Semantic Web

The idea of hyperlinks has driven the Internet for a very long time now. Hyperlinks have actually done a wonderful job in bringing together information from all realms of life and integrating it in one place, the World Wide Web as we call it. However, what we see with the web today is structured text with multimedia objects such as images and interactive forms- what we can call information, but unstructured information.

The reason I am talking about all this web, structured information, and hyperlinks here today is because of the last few classes spent by my Professor disussing Semantic Web. Now, as my Prof puts it, today's web is primarily documenting almost everything that is available. What it is not capable of doing is the automation of data and information processing. So, in other words, with the World Wide Web today, people really know what the hyperlink means, but a machine cannot understand what the link means and how is it actually "linked" to the other document.

Semantic Web today is being seen as a solution to this as it would add logic to the Web, use rules to make inferences, decide actions and answer questions by providing a framework that allows data sharing and reuse across application, enterprise, and communities. As the founder of the Web, Berners-Lee, puts it, "The 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 cooperation."

But after what I have been hearing about all this metadata, ontologies,and stuff from him, at first go, I am not overly taken by this idea. The reason I say this is beacuse I think that the true context of the information can never be captured with the data and we are actually dependent on forms of human intervention for derivation of meaning and context! Now as I say this, I also realize that with my really restricted knowledge about all those research groups and their work on realizing a Semantic Web, these first impressions may really not be the correct ones!

i m not a tech person but have read the recent buzz about web 2.Is sementic web n web 2 the same or wat the difference ?

in terms of pure theory or idealism, the koncept of addin meta to data to derive meaning frm it runs into the endless loop of adding meta for the meta for the data. the real meta is already present in the data in the form of patterns n that is what should be extrakted

Startups for a stronger Resume?

When the whole web is abuzz with keywords such as Ajax, Web 2.0, Meebo and all, there is some uncertainity about how this new Internet Bubble will shape up.

Mike at Techdirt writes that some of these new startups may be only to actually stand out for the crowd and act as a strong resume.

While the complaint is that so many of these companies are built to flip rather than to be sustainable businesses, some are noticing that this process is really just a better way for some to stand out and get a job. You build a company quickly and cheaply that gets some attention, and a bigger company comes along to scoop up your company, giving you a nice "signing bonus." In effect, the purpose of these companies is to act as a strong resume to stand out from the crowd.

I'll have to admit that the nature of Pottermania is beyond my comprehension capabilities! As more and more fans of all ages and countries immerse themselves in Harry’s adventures, adding fuel to the belief that Pottermania is inescapable, I am purely and simply baffled by its ability to appeal to all ages.

Bored by the inactivity prevailing in this muggle world, I began to read the first one of the series and immediately concluded that reading beyond the tenth leaf was something impossible. Undeterred, I watched the first movie. I Hated it. But with the evil-wizard becoming apple of more and more eyes with every passing moment, around the world, it could only have been something wrong with me and so I watched the second movie. And then it became so easy to establish that I loathed the Potter Kid!

Just a passing thought - "Would it be a bad idea for a Potter special appearance in Oliver Twist? The poor kid could do with some wizardry."

Gmail Chat Disabled

The fact that it happened does not surprise me but that it took so long for our network administrators to figure it out does.

And if you are wondering how do you disable Gmail's chat features on your network, you only need locking DNS lookups to, by returning
