【摘要】 随着Internet技术的发展,继数据挖掘技术成功地应用于传统数据库领域后,人们又开始尝试将其应用于其他类型的数据库。基于Web的数据挖掘技术(简称Web挖掘)就是在这种背景之下发展起来的。 本论文介绍了数据挖掘、Web挖掘技术和OLAP技术的理论发展及实际应用,并重点研究了数据挖掘中分类算法在Web挖掘中的应用,从而实现各类用户的个性化信息服务。论文主要内容有以下几部分组成:1.介绍数据挖掘技术的发展,挖掘过程及分类算法的实际应用情况。2.详细讨论Web挖掘技术。包括Web挖掘产生的背景,技术特点,Web访问挖掘的用户访问事务确定方法等。3.详细介绍了一种基于Web数据挖掘的分类算法。4.为了实现用户个性化信息服务,作者将上面提到的算法应用到了Web数据挖掘上,并对其中的决策树建树算法进行了改进。这一部分是本论文的重点。5.最后作者建立了在线个性化信息服务工具模型,提出下一步要做的工作并展望了Web挖掘技术未来发展方向。

【Abstract】 With the development of Internet technology, people begin toattempt to apply data mining technology, which has been applied in traditional database successfully, into the case of using other types of database. The data mining technology based on Web, which is called Web mining simply, occurs in this case.We introduces the development and application of data mining, Web mining and OALP technologies and focuses on the research of Web mining application using classification algorithm of data mining for individual information service. This paper consists of the following parts:1. introduction of development of data mining, mining procedure and application on classification algorithm.2. detailed discussion of Web mining technology, including the history and the characteristic of Web mining and methods of determining user access session, etc.3. detailed introduction of an online classification algorithm based on conceptual induction.4. the core of the paper is the improvement of the decision tree algorithm, which is applied in the Web data mining for the purpose of individual information service.5. finally the tool model for the online individual information service is offered, so do the next work and prospect the future of web data mining technology.
