******************************************************************************* FINAL CALL FOR PAPERS ACL 2010 Workshop GEMS-10 : GEometrical Models of Natural Language Semantics Second Edition Uppsala, Sweden; July 16, 2010 URL: http://art.uniroma2.it/gems010/ **** Submission Deadline: April 12, 2010 **** ******************************************************************************* NEW --> invited speaker : Katrin Erk, University of Texas at Austin NEW --> submission deadline extended : April 12, 2010 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). Semantic spaces based on simple contextual units have been early used in information retrieval. Later on, more linguistically principled spaces have been introduced for large-scale natural language learning problems, such as the acquisition of lexical taxonomies, word sense discrimination, pattern acquisition and conceptual clustering. More recently, specialized distributional models have been successfully applied to solve complex NLP tasks such as question answering, textual entailment and sentiment analysis. The goal of GEMS-2010, is to consolidate the experience of the first GEMS workshop, held at EACL in 2009. GEMS aims to stimulate research on semantic spaces and distributional methods for NLP, push for an interdisciplinary view, and amplify exchange of ideas, results and resources among often independent communities. In particular, 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. In this second edition, GEMS will broaden its focus to practical and industrial applications of distributional models. Many Web-companies such as Microsoft, Google and Yahoo! have in the last years embraced and effectively integrated in their infrastructure, semantic processors for computing distributional similarity among entities, queries, web pages and user-click-patterns. The workshop will aim at stimulating interactions between the academic and the corporate research sectors, and in discussing how far and in which way, distributional techniques are applied in Web Search. TOPICS OF INTEREST We invite submissions on any topic of current interest related to the application of semantic spaces to NLP and related disciplines, such as: - Unsupervised Learning through document-based, collocational and syntagmatic spaces - Supervised Learning and Word Spaces - From Unsupervised to Semi-supervised Learning in vector spaces - Eigenvector methods and Geometrical Embeddings - Higher order tensors and Quantum Logic extensions - Feature engineering in machine learning models - Computational complexity and evaluation issues - Graph-based models over semantic spaces - Logic and inference in semantic spaces - Psychological and cognitive theories of semantic space models - Applications in the humanities and social sciences - Large-scale implementations of distributional models (e.g. Map-Reduce) - Applications and impact on Web search, Web mining, Query log mining, etc. We also especially encourage submissions on the empirical evaluation of the above computational models within the following NLP tasks: - Word sense disambiguation and discrimination - Induction of Selectional preferences - Acquisition of lexicons and linguistic patterns - Conceptual clustering - Kernels methods for NLP - Modeling of linguistic theories and ontological knowledge - Manifold learning for NLP - Transfer learning for NLP - Quantitative extensions of Formal Concept Analysis SUBMISSION INSTRUCTIONS Authors are invited to submit papers on original, unpublished work in the topic area of this workshop. In addition to long papers presenting completed work, we also invite short papers and demos: - Long papers should present completed work and should not exceed 8 pages. - Short papers/demos can present work in progress or the description of a system, and should not exceed 5 pages. One more page is eventually allowed for bibliographic references only. As reviewing will be blind, please ensure that papers are anonymous. The papers should not include the authors' names and affiliations or any references to web sites, project names etc. revealing the authors' identity. Self-references that reveal the author's identity, e.g., "We previously showed (Smith, 1991) ...", should be avoided. Each submission will be reviewed by at least two members of the program committee. Accepted papers will be published in the workshop proceedings. Submission must conform to the official ACL style guidelines. For details, please refer to: http://www.acl2010.org/authors.html Submission will be electronic, via the Web-service at: http://art.uniroma2.it/gems010/submission.html Please consult the Workshop web page for more details.
