This paper describes a new environment, COE, for capturing and formally representing expert knowledge for use in the Semantic Web. COE exploits the ease of use and rapid knowledge construction capabilities of the CmapTools concept mapping system and extends them to support the import and export of formal, machine-interpretable knowledge representations, such as OWL, across multiple ontologies. Pragati’s Expozé tool suite complements COE’s ontology construction, browsing and navigation features by providing cluster-based search capabilities that expose existing reusable concepts relevant to the user’s focus of attention. Categories and Subject Descriptors I.2.4 Knowledge Representation Formalisms and Methods – representation languages, semantic networks. General Terms: Human Factors
