[Corpora-List] CALL FOR PARTICIPATION: GEMS-2010 workshop at ACL, on distributional semantics

[Marco Pennacchiotti]

	***** CALL FOR PARTICIPATION *****

ACL 2010 Workshop
GEMS-2010 : GEometrical Models of Natural Language Semantics

July 16, 2010
Venue A, Room II
Uppsala University, Sweden

*****
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.
