Research And Application Of Intelligent Search Engine In Enterprise

With traditional Internet search engine, users can retrieve a lot of useful information. However,the Internet search engine is for general users, which is not able to meet the search needs ofenterprise users. For enterprise users, the limitation of traditional search engine is reflected in twoaspects as follows. The recall ratio and precision ratio of the WEB search are too low, and it isunable to enable information retrieval over enterprise relational databases. With the rapiddevelopment of enterprise information, tailored enterprise search engine becomes a demand, and theresearch over enterprise search engine will become a research focus in the information field. Thusthis paper proposes a subject, named as “Research and Application of Intelligent Search Engine inEnterprise”. In this paper, the system architecture of search engine for enterprise is proposed, whichis adopted in the search engine system of Zhejiang Tobacco Industrial enterprise. The search enginesystem frame is proposed. The primary research contents of this article read as follows:1) The demand of enterprise users on search engine is summed up. And it determines thefunctions which should be realized by the enterprise search engine. One is to realize the efficientsearching of Intra-industry webpage. The second is to enable keyword-based information retrievalover relational databases, which allows users to acquire information from databases in the way ofcommon search engines instead of report forms. Thus the principles of Internet search engine aswell as keyword-based search over relational databases technology are studied in depth. In view ofthe malpractice existing in the present keyword-based retrieval mode, this paper puts forward akeywords semantic extension strategy based on ontology. The strategy is based on the previousresearch, which is improved. Dimension keyword and the choice factor of users are introduced.The strategy is more suitable for the search engine system in enterprise.2) Proposed enterprise search engine architecture. Articles mainly designed the three modulesof the system which are keywords preprocessing module, Intra-industry Web search module andkeywords query module over relational databases within enterprise. The design focused on themecrawler and keywords query module over relational databases within enterprise.3) At the end of this paper, the search engine system of Zhejiang Tobacco Industrial enterprise, whose development the author is taking part in, is taken as an example to verify the system schemepresented in this paper. Because of the urgency of time and the complexity of the system, thedevelopment of the system has not been finished. But it has already preliminary realized thefunctions, Intra-industry Web theme search and keywords query over relational databases withinenterprise.
