Semantic Web
Tim Berners Lee on the Semantic Web
Here is Tim Berners Lee explaining the vision of semantic web… let’s hear him & discuss what you understood.

RDF – Resource Description Framework
The Resource Description Framework (RDF), developed under the sponsorship of the World Wide Web Consortium (W3C), is an infrastructure that enables the encoding, exchange, and reuse of structured metadata.
This infrastructure enables metadata interoperability through the design of mechanisms that support common conventions of semantics, syntax, and structure. RDF does not specify semantics for each resource description community, but rather provides the ability for these communities to define metadata elements as needed. RDF uses XML (eXtensible Markup Language) as a common syntax for the exchange and processing of metadata. The XML syntax is a subset of the international text processing standard SGML (Standard Generalized Markup Language) specifically intended for use on the Web. Read the rest of this entry »
Need & Concept of Web 3.0 – The Semantic Web Basics
Short Intro: In this blog I am going to cover simplest intro to Semantic Web’s concept, It’s needs and the way we will be going to adopt it… So have a nice journey to this blog.
Why we need a new technology?
Data is present everywhere on web. That is generally hidden in HTML files and is often useful in some situations, 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. As an example, the information about weather forecast, local sports events, plane schedules, Major League Football statistics, and TV channel guides… all of this information is presented by numerous sites, but all in HTML. The problem with that is, in some contexts, it is difficult to use this data in the ways that one might want to have it in a form. So the Semantic Web can be seen as a huge engineering solution… but it is more than that. We will find that as it becomes easier to publish data in a re-purposable form, so more people will want to publish data, and there will be a incidental and effect. We may find that a large number of Semantic Web applications can be used for a variety of different tasks, increasing the modularity of applications on the Web.
The Concept:
The concept of Semantic Web was first thought up by Tim Berners-Lee, the inventor of WWW, URIs, HTTP. And now Semantic Web is under research phase all over the world. Read the rest of this entry »
