SemEval-2007 (formerly Senseval) 4th International Workshop on Semantic Evaluations an ACL-SIGLEX event Call for Interest in Participation http://nlp.cs.swarthmore.edu/semeval Feedback requested by Dec. 1, 2006 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Senseval is the international organization devoted to the evaluation of Word Sense Disambiguation Systems. Senseval-1 took place in the summer of 1998 with tasks for English, French, and Italian, and culminating in a workshop held at Herstmonceux Castle, Sussex, England on September 2-4. Senseval-2 took place in the summer of 2001, and was followed by a workshop held in July 2001 in Toulouse, in conjunction with ACL-2001. It included tasks for 12 languages. Senseval-3 took place in the spring of 2004, and was followed by a workshop held in July 2004 in Barcelona, in conjunction with ACL-2004. More than 55 teams participated with over 160 systems in its 16 tasks. We are now getting ready for SemEval-2007! As the nature of the tasks in Senseval has evolved to include semantic analysis tasks outside of word sense disambiguation, the Senseval Committee is pleased to announce the debut of "SemEval-2007: 4th International Workshop on Semantic Evaluations". SemEval-2007 evaluation is scheduled to start February the 26th up to April the 1st, and the workshop is planned for June, hopefully in conjunction with ACL-07 in Prague. As with previous evaluations, participants will be provided with training data, and will have the chance to test their systems on common data sets. Similar tasks will use the same data format. 19 different tasks have been proposed for SemEval-2007. We are now seeking to get feedback from potential participants, and kindly ask those who may be interested to participate in one or more SemEval tasks, to fill in the call for interest in participation form available at: http://nlp.cs.swarthmore.edu/semeval Please fill in this form before December 1, 2006. Your feedback is very much appreciated and will help us better organize SemEval-2007! Thank you, SemEval organizers Eneko Agirre Lluís Màrquez Richard Wicentowski
