1. An information process apparatus comprising: an extraction means which is configured to extract words in a predetermined word class from comments which predetermined users write about a predetermined item; a grouping means which is configured to group the predetermined users by performing a multivariate analysis using the words extracted by the extraction means, wherein the grouping means generates a matrix of the users and the words and performs a dimensional compression using the matrix, performs mapping of a result of the dimensional compression, and classifies the users into a plurality of groups by using a result of the mapping; a storage means which is configured to store the groups, the predetermined item, and the words in association with each other; a determination means which is configured to determine which group a user who is to write a comment belongs to when the user is to write the comment about the predetermined item; and a reading means which is configured to read from the storage means words which are associated with the group determined by the determination means and the predetermined item which the comment is to be written about.
