Description/Abstract

We address the life cycle of semantic web based knowledge management from ontology modelling to instance generation and re-use. We illustrate through a semantic web based knowledge manage-ment approach the potential of applying semantic web technologies in Geodise, an e-Science pilot project in the domain of Engineering De-sign Search and Optimization (EDSO). In particular, we show how on-tologies and semantically enriched instances are acquired through knowledge acquisition and resource annotation. This is illustrated not only in Protégé with OWL plug-in but in a light weight function annota-tor customized for resource providers to semantically describe their own resources to be published. In term of the reuse, advice mechanisms in particular a knowledge advisor based on semantic matching are de-signed to consume the semantic information and facilitate service dis-covery, assembly and configuration in a real problem solving environ-ment. An implementation has demonstrated the integration of the advi-sor in a text mode domain script editor and a GUI mode workflow composition environment. Our research work shows the potential of using semantic web technology to manage and reuse knowledge in e-Science.
