document: An infrastructure for searching , reusing and evolving distributed ontologies The vision of the Semantic Web can only be realized through proliferation of well-known ontologies describing different domains . To enable interoperability in the Semantic Web , it will be necessary to break these ontologies down into smaller , well-focused units that may be reused . Currently , three problems arise in that scenario . Firstly , it is difficult to locate ontologies to be reused , thus leading to many ontologies modeling the same thing . Secondly , current tools do not provide means for reusing existing ontologies while building new ontologies . Finally , ontologies are rarely static , but are being adapted to changing requirements . Hence , an infrastructure for management of ontology changes , taking into account dependencies between ontologies is needed . In this paper we present such an infrastructure addressing the aforementioned problems .
