【摘要】：當前,這個企業(yè)信息爆炸的時代,企業(yè)的規(guī)模越大,積累的信息也越多,信息的檢索與查詢工作也就越難以進行。目前許多企業(yè)己經(jīng)建立了自己的內(nèi)部網(wǎng)絡(luò)(Intranet),而且這樣的網(wǎng)絡(luò)規(guī)模越來越大,數(shù)據(jù)越來越多、種類也越來越豐富,導(dǎo)致的結(jié)果是用戶要在這些數(shù)據(jù)中找出自己感興趣的信息越來越困難,不借助搜索引擎做到這一點似乎變得越來越不可能。 所謂企業(yè)搜索是指對企業(yè)內(nèi)部以及部分企業(yè)相關(guān)的外部信息資源的搜索,它區(qū)別于一般的互聯(lián)網(wǎng)搜索,具有數(shù)據(jù)源多樣、數(shù)據(jù)結(jié)構(gòu)復(fù)雜、搜索結(jié)果精準、信息安全嚴格、檢索服務(wù)智能、搜索信息實時等特點。 本文采用J2EE架構(gòu),通過對全文搜索引擎Lucene的擴展以及Tika等中間件的使用,成功的構(gòu)建了企業(yè)搜索平臺。本系統(tǒng)是通過對企業(yè)內(nèi)外部多樣化信息進行基于定制任務(wù)的統(tǒng)一采集,并對采集到的海量信息進行智能化分析和有效整合后,再利用一套安全的基于角色的、統(tǒng)一可靠的訪問接口,為企業(yè)提供信息檢索服務(wù)。本系統(tǒng)專注于提高企業(yè)信息利用效率,提升企業(yè)產(chǎn)能和效益,全面幫助企業(yè)實現(xiàn)價值最大化。 本文首先介紹了項目背景、研究的主要問題；接下來介紹了系統(tǒng)實現(xiàn)過程中用到的相關(guān)技術(shù)；然后,本文從數(shù)據(jù)流的角度對系統(tǒng)進行了深入地分析；在系統(tǒng)設(shè)計部分,本文首先給出了系統(tǒng)的總體設(shè)計,然后根據(jù)系統(tǒng)功能的劃分給出了各個功能模塊的具體設(shè)計,接著給出了E-R圖和部分數(shù)據(jù)庫表結(jié)構(gòu)；在系統(tǒng)的實現(xiàn)部分,使用流程圖給出了系統(tǒng)各主要模塊的實現(xiàn)過程；然后對系統(tǒng)的單元測試、集成測試、系統(tǒng)測試的內(nèi)容進行了說明,并展示說明了運行效果；最后對本文工作進行總結(jié),并進一步展望了未來的工作。
[Abstract]:At present, in the era of enterprise information explosion, the larger the enterprise scale, the more information it accumulates, and the more difficult it is to retrieve and query information. At present, many enterprises have established their own internal networks, and the scale of such networks is getting larger and larger, with more and more data and more and more kinds of networks. As a result, it is becoming increasingly difficult for users to find the information they are interested in in the data, and it seems increasingly impossible to do so without the help of search engines. The so-called enterprise search refers to the internal and part of the enterprise related external information resources search, it is different from the general Internet search, with diverse data sources, complex data structure, accurate search results, strict information security, Search service intelligence, real-time search information and other features. In this paper, the enterprise search platform is successfully constructed by the extension of full-text search engine Lucene and the use of middleware such as Tika. This system is through the enterprise internal and external diversification information based on customized task of the unified collection, and the collected mass of information intelligent analysis and effective integration, and then use a set of safe role-based, Unified and reliable access interface to provide information retrieval services for enterprises. The system focuses on improving the efficiency of enterprise information utilization, enhancing the productivity and efficiency of enterprises, and comprehensively helping enterprises to achieve maximum value. This paper first introduces the background of the project, the main problems of the research; then introduces the relevant technologies used in the implementation of the system; then, this paper analyzes the system from the point of view of data flow; in the system design part, This paper first gives the overall design of the system, then according to the division of the system functions to give the specific design of each functional module, then gives the E-R diagram and part of the database table structure. Use the flow chart to give the implementation of the main modules of the system; then the system unit testing, integration testing, system testing content are described, and show the running results; finally, the work of this paper is summarized. The future work is further prospected.
