International journal of Web & Semantic Technology (IJWesT) Vol.2, No.1, January 2011 results from blogs (if available) or other discussion boards. The user cannot have a satisfaction with these results due to lack of trusts on blogs etc. To overcome this problem in search engines to retrieve relevant and meaningful information intelligently, semantic web technology deals with a great role [3]. Intelligent semantic technology gives the nearer to desired results by search engines to the user. In this paper, we will make a preliminary survey over the existing literature regarding intelligent semantic search engines and semantic web search. By classifying the literature into few main categories, we review their characteristics respectively. In addition, the issues within the reviewed intelligent semantic search methods and engines are analyzed and concluded based on perspectives.

Information retrieval by searching information on the web is not a fresh idea but has different challenges when it is compared to general information retrieval. Different search engines return different search results due to the variation in indexing and search process. Google, Yahoo, and Bing have been out there which handles the queries after processing the keywords. They only search information given on the web page, recently, some research group's start delivering results from their semantics based search engines, and however most of them are in their initial stages. Till none of the search engines come to close indexing the entire web content, much less the entire Internet. Current web is the biggest global database that lacks the existence of a semantic structure and hence it makes difficult for the machine to understand the information provided by the user. When the information was distributed in web, we have two kinds of research problems in search engine i.e. 

 **How can a search engine map a query to documents where information is available but** 
does not retrieve in intelligent and meaning full information? 

 **The query results produced by search engines are distributed across different documents** 
that may be connected with hyperlink. How search engine can recognize efficiently such a distributed results? 

Semantic web [4] [5], can solve the first problem in web with semantic annotations to produce intelligent and meaningful information by using query interface mechanism and ontology's. Other one can be solved by the graph-based query models [6]. The Semantic web would require solving extraordinarily difficult problems in the areas of knowledge representation, natural language understanding. **The following figure depicts the semantic web frame work it also referred as** the semantic web layercake by W3C.
