Recently, the development of knowledge bases is considered to be a process of extending an ontology with specific knowledge of a particular application. Reuse of pre-existing knowledge sources gives rise to knowledge bases endowed with a common and standard terminology.

As representation formalism we use Description Logics (DL) that exhibit a reasonable tradeoff between expressive power and complexity of reasoning. Thus...

a water jet machining is an industrial tool capable of cutting a wide variety of materials using avery high-pressure jet of water, or a mixture of water and an abrasive substance. this paperaddresses the concept of the intelligent knowledge base system (ikbs) for optimization of productdesign and manufacturing process for water jet machining in computer based concurrentengineering environment. ...
