Abstract:
1. A computer-implemented method of classifying a working object among a plurality of categories, each of the plurality of categories having a category profile including a plurality of category statistical values, each of the plurality of category statistical values relating to a countable item of a set of countable items, the method comprising: providing a working object to be categorized; producing a working object profile for said working object by determining a frequency of occurrence in said working object of each countable item of the set of countable items; determining a first chi-square statistical value for each category of the plurality of categories, each of said first chi-square statistical values based on the sum of a plurality of relationships, wherein each of the plurality of relationships is based on the difference of a frequency of occurrence for a countable item in said working object profile and a corresponding one of the plurality of category statistical values of the corresponding category profile divided by the corresponding one of the plurality of category statistical values; and generating a categorization for said working object in the one of the plurality of categories having the lowest corresponding first chi-square statistic value.
