Ontologies and Lexical Resources
in Distributed Environments

(soon available)

Centro Cultural de Belem
LISBON, Portugal
29th may 2004

In Association with
4th INTERNATIONAL CONFERENCE ON LANGUAGE RESOURCES AND EVALUATION
LREC2004
Main conference 26-27-28 May 2004

Motivations and aim

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
Grid and 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:

- Design principles and methodologies for upper-level ontologies and
semantic lexical resources

- Evaluation, comparison, mapping and integration of ontologies and
lexical resources

- Applications of ontologies and semantic lexical resources in LT
applications (e.g. QA, Information Retrieval, Information Extraction,
Machine Translation)

- Role of semantic lexical resources in ontology learning

- Methods to derive ontological knowledge from text

- Methods to annotate text with reference to an ontology

- Ontology-based query expansion techniques

- Ontologies and multi-lingual lexical resources

- Ontologies and ontology mapping in multi-lingual applications

- Ontologies and lexical resources for meaning negotiation

Two discussions will be organised around the following topics:

- Filling the gap between axiomatic and linguistic ontologies

- The role of lexical resources in the Semantic Web and the Knowledge
Grid

Reasons of interest

A new scientific community is growing around this largely
interdisciplinary area: following the spirit of the previous two
OntoLex workshops, both hosted by LREC, 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 Grid and Semantic Web.
Important dates

4th December 2003: Call for papers and demonstrations
30 January 2004: Deadline for paper submission
5 March 2004: Acceptance notifications and preliminary program
29 March 2004: Deadline final version of accepted papers
29 May 2004: Workshop

Submissions

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 .

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.

Time schedule and registration fee
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.
