With more substantial funding from research organizations and industry numerous large-scale applications and recently developed technologies the Semantic Web is quickly emerging as a well-recognized and important area of computer science. While Semantic Web technologies are still rapidly evolving Foundations of Semantic Web Technologies focuses on the established foundations in this area that have become relatively stable over time. It thoroughly covers basic introductions and intuitions technical details and formal foundations. The book concentrates on Semantic Web technologies standardized by the World Wide Web Consortium: RDF and SPARQL enable data exchange and querying RDFS and OWL provide expressive ontology modeling and RIF supports rule-based modeling. The text also describes methods for specifying querying and reasoning with ontological information. In addition it explores topics that are clearly beyond foundations such as tools applications and engineering aspects. Written by highly respected researchers with a deep understanding of the material this text centers on the formal specifications of the subject and supplies many pointers that are useful for employing Semantic Web technologies in practice. The book has an accompanying website with supplemental information. . Language: English
