【摘要】：随着网络技术的飞速发展和电脑设备的普及,人们的生活、工作已经越来越不能离开网络,网络上的信息也是呈指数级的增多,为了帮助用户从海量的信息中到找到他们所需要的那部分信息,搜索引擎技术应运而生,并迅速成为人们不可或缺的信息查找工具,在短时间内风靡全球。搜索引擎技术的使用在很大程度上解决了人们查找信息的困难,但它也存在许多缺陷：搜索引擎反馈给用户的结果越来越多,而且对所有的用户一视同仁,没有针对性,其中的很多信息是用户并不需要的,这样的反馈结果使得用户耗费大量时间都可能找不到自己需要的信息,因此改善用户的查询体验以便于用户从海量的网络信息资源中得到自己所需的内容,必然会成为搜索引擎技术发展的一个重要方向,个性化搜索引擎的正是基于这一思想提出的。本文围绕个性化搜索引擎的应用展开,从分析搜索引擎用户的角度入手,介绍了搜索引擎技术的发展,个性化搜索引擎技术的原理,研究的现状和存在的问题,并提出了个人认为的预期发展,对现有的应用提出了一些改进方法,研究工作具有一定的理论性和实用性。本文的研究重点为以下几个方面： 1.用户信息的收集和分析。要想达到“个性化搜索”的目的,必须能通过用户上网留下的痕迹来收集到用户的有效信息,并利用这些信息分析出用户的兴趣、上网习惯等,以用于与搜索结果匹配。 2.如何对现有的搜索引擎的进行改进以达到个性化搜索结果的目的。目前使用的主流搜索引擎如百度、谷歌等虽然有其不足之处,但从技术的实现等方面去考虑,个性化的过程不会马上能够实现,必然是在目前的基础上循序渐进的进行,那么对目前的搜索引擎的一些改进可以达到较好的效果。 3.研究开源全文检索工具Lucene,使用Lucene进行索引与检索。
[Abstract]:With the rapid development of network technology and the popularization of computer equipment, people's life and work have become more and more unable to leave the network, and the information on the network is also increasing exponentially. In order to help users from the mass of information to find the part of information they need, search engine technology emerged as the times require, and quickly become an indispensable information search tool, in a short period of time popular around the world. The use of search engine technology has largely solved the difficulty of finding information, but it also has many defects: search engine feedback to users more and more, and the same to all users, not targeted, Much of this information is not needed by the user, and such feedback results in the possibility that users will not be able to find the information they need for a great deal of time. Therefore, improving the user's query experience so that users can get the content they need from the massive network information resources will inevitably become an important direction in the development of search engine technology. Personalized search engine is based on this idea put forward. Based on the application of personalized search engine, this paper introduces the development of search engine technology, the principle of personalized search engine technology, the status quo of the research and the existing problems from the point of view of analyzing the users of the search engine. The author also puts forward the expected development of personal opinion, and puts forward some improved methods for the existing application. The research work has certain theory and practicability. This paper focuses on the following aspects: 1. Collection and analysis of user information. In order to achieve the goal of "personalized search", we must be able to collect the effective information of the user through the traces left by the user on the Internet, and use this information to analyze the interests and habits of the user, etc., in order to match the search results. 2. How to improve the existing search engine to achieve the goal of personalized search results. The mainstream search engines currently used, such as Baidu and Google, have their shortcomings, but considering the realization of technology and other aspects, the process of individuation will not be realized immediately. It is bound to be carried out step by step on the current basis. So some improvements to the current search engine can achieve better results. 3. This paper studies the open source full-text retrieval tool Lucene and uses Lucene for indexing and retrieval.
