摘　　要：随着互联网信息多样化和爆炸式的发展,人们面临着"信息迷航"和"信息过载"的困扰;当代社会对信息检索的需求不仅仅局限在通用搜索引擎,更需要针对特定领域设计出个性化搜索引擎。通过分析研究网络搜索引擎的组成结构及利用Lucene构建搜索引擎的方法,在Lucene原有网页排序算法基础上,结合PageRank算法的思想和用户喜好权重,提出更具个性化的网页排序算法,以反馈给用户符合其个性化需求的搜索结果。在.Net开发平台,利用C#语言,结合几种开源API,完成了个性化网络搜索引擎系统的设计与实现。系统界面设计采用了XAML及Ajax技术,搜索结果显示模块采用异步传输技术,使用户界面更加友好。通过测试和分析,系统实现了个性化搜索,用户不翻页也可以查看全部搜索内容,用户的体验度得到了提升。下一步将增加爬虫对于网络错误信息的处理及对于病毒网站的过滤功能。With the explosive development of the Internet and information diversification, we face with the problem of “Information overload” and “Information Labyrinth”. The requirement of information re- trieval is more than general search engine, and the personalized search engine for specific areas is more necessary. Through analyzing the organization of network search engine and the method for construction of search engine by Lueene, based on the original webpage sorting algorithm, combined the PageRank al- gorithm and user preference weight, the paper presents a more personalized webpage sorting algorithm, to feedback the search results to meet the personalized needs of the customers. In the. Net development platform,using C#, combined with several open source APIs, the personalized network search engine is designed and accomplished. The design of system interface employs XAML and Ajax, and the search re- suits display module uses the asynchronous transmission technology to make the user interface more friendly. The testing shows the system can implement the personalized searching with better user experi- ence, and the users can read all search content with no scrolling. The next step would be to improve functionality of handling the error information on the Internet and filtering the virus website.
