## 2.1 Current Web & Limitations

Present World Wide Web is the longest global database that lacks the existence of a semantic structure and hence it becomes difficult for the machine to understand the information provided by the user in the form of search strings. As for results, the search engines return the ambiguous or partially ambiguous result data set; Semantic web is being to be developed to overcome the following problems for current web. 

- **The web content lacks a proper structure regarding the representation of information.** 
- **Ambiguity of information resulting from poor interconnection of information.** - **Automatic information transfer is lacking.** - **Usability to deal with enormous number of users and content ensuring trust at all levels.** 
- **Incapability of machines to understand the provided information due to lack of a** 
universal format. 

Hakia [7] is a general purpose semantic search engine that search structured text like Wikipedia. Hakia calls itself a "meaning-based (semantic) search engine" [8]. They're trying to provide search results based on meaning match, rather than by the popularity of search terms. The presented news, Blogs, Credible, and galleries are processed by hakia's proprietary core semantic technology called QDEXing [7]. It can process any kind of digital artifact by its Semantic Rank technology using third party API feeds [9]. 

## 3. Intelligent S**Emantic** Web 3.1 Intelligent Search Engines

Currently, a couple of Intelligent search engines are designed and implemented for different working environments, and the mechanisms that realize these search engine are distinct. 

Fu-Ming Hung and *Jenn-Hwa Yang* present an *intelligent search engine* **with semantic** technologies. This research has combine *description logic* **inference system and digital library** ontology to complete *intelligent search engine* [10]. **According to search engine mechanism,** 
presenting demands and a formula evaluating present related technology of that can solve and promote the efficiency of search engine, and formulating the demands of wisdom search engine. 

If uses Description Logic *Inference System* to integrate the digital library ontology to proceed 36
