Innovation has always been a part of evolution,which sometimes directly affect us sometimes not.Some important innovation that I can think of that directly affected me in last decade or so can be E-Mail,Cell phones,Search Engines(Google to be more specific).Google has now taken a integral part of our life(both professionally and personally)or to say has obtained ubiquity that we cannot even imagine life without it.The word googling has become such a cliche that Oxford should seriously think of adding it to the English dictionary.But in order to be master of googling you should know how to phrase your sentence so that you get the desired result(I still remember my lead in my first company gave me a hour of lecture as to how to phrase your text to get desired result).I am not making sense, hang on let me cite an example try searching the phrase “population of India” through your search engine then type “what is the size of India’s population” you will find that resultset fetched are not same(hmmmm) why? because it does not comprehend that both are one and same, as our human brain can do
Here emerges the semantic search which searches through the semantic web which might solve our problem.
Before we move on to the detail of the both lets see how the search engine works presently
How does Web Search Engines work

Web search engines are the superhero’s which search and retrieve information on the web. Most of them use crawler indexer architecture which use the crawler modules(Crawlers also referred to as spiders which are small programs that browse the web).They first retreive and store all the web pages that are present on internet, then indexes them depending upon the titles,heading,or meta tags.So when you hit the query in order to retrieve them ,they use this indexes and return the resultset which are relevant to your search.Again they have different algorithms for indexing and as well as giving importance to each object returned in the resultset(for e.g google uses page rank algorithm while others give importance to no. of times the phrase of search has been used in a particular web page……lets keep it short and not divulge into those details).In the end from common user’s perspective like me the usefulness of a search engine depends on the relevance or importance (to me)of the result set it gives back

What is semantic Web and Semantic Search

The Semantic Web will be new improved form of the current Web in which information will be given well-defined meaning, better enabling computers and people(us) to work in cooperation(i.e. by understanding each other). It is the idea of having data or objects on the Web defined and linked in a way that it can be used for more effective discovery, automation, integration, and reuse across various applications. In particular, the Semantic Web will contain resources corresponding not just to media objects (such as Web pages, images, audio clips, etc.) as the current Web does, but also to objects such as people, places, organizations and events. Further, the Semantic Web will contain not just a single kind of relation (the hyperlink) between resources, but many different kinds of relations between the different types of resources mentioned above.
Please have a look on to figure how Soubhagya Senapati object has a relation with profinia,with IDS,with Cricket.This denotes how all the objects are interrelated.This is what you can expect in future

The word semantic means(dictionary meaning) “of, pertaining to, or arising from the different meanings of words or other symbols”(i.e. trying to find out the meaning from a group of information)

The semantic search follows the concept of Research Searches. In many other cases, the user provides the search engine with a phrase which is intended to denote an object about which the user is trying to gather/research information.Actually there is no particular document which the user knows about that s/he is trying to get to. Rather, the user is trying to locate a number of documents which together will give him/her the information s/he is trying to find. This is the class of searches we are interested in.
Take for example you search for phrase “How to make a magazine” if there are objects(e.g web page) containing the phrases on the web then you are lucky else??? But semantic web will be storing the relation of the “How to make a magazine” with Editor,Articles,Web Designer,Content Designer,Writer,Printing House and your search will retrieve them . Just imagine the world with semantic web(simply amazing !!!!!!!!!!!!!!!!!!)

How does it impact the end user

Well how does it impact us, plain and simple as I have been telling all along it will make our life easier.It will take us from “todo” state to “done” state.Though true semantic Web is a bit far away(as the web is so hugh with so much of unstructured data) but companies have started using it.Google continues to use “smart indexing”, keywords/attributes, and behind the scenes semantics while Yahoo is using a more open approach, and is using content markup, open search and integrates vertical data feeds to enhance their results(being a Google fan I seldom use yahoo search so was unaware of it ).Ultimately, semantic search is about leveraging information to make the content on the semantic search results more structered .
