    User's provided ratings of the 1-5 scale or 0 if they haven't tried the product. Each user saw each item so in this sense the matrix is complete.

    Each user gave his ratings in one session.

    Usage Scenario

    Collaborative-filtering: 1. hiding some of known values 2. trying to predict them basing on others 3. check the error of prediction (RMSE, MSE, MAE or other).
