A method (and system) for associating an item with only less than ten
categories from a collection of more than hundred categories. Each
category includes a model, which determines a process. The process
determines a degree of closeness to a set of features of items. The
method includes receiving an item (e.g., document); and determining a set
of features (e.g., word, number, author) associated with the item. The
method also uses the set of features with two or more processes in
respective categories out of the collection of more than one hundred
categories to determine how well the set of features matches the two or
more categories. A step of forming a blended model from two or more
categories to derive a blended process is included. The blended process
yields a closer fit to the set of features of the item than that of any
single process of a category from the collection of categories. The
method associates the item to each of the two or more categories that
were used to form the blended process.
