Analysis of Movie Rating Network

چکیده
The data used is MovieLens 1M from http://www.grouplens.org/node/73 which consists of 1 million ratings from 6000 users on 4000 movies. Due to huge number of nodes and edges, I only sample a small portion of the entire dataset which includes 11398 ratings from 86 users on 2154 movies during a week in 2000. Each user rates a movie using integer score ranging from 1 to 5 where larger score indicates more positive evaluation on this movie, resulting a directed and weighted edge pointing from the user to the movie. All edges originate from users to movies so there are no relationship between movies and friendship between users. The data formats are listed as follows.
