**MovieLens 10M**

# MovieLens 10M

## About this network

This bipartite network contains ten million movie ratings from http://movielens.umn.edu/. Left nodes are users and right nodes are movies. An edge between a user and a movie indicates that the user has rated the movie with the rating value attached to the edge.
