What is Semantic Web?
Today we here more about Semantic Web or Web 3.0. But most of my friends are not able to grab what is semantic web or what’s the specialty of web 3. Semantics is the study of meaning. So Semantic Web means a Web with meaning, got confused? Don’t worry I’ll explain.
In Web 1 the scope of web pages are to just give out the information to the viewers as we see in TVs. But in Web 2.0 WebPages became dynamic in behavior, they provide information and also accepts data from the viewers and produce results based on those data. The current version of Web we are using is Web 2.0. In Web 2 the search engines use the keywords in the WebPages to show the results of the search query. That means the contents are index by means of keywords or tags, but not by the meaning.
Web 3.0 provides a better efficient searching of the web using the semantics of the content in the pages. That means the search engines work not with the keywords we use to search, but with the meaning of the search query we gave. So the main and most important feature of Web 3.0 is Semantic Web. I think you have got a rough idea about what I am talking about. It will be clearer if you see the example below.
Imagine I am going to Texas. And I want to know about the hotels, tourists spots etc there. In the present condition if I search the term ‘I am going to Texas’, I get the results page showing the websites containing the keywords I searched, but not useful for me. But in Semantic Web the search engine understands the semantics, that is the meaning of the search query and give results based on the semantics of the query. I think that might be more useful for me.
But some scientist thinks that implementing a semantic web is not possible as the semantic web need huge engineering work. But as always do there are some who thinks anything is possible if there is a will. Let’s wish to make Semantic Web a reality
