The future web generation is the semantic web which creates interaction and cooperation between the man and the computer through mobilization of data with determined ontological elements. In other words, semantic web is a kind of coding and information retrieval in a way that the machines (computer) would manage to process and comprehend data. In this article, information is collected by literature review regarding World Wide Web. Then, the necessity to create semantic web, advantages and problems of semantic web, using technologies such as eXtensible Markup Language (XML), Resource Description Framework(RDF), and web ontology, as the most important issues of semantic web, have also been taken into consideration. the results show that the ontologies are considered the spin of semantic web. Semantic web, using ontologies through providing conceptual structure for data, makes the ground work for correlated computers to intelligently find and furnish the researchers with the data. With the formation of semantic web, digital libraries can be based on meaning, and create major revolution in information retrieval. So access to online databases is provided.

One of the problems search engines have always faced with is matching the search query word-by-word with available documents in the search engine database. This leads to retrieving a large number of irrelevant documents and not retrieving all relevant documents. As a response to this weakness, the concept of “semantic web” has appeared which not only matches the terms but also searches according to: topicality, relationships among data, type of data, and other qualities. This article presents a description of semantic web followed by reference to its function with special emphasis on the “ontologies” which are the main components of semantic web applied for both meaning and concept matching. Then some issues are examined in the format of response and request which arise in semantic web. In addition Resource Description Framework (R.D.F), one of the components of semantic web, is discussed. It aims to establish a mechanism for the description of internet documents and resources.
