THE WORLD OF THE SEMANTIC WEB From Traditional Web to Semantic Web What is WWW? A first look at the semantic Web An introduction to metadata Search Engine in Both Traditional and Semantic Web Environments Search engine for the traditional Web Search engine for the semantic Web: a hypothetical example Further considerations The semantic Web: a summary What is the key to semantic Web implementation? THE NUTS AND BOLTS OF SEMANTIC WEB TECHNOLOGY The Building Block of the Semantic Web: RDF Overview: what is RDF? The basic elements of RDF RDF triples: knowledge that machines can use A closer look at RDF Fundamental rules of RDF Aggregation and distributed information More about RDF RDF tools RDFS, Taxonomy, and Ontology Overview: why we need RDFS RDFS + RDF: one more step toward machine readability Core elements of RDFS The concepts of ontology and taxonomy Another look at inferencing based on RDF schema Web Ontology Language: OWL Using OWL to define classes: localize global properties Using OWL to define class: set operators and enumeration Using OWL to define properties: a richer syntax for more reasoning power Using OWL to define properties: property characteristics Ontology matching and distributed information OWL ontology header Final camera ontology rewritten in OWL Three faces of OWL Validating Your OWL Ontology Related development tools Validate OWL ontology by using Web utilities Using programming APIs to understand OWL ontology THE SEMANTIC WEB: REAL-WORLD EXAMPLES AND APPLICATIONS Swoogle: A Search Engine for Semantic Web Documents What is Swoogle and what is it used for? A close look inside Swoogle Examples of using Swoogle FOAF: Friend of a Friend What FOAF is and what it does Basic FOAF vocabulary and examples Creating your FOAF document and getting into the circle Updating our camera ontology using FOAF vocabulary Mark Up Your Web Document, Please! Semantic markup: a connection between two worlds Marking up your document manually Marking up your document by using tools Semantic markup issues Semantic Web Search Engine Revisit: A Prototype System Why search engines again Why traditional search engines fail The design of the semantic Web search engine prototype Using the prototype system Why this prototype provides better performance A suggestion for possible implementation FROM THE SEMANTIC WEB TO SEMANTIC WEB SERVICES From Web Services to Semantic Web Services Web service and Web service standards From Web services to semantic Web services OWL-S: An Upper Ontology to Describe Web Services What is upper ontology? The concept of OWL-S OWL-S building blocks Validating your OWL-S documents Where is the semantics? Adding Semantics to Web Service Descriptions WSDL-S OWL-S to UDDI mapping Match-making engines A Search Engine for Semantic Web Services The need for such a search engine Design of the search engine Implementation details Usage example of the semantic Web service search engine Summary and Further Readings What have we learned?
