In this chapter a review of current psychological models of the decision-making process are presented. Web usage mining is the analysis of web users’ browsing activity by means of machine learning techniques. Accordingly, web usage patterns can be used for analyzing web user preferences. The process of knowledge discovery in databases (KDD) [9] consists of data pre-processing (filtering and transformation), data mining, and interpretation and evaluation. Once data have been consolidated (WebWarehouse) [95], specific machine learning algorithms are applied in order to extract patterns regarding the usage of the web site.

24 G. D. 1 Relevance Feedback and Explicit Ratings To discuss the details that surround the relevance feedback from explicit rating and how to include that in a particular application, let’s think about the use case where a particular end user is looking for a set of objects given an input query q, and the feedback is explicitly returned for the results obtained. In this context, the Rocchio algorithm for relevance feedback is one of the most used methods. However, to deal with uncertainty and and static values which could dynamically change the relevance and its parameters’ likelihood, further approaches based on probabilistic methods have been proposed.
