Collaborative filters help people make choices based on the opinions of other people. GroupLens is a system for collaborative filtering of netnews, to help people find articles they will like in the huge stream of available articles. News reader clients display predicted scores and make it easy for users to rate articles after they read them. Rating servers, called Better Bit Bureaus, gather and disseminate the ratings. The rating servers predict scores based on the heuristic that people who… 
Experiences with GroupLens: marking usenet useful again
TLDR
The original GroupLens work is extended by reporting on a significantly enhanced system and the results of a seven week trial with 250 users and over 20,000 news articles, and the accuracy of the predictions are assessed.
GroupLens: applying collaborative filtering to Usenet news
TLDR
The combination of high volume and personal taste made Usenet news a promising candidate for collaborative filtering and the potential predictive utility for Usenets news was very high.
Google news personalization: scalable online collaborative filtering
TLDR
This paper describes the approach to collaborative filtering for generating personalized recommendations for users of Google News using MinHash clustering, Probabilistic Latent Semantic Indexing, and covisitation counts, and combines recommendations from different algorithms using a linear model.
Applying Collaborative Filtering to Usenet News
newsgroups carry a wide enough spread of messages to make most individuals consider Usenet news to be a high noise information resource. Furthermore, each user values a different set of messages.
Bookmark Hierarchies and Collaborative Recommendation
TLDR
A semantic similarity measure for URLs that takes advantage both of the hierarchical structure in the bookmark files of individual users, and of collaborative filtering across users to build a recommendation and search engine from ranking algorithms based on popularity and novelty measures extracted from the similarity-induced network.
What should I comment: Recommending posts for commenting
TLDR
A collaborative filtering method which exploits the co-commenting patterns of the users to generate recommendations, and compare the method with traditional content-based filtering approaches is proposed.
Distributing information for collaborative filtering on Usenet Net News
As part of the Information Revolution," the amount of raw information available to computer users has increased as never before. Unfortunately , there has been a corresponding jump in the amount of
GroupLens for Usenet: Experiences in Applying Collaborative Filtering to a Social Information System
TLDR
The technology that enables us to work together to solve the information overload problem for each other is called collaborative filtering.
Comparing State-of-the-Art Collaborative Filtering Systems
TLDR
This study reviews the main collaborative filtering methods proposed in the litterature and compares them on the same widely used real dataset called MovieLens, and using thesame widely used performance measure called Mean Absolute Error (MAE).
Recommending for Groups in Decentralized Collaborative Filtering
TLDR
Two different approaches for generating movie recommendations to a group of people are proposed and an extension to the usual datastructure of rating vectors in form of weighting factors is introduced in order to be able to take into account different types of rating information.

Newsgroup Clustering Based On User Behavior - A Recommendation Algebra
TLDR
A scheme for users to peek at other users'' user models to extract information is proposed, in an information retrieval or information filtering domain.
Newsgroup Clustering Based On User Behavior | A Recommendation
User models are a tool for guiding system behavior in interactive systems, and their utility and properties, desirable and undesirable, have been investigated in this context. There are several ways
Using collaborative filtering to weave an information tapestry
TLDR
Tapestry is intended to handle any incoming stream of electronic documents and serves both as a mail filter and repository; its components are the indexer, document store, annotation store, filterer, little box, remailer, appraiser and reader/browser.
A learning approach to personalized information filtering
TLDR
Experimental results indicate that Newt can be personalized to serve some of the news ltering needs of the user, in particular, those that are more regular and predictable, and the basic framework for personalized information ltering agents is presented.

TLDR
The prospects and implications of automatic filtering of information, and the results suggest that the prediction of preferences can be straightforward when general categories for news articles are used; however, prediction for specific news reports is much more difficult.
