Abstract:

Clustering of information unit entity based on the semantic similarity between the distribute information source is the important step of global view construction for information sharing in the virtual organization. This paper orienting the demands of constructing the global unified view of distribute information, using a metadata model based on ontology and the semantic similarity, defines the semantic clustering feature(SCF). And with the definition of SCF, this paper designs a SCF based hybrid hiberarchy clustering algorithm, and presents the analysis of the algorithm from theory and experiment.
