Semantic Web Technologies: Trendz And Research In Ontology - Based Systems

0.0

Semantic Web Technologies provides a comprehensive overview of key semantic knowledge technologies and research. The authors explain (semi-)automatic ontology generation and metadata extraction in depth, along with ontology management and mediation. Further chapters examine how Semantic Web technology is being applied in knowledge management (“Semantic Information Access”) and in the next generation of Web services. Key Features A comprehensive overview of the state-of-the art in Semantic Web research and key technologies. Examines how Semantic web technology is being applied in knowledge management ("Semantic Information Access") and in the next generation of web services. Addresses the issues of (semi-) automatic ontology generation and metadata extraction. Discusses ontology management and evolution, covering language-independent ontology evolution, ontology change request specification, and ontology dependency. Including contributions by the top authorities in the field. Illustrates the theoretical concepts with three case studies on industrial applications in digital libraries, the legal sector and the telecommunication industry. About The Author Dr John Davies leads the Next Generation Web research group at BT. Current interests focus on the application of semantic web technology to knowledge management and semantic web services. John is industrial chair of the Semantic Web Services Initiative, co-organiser of the European Semantic Web Conference series and Project Director of the SEKT EU integrated project (Semantically-Enabled Knowledge Technologies). He has written and edited many papers and books in related areas. Rudi Studer is Professor at Institute of Applied Informatics and Formal Description Methods, University of Karlsruhe. His research spans the fields of business intelligence, e-learning, knowledge discovery and management, ontology-based knowledge management systems and the semantic web. He has authored numerous journal and conference papers on these topics. Paul Warren works in BT's Next Generation Web research group, where he is SEKT project manager and also responsible for the project's exploitation strategy. Paul has published widely on technology management, technology foresight, and recently the application of the Semantic Web. Table Of Contents Introduction. Semantic Web Technologies.
