October 19, 20057 The Semantic Web is Comparable Not a different web, but an extension of the current one. It is essentially the addition of meaningful tags to content on the web, such that software can help us find things.

October 19, 200510 Weve heard all this before In 1995 the idea that the local restaurants, the muffler shop or the bed and breakfast would have their own web site was laughable. –They would need people to program HTML –They would need servers, admins, etc.
October 19, 200511 Semantic Web is already here only 642,000 documents with.rdf extension & 9,000.owl Yet 20,000,000 rdf triples are accessible (DARPA) 5,000,000 FoaFnauts Oracle 10.2 Every Adobe 6.0 + document
October 19, 200513 So, what is the Semantic Web? How do we know what anything is? –By analogy –By difference –By decomposition and description of the parts –By subsumption & categorization –By definition
October 19, 200514 Analogy A giant disk drive (internet) A query engine for the internet Surfing the web
October 19, 200515 By Difference Sometimes we understand things by what they are different from.

October 19, 200521 Decomposition and description of the parts Bicycle = frame + 2 wheels + gear train + brakes + seat + handle bars Semantic Web = shared ontologies + tagged content + inference engines + service composition
October 19, 200522 By subsumption and categorization A badger is a nocturnal [categorization] omnivore [prototypical] mammal [subsumption] The Semantic Web is a federated [prototypical] web [subsumption] with RDF tagged content [categorization]
October 19, 200523 By definition The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries. It is a collaborative effort led by W3C with participation from a large number of researchers and industrial partners. It is based on the Resource Description Framework (RDF), which integrates a variety of applications using XML for syntax and URIs for naming.RDF W3C The Semantic Web is a project that intends to create a universal medium for information exchange by giving meaning (semantics), in a manner understandable by machines, to the content of documents on the Web. Currently under the direction of its creator, Tim Berners-Lee of the World Wide Web Consortium, the Semantic Web extends the ability of the World Wide Web through the use of standards, markup languages and related processing tools.semanticsTim Berners-LeeWorld Wide Web ConsortiumWorld Wide Webmarkup languages Wikipedia
October 19, 200524 A closer look The power of the SW comes from a set of standards, each of which provides just a few capabilities. What follows is the essence of what is added at each level in the standards stack, starting with those we already know and love.
October 19, 200558 Re cap – Objective One: Theres much more to Semantics than good definitions
October 19, 200559 Objective Two – Did you learn a lot of exotic terminology? What is/are: –Semantics –Taxonomies and Ontologies –Inference –Description Logics –Classification and Reasoning –Semantic Web
October 19, 200560 Objective Three: to pursue further Send an email to me at firstname.lastname@example.org For either a glossary of semantic terms or the CIOs Guide to Semantics [I have a few bound copies] Visit our web site, many interesting free white papers www.semanticarts.com Semantic Wiki www.semanticwiki.com
