CALL FOR PAPERS **NEWS** FINAL CALL **NEWS** Distributional Lexical Semantics: Bridging the gap between semantic theory and computational simulations Workshop at ESSLLI 2008, Hamburg, August 4-9 2008 Workshop page: http://wordspace.collocations.de/doku.php/esslli:start ESSLLI 2008 page: http://www.illc.uva.nl/ESSLLI2008/ ** Background and motivation ** Corpus-based distributional models (such as LSA or HAL) have been claimed to capture interesting aspects of word meaning and provide an explanation for the rapid acquisition of semantic knowledge by human language learners. However, although these models have been proposed as plausible simulations of human semantic space organization, careful and extensive empirical tests of such claims are still lacking. Systematic evaluations typically focus on large-scale quantitative tasks, often more oriented towards engineering applications (see, e.g., the recent SEMEVAL evaluation campaign) than towards the challenges posed by linguistic theory, philosophy and cognitive science. This has resulted in a great divide between corpus-driven computational approaches to semantics on the one hand and theory-driven symbolic approaches on the other - a situation that is characteristic of the linguistic and of most of the cognitive tradition. Moreover, whereas human lexical semantic competence is obviously multi-faceted -- ranging from free association to taxonomic judgments to relational effects -- tests of distributional models tend to focus on a single aspect (most typically the detection of semantic similarity), and few if any models have been tuned to tackle different facets of semantics in an integrated manner. Our workshop purports to fill these gaps by inviting research teams and individual scholars to test their computational models on a variety of small but carefully designed tasks that aim to bring out linguistically and cognitively interesting aspects of semantics (see below for details). To this effect, annotated datasets are available on the workshop page: http://wordspace.collocations.de/doku.php/data:start. Participants are encouraged to explore them and highlight interesting aspects of their models' performance, conduct quantitative and qualitative error analysis, etc. ** Tasks and data sets ** Small annotated data sets are available on the workshop page. Participants are invited to apply their computational models and conduct a thorough analysis of the results. The goal is not to achieve better precision than competitors, but to understand the strengths and weaknesses of individual models, analyze and explain errors, etc. Theoretical discussions of the data sets from a linguistic or cognitive perspective are also invited and will complement the empirical findings. Ongoing work on data set preparation can be monitored at http://wordspace.collocations.de/doku.php/data:start. The workshop wiki is intended to provide a forum to discuss the organization of the tasks. We offer the following tasks: * categorization - concrete nouns categorization - abstract/concrete nouns discrimination - verb categorization * modelling free association - correlation with free association norms * generation of salient properties of concepts - comparison with speaker-generated features ** Important Dates ** - April 4, 2008: Paper submission deadline - April 24, 2008: Notification - August 4-9, 2008: Workshop in Hamburg (during the first week of ESSLLI) ** Paper submission instructions ** We welcome papers reporting results of experimenting with word space models on one or more workshop tasks, as well as comparing different models on the same task(s). Authors are asked to carry out their own evaluation, using if possible the tools provided on the website. We also welcome papers focussing on: * methodological and theoretical issues concerning word space models; * open challenges for distributional methods for semantic analysis; * interactions with formal approaches to meaning; * interactions with cognitive research on human semantic memory. The papers should not be longer than 8 pages, and they should be submitted anonymously in PDF format following the ACL2008 stylesheet. Submission must be sent to lexsem08@gmail.com, no later than April 4, specifying PAPER SUBMISSION in the subject and the authors' names and affiliation in the message body. ** Programme Committee ** Marco Baroni (University of Trento) (co-organizer) Reinhard Blutner (University of Amsterdam) Gemma Boleda (UPF, Barcelona) Peter Bosch (University of Osnabrueck) Paul Buitelaar (DFKI, Saarbruecken) John Bullinaria (University of Birmingham) Katrin Erk (UT, Austin) Stefan Evert (University of Osnabrueck) (co-organizer) Patrick Hanks (Masaryk University, Brno) Anna Korhonen (Cambridge University) Michiel van Lambalgen (University of Amsterdam) Alessandro Lenci (University of Pisa) (co-organizer) Claudia Maienborn (University of Tuebingen) Simonetta Montemagni (ILC-CNR, Pisa) Rainer Osswald (University of Hagen) Manfred Pinkal (University of Saarland) Massimo Poesio (University of Trento) Reinhard Rapp (University of Mainz) Magnus Sahlgren (SICS, Kista) Sabine Schulte im Walde (University of Stuttgart) Manfred Stede (University of Potsdam) Suzanne Stevenson (University of Toronto) Peter Turney (NRC Canada, Ottawa) Tim Van de Cruys (University of Groningen) Gabriella Vigliocco (University College, London) Chris Westbury (University of Alberta)
