Spam Filtering with Naive Bayes - Which Naive Bayes?

TL;DR: An experimental procedure that emulates the incremental training of person- alized spam filters is adopted, and roc curves that allow us to compare the dierent versions of nb over the entire tradeo between true positives and true negatives are plotted.

Learning to Filter Spam E-Mail: A Comparison of a Naive Bayesian and a Memory-Based Approach

TL;DR: In this article, the authors investigate the performance of two machine learning algorithms in the context of ant-spam filtering and compare them to an alternative memory-based learning approach, after introducing suitable cost-sensitive evaluation measures.

Web Usage Mining as a Tool for Personalization: A Survey

TL;DR: This paper is a survey of recent work in the field of web usage mining for the benefit of research on the personalization of Web-based information services, focusing on the problems identified and the solutions that have been proposed.

A Memory-Based Approach to Anti-Spam Filtering

TL;DR: An extensive empirical evaluation of memory-based learning in the context of anti-spam filtering, a novel cost-sensitive application of text categorization that attempts to identify automatically unsolicited commercial messages that flood mailboxes, concludes that memory- based anti- Spam filtering for mailing lists is practically feasible, especially when combined with additional safety nets.
