SECOND AND FINAL CALL FOR PAPERS
In Association with
4th INTERNATIONAL CONFERENCE ON LANGUAGE RESOURCES AND EVALUATION
LREC2004 http://www.lrec-conf.org/lrec2004/index.php
Main conference 26-27-28 May 2004
The use of ontological knowledge in language technology applications goes a long way back. Recently, however, the project of turning the World Wide Web into a machine understandable resource to access digital information (the so-called Semantic Web) has stimulated a renewed interest in ontologies. In several recent workshops and conferences, researchers have investigated their nature and application potential for knowledge management, information retrieval and extraction, information exchange in agent-based systems as well as dialogue systems. Attention is being drawn to new aspects of ontology research such as ontology coordination and mapping aspects that are particularly relevant for distributed environments such as knowledge grids and the semantic web. In fact the annotation of web resources in agreement with concepts and relations as defined in ontologies, is useful for establishing a conceptual support for knowledge communication.
From this perspective, lexicographers, lexical semanticists and ontologists are joining forces to build innovative systems for integrating ontological knowledge with lexical and semantic resources. Important examples of this interaction are the recent works on the conceptual analysis of WordNet (one of the first lexical knowledge bases), and the wide use of upper ontologies in innovative international projects like EuroWordNet, SIMPLE, Balkanet, DWDSnet. WordNet was designed and built entirely by psychologists, linguists, and lexicographers. Nevertheless, there are obvious parallels with ontologies, especially in the kinds of structuring relations used (taxonomical links, meronymy or part-of, etc.), and indeed WordNet has for years attracted the attention of philosophers and ontologists. In this context, the distinction between conceptual (possibly axiomatic) ontologies and lexical ontologies (which contain both linguistic and ontological information) has become more and more central in the field.
In this workshop we want to discuss ontologies as resources per se, as well as for what concerns the relation between ontological knowledge and language. This relation can be investigated from a number of different angles, for example what differences and similarities there are between ontologies and more traditional lexical resources such as dictionaries and wordnets; how ontologies can be extracted from language corpora; what role language plays in the definition and mapping of ontologies; and finally, how ontologies can be used to treat language in language technology applications in particular applications for distributed environments.
Topics to be addressed in the workshop include, but are not limited to:
Two discussions will be organised around the following topics:
A new scientific community is growing around this largely interdisciplinary area: following the spirit of the previous two OntoLex workshops, this workshop aims at being an important meeting point for researchers involved in the fields of lexical resources and ontologies, favouring the exchange of scientific experiences and proposing new directions of inquiry. This year, the workshop particularly welcomes contributions from researchers that are investigating the application of ontologies and lexical resources in distributed environments such as knowledge grids and the semantic web.
Participants are invited to submit an extended abstract of max 3000 words related to one or more of the topics of interest. Papers can describe research results as well as work in progress. Each accepted paper will receive a slot of 30 minutes for presentation (20 minutes talk and 10 minutes for discussion). Demonstrations of ontology applications are encouraged as well (a demonstration outline of 2 pages can be submitted). Each submission should show: title; author(s); affiliation(s); and contact author's e-mail address, postal address, telephone and fax numbers. Submissions must be sent electronically in PDF to Alessandro Oltramari oltramari@loa-cnr.it.
As soon as possible, authors are encouraged to send a brief email indicating their intention to participate, including their contact information and the topic they intend to address in their submissions. Proceedings of the workshop will be printed by the LREC Local Organising Committee.
The workshop will consist of a morning session and an afternoon session, and include scientific paper presentations from workshop participants as well as general discussions.
For this full-day workshop, the registration fee is 100 EURO for LREC conference participants and 170 EURO for other participants. These fees will include a coffee break and the Proceedings of the Workshop.
