Description:
Abstract:
In this chapter we will study content-based filtering algorithms. We will describe the vector space model (vector space model) and the Term Frequency Inverse Document Frequency (TF-IDF) technique that weights the importance of a feature in a user's profile. Also, we will refer to recommendation systems using decision trees and the Bayesian classifier, which is a probabilistic prediction model. Then, we will give a detailed description of the basic methods (Gini index, Entropy, and χ2-statistic) for ranking the characteristics of a user's profile based on their importance for the decision tree algorithm.
