Research And Implementation On The Professional Meta-Search Engine

With the rapid growth of Internet, more and more people use the search engines as main means of access to information. How to faster, more accurate access to specific network information, become the focal point of the search engines' study. Professional search engine offers professional information for users, which in line with the needs, in recent years has made rapid development.Based on in-depth analysis of the independent search engines and meta-search engines, and the distinction between their respective advantages and disadvantages, the Paper constructs a meta-search engine in the field of training. The meta-search engine using the results which returned from the independent search engine, it can't obtain much useful information from the results, to evaluate meta-search engine results' professional relevance, it must exploit more information. In this paper, it fully analyses the websites, which is based on genetic algorithm. Finally, the Paper designed and implemented the algorithm, and analyzed the results.Based on the above algorithm, design and implementation a professional search engine using the sequencing results which produced by the algorithm, the paper described in the design and realization of the process of the realization details. Finally, analysis and evaluation the returned results...
