| At present, people mainly through the search engine to obtain the information you needin the network, with the rapid growth of network information; people’s dependence on searchengine technology is bigger than before. But, instead of general search engine search resultscannot have satisfied in some field of high precision retrieval requirements. In depth retrievalis limited to a professional in the field of retrieval, accuracy and completeness of generalsearch engine is difficult to let customer satisfaction. Therefore, the use of vertical searchengines, a field of professional and in-depth queries, to give the user returns to high accuracyand relevance of the results becomes extremely important.This dissertation based on Lucene and Heritrix technology, combined with this, the statusof college students’ employment recruitment information, and acquisition of onlinerecruitment information, analysis of demand background, design and implement recruiting thecollege graduates employment information platform in the search engines. Main work is asfollows:First, in recent ten years in our school employment release recruitment information inrecruitment information and network combined with the actual needs of students as theresearch object in the requirements analysis, preliminary divided into the functionalarchitecture and design of this system framework.Second, we analyzed the Lucene indexing and retrieval functions, and on this basis isestablished based on the university recruitment information vertical search engine’s index andretrieval.Third, heat set up according to the network and the user has input words related to theprofessional library in clausal structure, using predictive theme of efficient algorithms,improve the accuracy of the search.Last, the system development environment is Windows XP, Tomcat, JSP and SQLServer.Practice shows that, the design of the vertical search engine for recruitment information inthis research is feasible; the system had met the basic design goal. |
