An Introduction of Semantic Web

The current WWW has a huge amount of data that is often unstructured and usually only human understandable. The Semantic Web aims to address this problem by providing machine interpretable semantics to provide greater machine support for the user. Semantic Web is an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in co-operation. The semantic web will provide intelligent access to heterogeneous, distributed information enabling software products to mediate between user needs and the information source available. Figure 1: Semantic Web Structure The Internet contains more than 10 billion static pages of information to be used by more than 1000 million users spread over the world. It is difficult to access & maintain this enormous amount of data using natural languages. It is rather difficult to bridge the gap between the available information and the techniques used for accessing it. The web content is increasing at very faster rate and difficult for search engines to cope up with it despite new techniques of searching. The Semantic Web’s establishes machine understandable Web resources. Researchers in this area plan to accomplish this by creating ontology and logic mechanisms and replacing HTML…
