland University Jimmy Lin, University of Maryland Diana McCarthy, University of Sussex Claudia Soria, Istituto di Linguistica Computazionale (ILC-CNR) Board Member with Special Portfolio/Webmaster: Ken Litkowski, CL Research One of the main events for 2007 was the Semeval (former Senseval) exercise for the evaluation of systems for the semantic analysis of text. The evaluation took place in Spring 2007, and the workshop is scheduled to take place on June 23-24 2007, in conjunction with the ACL conference in Prague. The co-chairs are Richard Wicentowski (Swarthmore College), Lluis Marquez (Universitat Politecnica de Catalunya), and Eneko Agirre (University of Basque Country). This has been a highly successful event, with 18 different tasks (selected out of the 25 submitted), more than 100 participating teams, and more than 125 systems. This represents a significant increase compared to the 14 tasks and 55 teams participating in Senseval-3. More information about Semeval is available from the event webpage http://nlp.cs.swarthmore.edu/semeval/. During 2006-2007, SIGLEX has endorsed the following events: * SemEval-2007, 4th International Workshop on Semantic Evaluations, Evaluation period: February 26, 2007 to April 1, 2007, SemEval-2007 Workshop, co-located with ACL-2007, June 23-24, 2007, Prague * TextGraphs-2: Graph-based Methods for Natural Language Processing, HLT/NAACL 2007 Workshop, April 26, 2007, Rochester, New York * A Broader Perspective on Multiword Expressions, ACL 2007 Workshop, June 28, 2007, Prague, Czech Republic (Endorsed by the ACL Special Interest Group on the Lexicon, Submission due March 26, 2007) * 4th ACL-SIGSEM Workshop on Prepositions, ACL 2007 Workshop, June 28, 2007, Prague, Czech Republic (Sponsored by the ACL Special Interest Group on Semantics, Submission due March 26, 2007) * Acquisition and Management of Mulitlingual Lexicons, Workshop at RANLP-2007, September 30, 2007 (Endorsed by the ACL Special Interest Group on the Lexicon, Submission due June 15, 2007)
