OntoLex 2002
Ontologies and Lexical Knowledge Bases

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:

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.

Two European thematic networks will support the workshop: ELSNET and OntoWeb.
