Motivations and aim

Originating in 2000 through a visionary initiative by Atanas Kiryakov and Kiril Simov, and hosted twice by LREC (2002 and 2004), OntoLex has recently turned into a yearly meeting (IJCNLP workshop in 2005) for a growing interdisciplinary community of lexicographers, ontologists and computational linguists.

In this 2006 edition we will have a special focus on the integration of ontologies and lexical resources for Semantic Web technologies. The challenging idea of building a Semantic Web, i.e. an extended web of machine-readable information and automated services where contents can be accessed and shared by both human and artificial agents is a growing and very active field of research. This new framework is deeply influencing also emergent research on the integration of computational ontologies and lexicons, since the mutual relations between these two different types of resources are key components for semantic specification and interoperability.

 

Topics of interests:

         Ontologies and multi-lingual lexical resources

 

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 ñ aspects that are particularly relevant for distributed environments such as Kknowledge Ggrids and Sthe 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 ñ 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 

 

oTwo 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

OntoLex 2006 aims at establishing itself as the central meeting point for researchers involved in building, integrating and exploiting lexical resources and ontologies. We are strongly convinced that adding an explicit semantic web ìdirectionî to this yearís edition will help to address multidisciplinary aspects and will stimulate new directions of inquiry.

Panel (1 hour) on Approaches for Semantic Interoperability:

In the domain of Language Resource Management two questions are frequently raised: (1) What is the most promising framework in which to represent knowledge about linguistic concepts? (2) Should one construct an instance of the framework ëtop-downí, based on theoretical concerns, or ëbottom-upí, based on practical applications? Opinions differ on both questions. Regarding (1), within the E-Meld project the GOLD ontology was developed to contain definitions of concepts and the complex relations they may have. The GOLD ontology also contains root level concepts taken from SUMO to create a logically complete representation. On the other hand the ISO TC37/SC4 committee is voting for a simpler model in so far as it restricts itself to proper concept definitions according to ISO 11179 and 12620. Only where relations are inherent part of the definition such as with broader generic concepts they will be included. Regarding (2), both GOLD and the ISO Data Category Registry primarily follow a top-down design in so far that they claim to formalize ìwidely agreed community knowledgeî. On the other hand it is obvious that we are dealing with a highly dynamic research area and large differences in languages and theory, i.e., despite of the huge amount of legacy material which is out there not fitting to any predefined concept scheme, there is a continuous bottom-up process of (re-)defining concepts that address the immediate needs of the researchers involved. Four panelists will discuss the pros and cons of the different approaches, focusing on their relevance for the research process and for achieving interoperability.

Afterwards the floor will be open for discussion. The goal of the panel is to obtain a deeper understanding of the different approaches and to help in setting priorities.

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 the application of ontologies and lexical resources in distributed environments such as Kknowledge Ggrids and the Ssemantic Wweb.
