【摘要】：当前,这个企业信息爆炸的时代,企业的规模越大,积累的信息也越多,信息的检索与查询工作也就越难以进行。目前许多企业己经建立了自己的内部网络(Intranet),而且这样的网络规模越来越大,数据越来越多、种类也越来越丰富,导致的结果是用户要在这些数据中找出自己感兴趣的信息越来越困难,不借助搜索引擎做到这一点似乎变得越来越不可能。所谓企业搜索是指对企业内部以及部分企业相关的外部信息资源的搜索,它区别于一般的互联网搜索,具有数据源多样、数据结构复杂、搜索结果精准、信息安全严格、检索服务智能、搜索信息实时等特点。本文采用J2EE架构,通过对全文搜索引擎Lucene的扩展以及Tika等中间件的使用,成功的构建了企业搜索平台。本系统是通过对企业内外部多样化信息进行基于定制任务的统一采集,并对采集到的海量信息进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、统一可靠的访问接口,为企业提供信息检索服务。本系统专注于提高企业信息利用效率,提升企业产能和效益,全面帮助企业实现价值最大化。本文首先介绍了项目背景、研究的主要问题；接下来介绍了系统实现过程中用到的相关技术；然后,本文从数据流的角度对系统进行了深入地分析；在系统设计部分,本文首先给出了系统的总体设计,然后根据系统功能的划分给出了各个功能模块的具体设计,接着给出了E-R图和部分数据库表结构；在系统的实现部分,使用流程图给出了系统各主要模块的实现过程；然后对系统的单元测试、集成测试、系统测试的内容进行了说明,并展示说明了运行效果；最后对本文工作进行总结,并进一步展望了未来的工作。
[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.
