***** 2ND CALL FOR PARTICIPATION ***** EACL 2009 Workshop GEMS : GEometrical Models of Natural Language Semantics March 31, 2009 Athens, Greece Megaron Athens International Conference Center Room MC.3 URL : http://art.uniroma2.it/gems/ ***** Distributional models and semantic spaces represent a core topic in contemporary computational linguistics for their impact on advanced tasks and on other knowledge fields (such as social science and the humanities). The goal of the GEMS workshop is to further stimulate research on semantic spaces and distributional methods for NLP, by adopting an interdisciplinary approach to allow a proper exchange of ideas, results and resources among often independent communities. In particular, the workshop will provide a common ground for a fruitful discussion among experts of distributional approaches, collocational corpus analysis and machine learning; researchers interested in the use of statistical models in NLP applications (e.g. question answering, summarization and textual entailment) and in other fields of science; and experts in formal computational semantics. The workshop aims at gathering contemporary contributions to large scale problems in meaning representation, acquisition and use, based on distributional and vector space models. The workshop aims also to shed new light on the use of such techniques on complex linguistic tasks, such as linguistic knowledge acquisition, semantic role labeling, textual entailment recognition, question answering, document understanding/summarization and ontology learning. ***** REGISTRATION ***** Register at: http://www.eacl2009.gr/conference/registration ***** PROGRAM ***** 8:50 - 9:00 Welcome 9:00 - 9:50 Invited Talk: Patrick Pantel "Lexical Semantics in the Prime Time: Applications to Web Search" -- Session 1 -- 9:50 - 10:15 Marco Baroni and Alessandro Lenci One distributional memory, many semantic spaces 10:15 - 10:40 Yves Peirsman and Dirk Speelman Word Space Models of Lexical Variation 10:40 - 11:00 Coffe break -- Session 2 -- 11:00 - 11:25 Klaus Rothenhausler and Hinrich Schuetze Unsupervised Classification with Dependency Based Word Spaces 11:25 - 11:50 Lidan Zhang and Kwok-Ping Chan A Study of Convolution Tree Kernel with Local Alignment 11:50 - 12:15 Amaç Herdagdelen and Marco Baroni BagPack: A general framework to represent semantic relations 12:15 - 12:45 SHORT PRESENTATIONS : Fridolin Wild, Bernhard Hoisl and Gaston Burek Positioning for Conceptual Development using Latent Semantic Analysis Ruslan Mitkov, Le An Ha, Andrea Varga and Luz Rello Semantic similarity: which is the best method to compute it?
