Description

Format:

Ratings are real values ranging from -10.00 to +10.00 (the value "99" corresponds to "null" = "not rated"). One row per user The first column gives the number of jokes rated by that user. The next 100 columns give the ratings for jokes 01 - 100. The sub-matrix including only columns {5, 7, 8, 13, 15, 16, 17, 18, 19, 20} is dense. Almost all users have rated those jokes (see discussion of "universal queries" in Eigentaste: A Constant Time Collaborative Filtering Algorithm. Ken Goldberg, Theresa Roeder, Dhruv Gupta, and Chris Perkins. Information Retrieval, 4(2), 133-151. July 2001.).
