Abstract
In this paper the problem of managing ontological descriptions for a dynamically-changing Grid environment is addressed. The focus of the research is on unification of semantic descriptions for Grid services and resources through ontologies. The Grid Organizational Memory (GOM) has been designed and implemented to enable storing and accessing Grid metadata, kept in the form of ontologies. In GOM, ontology storage and management are designed to support the natural evolution process both in the knowledge structure and knowledge management services. An important element of the GOM framework is the ontology separation schema, specifying the internal vertical and horizontal dependencies according to the Virtual Organization thematic domains, efficiency of knowledge retrieval and ontology development support. The separation schema is applied in the knowledge base distribution model on the Grid. An ontology alignment-based approach is proposed to minimize user commitment on the Grid ontological metadata, to support ontology usage and development. In particular the ontology similarity based approach is presented as support for ontology updates, e.g. extension with new facts from external ontologies and environments, as well as a more efficient and complete, less implementation-bounded querying process. This paper presents research on semantic description of the Grid environment within the scope of the K-Wf Grid project that addresses knowledge-based semiautomatic workflow construction for applications on the Grid.
