Every generic rating is accompanied by a rating matrix. The first thing to understand is that if you don't want to deal with this level of complexity, you can ignore the matrix completely and judge a movie purely by the generic rating present as a number of stars between one and four. However, if you would like to attempt a more detailed analysis (and subsequent prediction), then the matrix is available.
The matrix is a 4x4 two-dimensional histogram of all the generic ratings submitted for a particular movie. The rows correspond to the four susceptibilities a person can use to describe themselves, and the columns correspond to the ratings submitted for the movie in question. The following examples will help you conceptualize the matrix:
The matrix can be used in the following manner. First, divide it into four quadrants (effectively 2x2 instead of 4x4). Brightness in each of the four quadrants then represents the following information:
The final point to be made about the matrix is that on a personal ratings page (but not the generic ratings page) one of the rows will be offset by small arrows, like this:
The arrows indicate the susceptibility row that the user in question specified when creating their account. In other words, that is the row which is most likely to represent or predict that user's reaction to the movie this matrix derives from. In the example shown above, the user specified a susceptibility of three when creating their account, and they are likely to react quite badly since other people with a similar susceptibility have reported ratings of three and four for this movie.
