Design And Implement Of The Chinese Search Engine

In recent years, with the development and modernization of the Internet, and the emergence of low-cost graphical user interface and large-capacity storage devices, the field of information retrieval has undergone tremendous changes. No one can accurately know how many pages on the network, while estimates are saying that the figure can exceeded 10 billion. To make use of the huge amount of data, the only way is to use some web search engines to automatically organize the data.Search engines is made to achieve the goal of storage, organization and access of the information items on the network. Search engines can be used to locate a huge number of information on network as well as some unknown information can be quickly found.Internet search engine is the core of information retrieval technology. At present, the search engines that is widely used on the Internet, including the Chinese search engines, has no less than ten, such as Google, head of the general purpose search engine, and various types of vertical Web search tools based on industry classification. However, there are still a long distance between the Chinese search engine and its similar products abroad, such as low coverage, the not high correction rate, the bad accuracy of retrieval, slow updating, unable to controlling the dynamic changes of network information, and difficulity on control and management of the content.Because of these problems, this paper based on Chinese search engine presents some optimization strategy on the retrieval object and the design of its own struction to solve the low correction rate and the low accuracy problems.This article makes a study on the basic architecture and technology of the general-purpose search engine and gaves a detailed descriptionon on the design methodology of how to make a real Chinese search engine based on Sirgin. This article especially illustrates how to achieve the internal database system of a search engine as well as showing the implements and algorithms of Castclose and SpRank technology which Sirgin has as its own.
