Report on SIGSEM, June 2004 Patrick Blackburn and Harry Bunt The period since the last SIGSEM report was written (January 2004) has been relatively quiet. Over the last five months SIGSEM has not organised any of its own events, but it has supported a meeting of its Working Group on the Representation of Multimodal Semantic Information and it has endorsed a number of other events . In particular, computational semantics will be heavily represented at ESSLLI 2004 which takes place in Nancy, France, from 9-20 August 2004 (see http://esslli2004.loria.fr/) and SIGSEM has endorsed 4 courses at this summer school, namely: Computational semantics (Introductory Course) Alexander Koller, Aljoscha Burchardt and Stephan Walter Reasoning with natural language (Introductory Course) Ian Pratt-Hartmann (University of Manchester) Recent developments in computational semantics (Advanced course) Markus Egg and Valia Kordoni Modelling information structure for computational discourse processing Ivana Kruijff-Korbayova Pre-registration figures indicate that all four courses will be well attended (indeed the course by Koller et al looks set to be the most popular course of the summer school). A special issue of the Journal of Logic, Language and Information, edited by Michael Kohlhase, devoted to inference in computational semantics has appeared (Journal of Logic Language and Information, Volume 13, No. 3, Spring 2004). This contains a selection of papers which were originally presented at ICoS-3, the Third International Workshop on Inference in Computational Semantics (a SIGSEM event). All papers were revised and re-refereed for the special issue. The ACL SIGSEM Working Group on the Representation of Multimodal Semantic Information held its third meeting in conjunction with LREC 2004 in Lisbon in the form of a joint meeting with the ISO (International Standards Organization) Technical Committee on Terminology and Language Resources. This meeting has resulted in the identification of a number of aspects of semantic annotation and representation for which small task groups have been formed that will report at the WG's next meeting. The next major activity in which SIGSEM will be involved will be IWCS-6, the Sixth International Workshop on Computational Semantics, 12 - 14 January 2005 in Tilburg, the Netherlands. For more information see the IWCS-6 website http://let.uvt.nl/research/TI/sigsem/iwcs/iwcs6 Immediately preceding IWCS-6, on 10-11 January 2005, the WG on the Representation of Multimodal Semantic Information will have its fourth meeting at Tilburg University. This meeting will be open to IWCS-6 participants. For more information see the Working Group's website at http://let.uvt.nl/research/TI/sigsem/wg
