Recommender systems & collaborative intelligence

Recommender systems typically compare a user profile to reference characteristics in order to predict how a user would rate a new item based upon past preferences. The system may focus on attributes of the item (content-based approach) or the user's social environment (collaborative filtering approach), i.e. your friends bought this product so you might also like it.

Although recommender systems have traditionally been used for marketing, this page suggests that next generation recommender systems can be developed to augment collaborative intelligence.


Next generation recommender systems can be pattern recognizers,
combining content awareness with user profiling and geo-awareness to identify
how different participants with different profiles can more effectively participate
in a collaborative problem-solving ecosystem.


BACKGROUND. Examples of Successful Recommender Systems
Amazon recommends what books you might like to buy next based on your previous purchases and the purchases of others who bought the books you bought.

ChoiceStream culls user preferences to develop marketing strategies for online shopping, television (based on what TV shows are watched), and mobile phones (based on information such as ringtones and downloads.

MovieLens is a recommender system that uses collaborative filtering to provide you with movie recommendations based on your personal references. You preferences are matched with the preferences of other users with similar movie preferences. Visit the site for a tour of the service. MovieLens is a project of GroupLens Research.

Netflix recommends movies based on member reviews, critic reviews, popular rental lists and how you rate movies. Moviefinder and Movielens are other movie recommender systems.

Pandora™ emerged from the Music Genome Project™ and involves analysis of music by a team of musician-analysts, who study each song against nearly 400 attributes and makes this information available to the public. Users enter their favorite songs and artists into Pandora, then Pandora recommends similar music which is available through their site.

StumbleUpon gathers user ratings, using a collaborative opinion rating system to match users with websites based on their preferences and enabling users to rate sites for others to check.
