1. A computer-implemented method, comprising:

  • selecting a subset V of documents from a set U of documents;

    generating at least one Boolean combination of terms that partitions the set U into a plurality of categories that represent a generalized, statistically based model of the selected subset V wherein the categories are disjoint insofar as each document of U is included in only one category of the partition;

    generating a descriptive label for each of the disjoint categories from the Boolean combination of terms for that category;

    aggregating the descriptive labels to form a description of the subset V; and

    displaying the aggregating descriptive labels to a user.
