             Ontologies and Lexical Knowledge Bases
        27th May 2002, Las Palmas, Canary Islands - Spain


Workshop motivation and aims

The rise of the semantic web has greatly increased the interest
in ontologies, but also added new critical requirements for them,
such as wide coverage, interoperability and multi-linguality. In
the perspective of the semantic web, the link between ontologies
and natural language appears to be crucial. Indeed, there is a
high level of correspondence between ontologies and lexical
knowledge bases. They are subject to the same requirements, and
there is an ever increasing potential and need for cooperation
between the two fields.

Following the tradition of the first OntoLex workshop (OntoLex'00
Sozopol, Bulgaria 2000), this workshop will focus on the links
between ontologies and lexical knowledge bases, aiming at being a
meeting point for a number of communities that are currently not
sufficiently connected:

- lexical semanticists;
- lexicographers and terminologists;
- ontologists with computer science background;
- ontologists with philosophical background;

- ontology users active in various areas (knowledge management,
 information extraction, information retrieval, machine
 translation, conceptual modelling, eCommerce).

The needs for greater interconnectivity among the above research
areas have been widely recognized in the last years. Two good
examples of an interdisciplinary approach are the use of upper
ontologies in European projects as EuroWordNet and SIMPLE, and
some recent work on the conceptual analysis of WordNet's
top-level taxonomy presented at FOIS2001.

Lexical knowledge bases are considered an important kind of
language resources. Moreover, lexical knowledge bases and
ontologies are starting to play a crucial role in the creation
and usage of other language resources such as syntactic
tree-banks and lexicons.

The workshop will take place on the 27th of May 2002 at Las
Palmas, Canary Islands - Spain (preceding the 3rd International
Language Resources and Evaluation Conference, LREC2002). Two
European thematic networks will support the workshop: ELSNET and
OntoWeb.


Topics of interest

- design principles for upper-level ontologies and semantic
 lexical resources;
- ways for handling systematic polysemy and compound concepts;
- interoperability between semantic lexical resources and
 ontologies;
- applications of ontologies and semantic lexical resources in IR
 and IE;
- role of semantic lexical resources in ontology learning;
- evaluation, comparison, mapping, and integration of ontologies
 and semantic lexical resources

One discussion will be organized on the following topic:

- distinctions between lexical and ontological knowledge.
