The Semantic Web proposes the mark-up of content on the Web using formal ontologies that structure underlying data for the purpose of comprehensive and transportable machine understanding. ""Semantic Web Services: Theory, Tools and Applications"" brings contributions from researchers, scientists from both industry and academia, and representatives from different communities to study, understand, and explore the theory, tools, and applications of the Semantic Web. ""Semantic Web Services: Theory, Tools and Applications"" binds computing involving the Semantic Web, ontologies, knowledge management, Web services, and Web processes into one fully comprehensive resource, serving as the platform for exchange of both practical technologies and far reaching research.
