International Semantic Web Conference

 

First International Workshop on Modular Ontologies

 

November 5, 2006
Athens, Georgia, USA


Workshop Description

 

Realizing the full potential of the Semantic web requires the large-scale adoption and use of ontology-based approaches to sharing of information and resources. Constructing large ontologies typically requires collaboration among multiple individuals or groups with expertise in specific areas, with each participant contributing only a part of the ontology. Therefore, instead of a single, centralized ontology, in most domains, there are multiple distributed ontologies covering parts of the domain. Because no single ontology can meet the needs of all users under every conceivable scenario, the ontology that meets the needs of a user or a group of users needs to be assembled from several independently developed ontology modules. Thus, in realistic applications, it is often desirable to logically integrate different ontologies, wholly or in part, into a single, reconciled ontology. Ideally, one would expect the individual ontologies to be developed as independently as possible from the rest, and the final reconciliation to be seamless and free from unexpected results. This would allow for the modular design of large ontologies and would facilitate knowledge reuse. Few ontology development tools, however, provide any support for integration, and there has been relatively little study of the problem at a fundamental level. In order for the full potential of the Semantic Web to be realized in practice, we need to come to terms with the characteristics of web ontologies. Specifically, next generation ontology languages and/or tools need to support collaborative construction, selective sharing and use of ontologies. In response to this need, there is a growing interest in, on the one hand, logical formalisms that support ontology modularization and the study of integration and segmentation problems on the other. Against this background, the proposed workshop aims to bring together researchers and practitioners to discuss the current state of the art and open research problems in ontology modularization and integration. A secondary goal of the workshop is to facilitate collaborations between different research groups.


Workshop Topics

 

  • Logical formalisms for modular ontologies: syntax, semantics, and expressivity
  • Sharing and reuse of ontology modules . linking and importing approaches
  • Collaboratively developing and sharing of ontologies and inter-ontology mappings
  • Identification and analysis of common scenarios for ontology integration or modularization
  • Methodologies for providing semantic guarantees on merged ontologies
  • Methodologies for extracting semantically meaningful modules from large ontologies
  • Selective information sharing between ontology modules
  • Features and limitations of DDLs, E-connections, and P-DLs
  • Requirements of modular ontology languages
  • Reconciling inconsistent ontology modules
  • Approaches to distributed reasoning and their soundness, completeness, efficiency
  • Extensions to ontology languages to support modularity
  • Modular ontology tools for collaborative ontology development
  • Case studies, software tools, use cases, and application
  • Open problems

Workshop Format

 

The workshop will consist of:
  • An opening session for introducing the workshop topics, goals, participants, and expected outcomes
  • A small number of invited talks carefully intermixed with presentation of contributed papers. The invited talks will give overviews of the main modular ontology language proposals, and of logical approaches to ontology modularization/integration.
  • Breaks between sessions, meant to encourage informal discussions related to the topics discussed in the sessions and to create opportunities for collaborations.
  • Discussion of open problems and future research directions
  • A wrap-up session summarizing the workshop (including formal or informal discussions).

Paper Submissions

 

We invite papers that report on completed or work in progress on relevant topic areas. All papers will be peer-reviewed by members of the WoMO-2006 program committee. The contributions should be prepared in PDF format according to the formatting guidelines for Springer-Verlag (LNCS). Submissions should be limited to a maximum of 6 pages for short papers, and 14 pages for full papers Submissions in PDF form should be made through the WoMO 2006 Submissions Site.


Extended versions of selected papers may be published in a special issue of a journal or an edited book.
