Semantic Web

What does Semantic mean?It stands for meaning.So is Semantic Web same as Web with meaning.Literally speaking quite so.Semantic Web is a web that is able to describe things in a way that computers can understand.

The Semantic Web was thought up by Tim Berners-Lee, inventor of the WWW, URIs, HTTP, and HTML.However, Semantic Web technologies are still very much in the infancy, and although the future of the project in general appears to be bright.

In simple terms, it is information being stored in a form that can be understood in a meaningful way.It makes use of RDF for describing resources and information on the web.RDF (Resource Description Framework) is a markup language for describing information and resources on the web.Putting information into RDF files, makes it possible for web spiders to search, discover, pick up, collect, analyze and process information from the web.

Resource Description Framework

RDF gives you a way to make statements that are machine-processable. Now the computer can't actually "understand" what you said, of course, but it can deal with it in a way that makes it seem like it does.

An RDF statement is a lot like a simple sentence, except that almost all the words are URIs. Each RDF statement has three parts: a subject, a predicate and an object.

N-Triples format is used for simple RDF statements. However, the official RDF specification defines an XML representation of RDF, which is a bit more complicated but says the same thing

Conclusion

Internet means different things to different people.Semantic Web as a technology promises more versatility and usability.Arguments rage over the usefulness of the technology, the difficulty of using RDF, and so on. However, its vision of a machine-readable web has numerous possibilities.Though some complain about its lack of definition, its envisages radical effect it will have on the Web.
