Semantic Web

Introduction
The Semantic Web is the extension of the World Wide Web that enables people to share content beyond the boundaries of applications and websites. Most of all, the Semantic Web has inspired and engaged many people to create innovative semantic technologies and applications.

Semantic Web
The World Wide Web was invented by Sir Tim Berners-Lee in 1989. The key technology of the original web was the hyperlink. A user could click on a link and immediately go to the document identified in that link. Other semantic technologies include Natural Language Processing and Semantic Search.The difference between these technologies is that there is a completely different outlook on how storing, querying, and displaying information might be approached. Some applications, such as those that refer to a large amount of data from many different sources, benefit enormously from this feature. Others, such as the storage of high volumes of highly structured data, do not. There is a dedicated team of people at the World Wide Web consortium working to improve, extend and standardize the system, and many languages, tools and so on that have already been developed. However, Semantic Web technologies are still very much in their in-fancies, and although the future of the project in general appears to be bright, there seems to be little consensus about the likely direction and characteristics of the early Semantic Web.

Information that is generally hidden away in HTML files is often useful in some contexts, but not in others. The problem with the majority of data on the Web that is in this form at the moment is that it is difficult to use on a large scale, because there is no global system for publishing data in such a way as it can be easily processed by anyone. All data is presented by numerous sites in HTML. The problem with that is that, is some contexts, it is difficult to use this data in the ways that one might want to do so. So the Semantic Web can be seen as a huge solution. We will find that as it becomes easier to publish data in a simpler form, so more people will want to publish data. This will create a domino effect. We may find that a large number of Semantic Web applications can be used for a variety of different tasks, making applications on the Web more efficient.
