Essay on Knowledge Representation Using Semantic Web Techniques

The first versions of WWW ((what most people call “The Web”))) provide means for people around the world to exchange information between, to work together, to communicate, and to share documentation more efficiently. Tim Berners-Lee wrote the first browser (called WWW browser) and Web server in March 1991, allowing hypertext documents to be stored, fetched, and viewed. The Web can be seen as a tremendous document store where these documents (web pages) can be fetched by typing their address into a web browser. To do that, two im- portant techniques have been developed. First, a language called Hypertext Markup Languag (HTML) tells the computers how to display documents which contain texts, photos, sounds, visuals (video), and animation, interactive

Information in today 's world seems vast and often times limitless yet acquiring that information has become almost an effortless task since the arrival of the Internet. In the past 20 years this global system of interconnected computer networks has grown by leaps and bounds. The Internet has managed to provide the masses with an informational platform that runs 24 hours a day, 7 days a week. It delivers whatever we may need, desire or want to know about with just a few simple clicks or keystrokes. A technological medium that has become quite instrumental in our daily lives.

The semantic web is a vision created and promoted by Tim-Berners-Lee and the World Wide Web Consortium. In his article the Semantic Web in Scientific American (2001) Berners-Lee explains that The Semantic Web is not a separate Web but an extension of the current one, in which information is given well-defined meaning, better enabling computers and people to work in cooperation What Berners-Lee means by this is that in its current state, internet technology is not designed in a way in which computers and machines can interact with each other most efficiently. The primary reason for this disconnect is

The world as we know it has changed drastically in the past three decades, we are slowly but surely morphing into a worldwide community dependent upon computer technology. More specifically we rely on the Internet heavily for everything in our day to day lives. The benefits of expediency and the convenience afforded to those who utilize information systems their business dynamics is undeniable.

A website is used by different people for different uses. Each website can be evaluated for its usefulness by the general public based on certain criteria as discussed in this article.

how the World Wide Web

We are increasingly consolidating our information sources, forcing the Internet to be “our map and our clock, our printing press and our typewriter, our calculator and our telephone, and our radio and TV” (Carr).

In the universe of internet there are thousands of sites with different formats, objectives, specialties and services, and today on the web we can find the same products that can be found walking the city streets: newspapers, electronic stores, banks, grocery stores, transportation services, hospitals, pharmacies, gift shops and hundreds of department stores.

The World Wide Web consists of a collection of electronic documents in the form of web pages. These web pages have unique addresses called URL’s that show where to locate the web page on the World Wide Web. This essay will examine various definitions of URL’s and cookies, and why a web analyst should care about their importance.

“With an estimated 46.5 billion webpages indexed by Google alone by 2011, there is seemingly no end in sight for web growth” (DeRoche, October

It is a technologically advanced world, and today the internet is one of the most prominent mediums through which the companies across the globe for marketing their product and services to the potential customers. Today, for each and every company it is very important to have a strong presence over the internet. The websites are the best and the most effective medium that is utilized by the companies to be ahead of their competitor’s.

On March 2009, CERN, the European Organization for Nuclear Research celebrated the 
20th anniversary of the Web (CERN, 2009).With internet users accounting for 28.5% of the world population in June 2010 (Internet World Stats, 2011), the web's growth and use have become an integral part of modern day living whether for business or entertainment. Its impact and usage in today's world is even more remarkable considering its humble beginnings and origin.

The million dollar question is: what is the Semantic Web? The Semantic Web is not a completely new web that is going to replace the current web, it is simply and extension from the present web. The idea of Web 3.0 is for the information in the web to be understood and recognized by the computer. Today the web is a big global storage that stores files for humans to read, not computers, humans. This in what the Semantic Web is going to change by allowing computers to read and understand the information and data stored in the web.

The vision of the Semantic Web promises a kind Machine Intelligence, which can support a verity of user tasks like improved search engine or Question Answering (QA). Ontologies are needed for realization of the semantic web, which in turn depends on the ability of system to identify and take advantage of relationships that exist between and within ontologies. There are huge numbers of ontologies present on the web they need to be integrated for data integration. These ontologies are having different in representation, quality of data and larger sizes of ontologies, this lead to be problem during ontology mapping, on analyzing these problems and to introduce Multiagent mapping system. Main aim is to achieve heterogeneous data integration through semantic mapping of ontologies. this paper provide a mapping framework for Multiagent ontology having heterogeneous data in Semantic web and develop a question answering system from developed framework of ontology’s and improve performance by adding semantic relation interpreter which improves response time.

Following the success of Netscape and its web browser, Internet became a resource and communication platform idolized by many IT students in the universities. What started off as a hobby-cum-research[1] work by Jerry Yang (now Chief of Yahoo!) and David Filo (Co-founder of Yahoo!) for their Ph.D. dissertations; has evolved and became an Internet sensation over time. What they did was to compile all their favourite web links to form an online directory for easy navigation in the World Wide Web. The duo’s work immediately garnered a lot of attention from many surfers in the Internet world and before they realized it, Yahoo! became one of the most highly visited websites of all time. The duo saw the
