-====== Lexical Semantics Workshop (ESSLLI 2008)  ====== +The page you are looking for has moved to [[http://wordspace.collocations.de/doku.php/workshop:esslli:start]].

-**Bridging the gap between semantic theory and computational simulations**\\ +
-//Workshop at [[http://www.illc.uva.nl/ESSLLI2008/|ESSLLI 2008]], Hamburg, August 4-9 2008// +
- +
- +
-===== 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 have been proposed as +
-plausible simulations of human semantic space organization, +
-careful and extensive empirical tests of such claims are still lacking. +
- +
-Systematic evaluations of these models 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 formal semantics, 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 single scholars +
-and research teams 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. Specifically, we envisage the +
-following tasks: +
- +
-  * categorization +
-  ** concrete nouns categorization +
-  ** concrete vs. abstract nouns discrimination +
-  ** verb categorization +
-  * modeling free association +
-  * generation of salient properties of concepts +
-  * one or more tasks to test semantic compositionality +
- +
-The focus is NOT on competition, but on understanding how different +
-models highlight different semantic aspects, how far we are from +
-an integrated model, and which aspects of semantics are beyond the +
-reach of purely distributional approaches.  +
-In fact, we believe that the current +
-state of the art on computational semantics  +
-does not need to discover the best model, but rather +
-to enlarge the understanding of the limits and potentialities  +
-of different approaches when confronted with cognitively realistic tasks.  +
-To this effect, annotated +
-datasets will be distributed to the participants, who are +
-encouraged to explore them and highlight interesting aspects of their +
-models' performance, conduct quantitative and qualitative error analysis, etc. +
- +
-In addition to these practical tasks, theoretical and experimental papers +
-discussing the relation between distributional and symbolic approaches to meaning +
-are also invited.  We are particularly interested in papers that analyze our +
-task data sets from a theoretical perspective or that discuss simulation results +
-and their implications for semantic and cognitive theory. +
- +
-Through collaborative preparatory work on the Word Space wiki  +
-([[http://wordspace.collocations.de/|wordspace.collocations.de]])  +
-and thanks to the ESSLLI +
-multiple-day workshop format, we hope that this initiative will foster +
-collaboration among the nascent community of researchers interested in +
-computational semantics from a theoretical rather than engineering-oriented +
-point of view. +
- +
-Ongoing work on data-set preparation can be monitored at [[http://wordspace.collocations.de/doku.php/data:start|http://wordspace.collocations.de/doku.php/data:start]] +
- +
-We ask for expressions of interest from researchers and teams that +
-are planning to take part in the initiative and might want to contribute to +
-the desing of the tasks and test sets. +
