Challenges and New Requirements In Semantic Web Maathu Michael (Department of CSE, Amaljyothi College of Engg. Kanjirapally) The World Wide Web (WWW) has changed the way people communicate with each other, how information is disseminated and retrieved, and how business is conducted. After the introduction of Semantic Web concept in 2001by Tim Berners-Lee there have been lots of efforts and researches to realize the Semantic Web goals. The term Semantic Web comprises techniques that promise to dramatically improve the current WWW and its use. An alternative approach is to represent Web content in a form that is more easily machine- processable and to use intelligent techniques to take advantage of these representations It is important to understand that the SemanticWeb will not be a new global information highway parallel to the existing World Wide Web; instead it will gradually evolve out of the existing Web. Semantic web affords to present information of World Wide Web, databases and other structured repositories in a uniform composition which is useable by other applications. In this paper a short overview of the Semantic Web status will be presented and the future work and extension points will be discussed. Keywords:Ontology, RDF,OWL,Web Services 1. Overview The Semantic Web (SW) is viewed as the next generation of the Web that enables intelligent software agents to process and aggregate data autonomously. Current web which can be assumed to be the biggest global database lacks the existence of a semantic structure to keep the interdependency of its components and as a result the information available on web is mostly human understandable. The original vision of the Web was much more ambitious than the reality of the existing (syntactic) Web:“... a goal of the Web was that, if the interaction between person and hypertext could be so intuitive that the machine-readable information space gave an accurate representation of the state of people's thoughts, interactions, and work patterns, then machine analysis could become a very powerful management tool, seeing patterns in our work and facilitating our working together through the typical problems which beset the management of large organisations.”Tim Berners-Lee. The World Wide Web (Berners-Lee, Cailliau & Groff, 1992; Berners-Lee, 1999) has changed the way people communicate with each other and the way business is conducted. It lies at the heart of a revolution which is currently transforming the developed world towards a knowledge economy (Neef, 1997), and more broadly speaking, to a knowledge society. Most of today's Web content is suitable for human consumption. Even Web content that is generated automatically from data bases is usually presented without the original structural information found in data bases. Typical uses of the Web today involve humans seeking and
