Workshop Description

One of the crucial tasks to be performed towards the realization of the vision of the Semantic Web is the encoding of human knowledge in ontologies using formal representation languages. Simply creating an ontology is not enough though; ontologies, just like any structure holding knowledge, need to be updated for several reasons, including a change in the world being modeled, a change in users' needs, the acquisition of knowledge previously unknown, classified or otherwise unavailable or a design flaw in the original conceptualization. In all these cases, the representation of our knowledge in the ontology should be modified so as to form a more accurate or adequate conceptualization of the domain. Such a modification presents several difficulties from both the practical and the theoretical point of view, as it is not always clear what the expected, or desired, result of any particular modification should be, nor how such a result can be determined.

Workshop Objectives and Topics of Interest. This workshop aims to bring together researchers interested in the field of ontology dynamics in order to discuss and analyze important characteristics, open research issues and recent research developments on the field. We encourage submissions on all topics related to ontology dynamics, including theoretical work on the issues involved directly or indirectly with change as well as applications or implemented systems related to such issues. We are particularly (but not exclusively) interested in the following topics:

  • Ontology evolution
  • Ontology versioning
  • Formal aspects of ontology dynamics
  • Foundational issues
  • Extensions to ontology languages to better support change
  • Belief revision for ontologies and the Semantic Web
  • Inconsistency handling in evolving ontologies
  • Change propagation in ontologies and metadata
  • Ontologies for dynamic environments
  • Dynamic knowledge construction and exploitation
  • Case studies, software tools, use cases, applications
  • Open problems
