GroupLens
=========

   GroupLens is a collaborative filtering system that helps you work
together with other people to find the quality news articles out of the
huge volume of news articles generated every day.

   To accomplish this the GroupLens system combines your opinions about
articles you have already read with the opinions of others who have done
likewise and gives you a personalized prediction for each unread news
article.  Think of GroupLens as a matchmaker.  GroupLens watches how you
rate articles, and finds other people that rate articles the same way.
Once it has found some people you agree with it tells you, in the form
of a prediction, what they thought of the article.  You can use this
prediction to help you decide whether or not you want to read the
article.
