In order to capture knowledge of complicated product model, the expressive language ALCNHR + K(D) is introduced. It cannot only be able to represent knowledge about concrete domain and constraints, but also rules in some sense of closed world semantic model hypothesis. Also the paper takes an extension to the traditional description logic (DL) reasoning(More)
In the context of the semantic web; product knowledge is represented as product ontologies in it's conceptual level. Product ontology construction, integration, and evolution greatly depend on the availability of well-defined semantics and powerful reasoning tools, as to facilitate machine understandability of web resources. In order to capture the semantic(More)
