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.
