"Ontology Alignment Algorithms and their Application in K-WfGrid"

Pursuing the idea of 'invisible Grid' and hiding the complexities of Grid
environment from the user, the K-Wf Grid project aims at extensive use of
semantic informations gathered in various ontologies stored in the Grid
Organizational Memory in order to support semi-automatic construction of
workflows. Registering new Grid services involves integrating their semantic
descriptions with knowledge already existing in GOM. This task can be
accomplished with ontology similarity methods.

The talk will give overview of existing similarity measures and concentrates
on their applicability to the use case of analyzing
semantic descriptions of Grid services. Also, a prototypeontology alignment
tool developed in the K-Wf Grid project will be presented.
