Web Personalization and Mining Using Robust Fuzzy Clustering Methods

这是一个机构间合作项目，由巴尔的摩县马里兰州大学的Anupam Joshi和科罗拉多矿业学院的Raghu Krishnapuram开展。本研究的目标是开发可扩展的鲁棒技术来建模包含未知数量的重叠类别的噪声数据集，并将其应用于创建用于Web个性化和挖掘的软件工具。个性化有两个组成部分：（1）定制从网站传递给用户的内容;（2）探索可用的网页并对其进行分类。该方法包括开发新的实用的聚类算法相结合的模糊方法，强大的统计，与蒙特卡洛/自举技术建模未知数量的重叠集的存在离群值。由于许多Web对象，如URL，IP地址和网页不能表示的数字特征，新的技术来处理Web对象的语言和文本特征，以及分类或集群，通过使用合适的相似性措施，这些对象之间，正在探索。正在创建和验证一个用于网络个性化和挖掘的软件工具，该工具将所开发的算法纳入软件架构。该项目的结果将产生新的理论结果和有效的算法，用于从嘈杂的数据集同时估计未知数量的重叠类别的参数，以及将在网络上提供的网络个性化和挖掘工具。因此，预计该项目将对文件的搜索和提供方式产生重大影响。它将直接影响互联网和万维网的实用性和传播，并从总体上促进数字图书馆技术的发展。 http://www.cecs.missouri.edu/~joshi/web-mine/

This is an inter-institutional collaborative project carried out by Anupam Joshi at the University of Maryland, Baltimore County and Raghu Krishnapuram at the Colorado School of Mines. The goal of this research is to develop scalable robust techniques to model noisy data sets containing an unknown number of overlapping categories, and apply them to create a software tool for web personalization and mining. Personalization has two components: (1) tailoring the content delivered to the user from a web site; and (2) exploring the available web pages and categorizing them. The approach consists of developing new practical clustering algorithms by combining fuzzy methods, robust statistics, with Monte Carlo/bootstrapping techniques to model an unknown number of overlapping sets in the presence outliers. Since many web objects such as URLs, IP addresses, and web pages cannot be represented by numerical features, new techniques to handle web objects with linguistic and textual features, as well as to categorize or cluster them by using suitable similarity measures between such objects, are being explored. A software tool for web personalization and mining, which incorporates the algorithms developed into a software architecture, is being created and validated. The results of this project will generate new theoretical results and efficient algorithms for simultaneously estimating the parameters of an unknown number of overlapping categories from noisy data sets, as well as a web personalization and mining tool that will be made available on the web. Thus, this project is expected to have a significant impact on the way documents are searched for and delivered. It will directly influence the usefulness and spread of the Internet and WWW, and in general, will contribute to the digital library technology. http://www.cecs.missouri.edu/~joshi/web-mine/
