Generating huge interest and backed by the global WorldWideWeb consortium the semantic web is the key initiative driving the future of the World Wide Web. Towards the Semantic Web focuses on the application of Semantic Web technology and ontologies in particular to electronically available information to improve the quality of knowledge management in large and distributed organizations. Ontologies are formal structures supporting knowledge sharing and reuse. They can be used to represent explicitly the semantics of structured and semi-structured information which enable sophisticated automatic support for acquiring, maintaining and accessing information. Covering the key technologies for the next generation of the WWW, this book is an excellent mixture of theory, tools and applications in an important area of WWW research.
