recommender systems

An information filtering technology, commonly used on e-commerce Web sites that uses a collaborative filtering to present information on items and products that are likely to be of interest to the reader. In presenting the recommendations, the recommender system will use details of the registered user's profile and opinions and habits of their whole community of users and compare the information to reference characteristics to present the recommendations.

An example of a recommender system is WhatShouldIReadNext.com, a site where users can enter a title of a recent book they have read and enjoyed to see recommended books that they are likely to also enjoy.
