The attributes of each data include the review ID, user ID, review, rating, the number of sympathy votes, the number of unsympathy votes, and timestamp. Especially, the number of symphy votes and that of unsympathy votes of each movie review, which had been evaluated by the other reviewers, can be used to judge the helpfulness of the review. The total number of the collected reviews is 233,928 and its total size reaches 135MB. Moreover, we collect all the historical ratings of the reviewer who writes the review for the target movie.
