Ontologies and Lexical Knowledge Bases

3rd International Language Resources and Evaluation Conference, LREC2002

27th May 2002, Las Palmas, Canary Islands – Spain

Ontologies and Lexical Knowledge Bases

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: OntoWeb and ELSNET .

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

A discussion will be organized on the topic „Distinctions between lexical and ontological knowledge.“
