Overcoming the Barriers Advantages & Disadvantages Applications Definition : 3 Definition What is Semantic? An evolving development of the World Wide Web in which the meaning (semantics) of information and services on the web is defined, making it possible for the web to "understand" and satisfy the requests of people and machines to use the web content. Introduction : 4 Introduction Sir Tim Berners-Lee's vision. Components of Semantic Web. Resource Description Framework (RDF). RDF Schema Web Ontology Language (OWL). Purpose Evolution of Web : 5 Evolution of Web The Intelligence is in the Connections : 6 The Intelligence is in the Connections Connections between people Connections between Information Email Social Networking Groupware Javascript Weblogs Databases File Systems HTTP Keyword Search USENET Wikis Websites Directory Portals 2010 - 2020 Web 1.0 2000 - 2010 1990 - 2000 PC Era 1980 - 1990 PC’s 2020 - 2030 XML RDF SPARQL AJAX FTP SOAP File Servers Social Media Sharing Web 3.0 Web 4.0 Semantic Search Semantic Databases Distributed Search Intelligent personal agents Java Web 2.0 Flash OWL HTML SQL The Web The PC Windows MacOS SWRL Semantic Web Intelligent Web The Internet Social Web Web OS Limitations of HTML : 7 Limitations of HTML Structure of HTML webpage. Metadata tags, for example <meta name="keywords" content="computing, computer studies, computer"> <meta name="description" content="Cheap widgets for sale"> <meta name="author" content="John Doe"> provide a method by which computers can categorize the content of web pages.

Social Web Semantic Web Solutions : 10 Semantic Web Solutions The Semantic Web involves publishing in languages specifically designed for data: Resource Description Framework (RDF), Web Ontology Language (OWL), and Extensible Markup Language (XML). HTML describes documents and the links between them. RDF, OWL, and XML, by contrast, can describe arbitrary things such as people, meetings, or airplane parts. Giant Global Graph. Semantic Web Solutions : 11 Semantic Web Solutions These technologies are combined in order to provide descriptions that supplement or replace the content of Web documents. Thus, content may manifest itself as descriptive data stored in Web-accessible databases, or as markup within documents. Example- User wants to buy a mobile handset online.
