1. A system for creating classes for classifying digitized documents, the system comprising: a processor-based document management system comprising at least one processor coupled to a memory executed on a computer system and configured to: generate a plurality of word pairs, each word pair comprising a word from a first digitized document, and a corresponding word from a second digitized document; compute for each word pair first location information for the word that indicates a location of the word in the first digitized document relative to other words in the first digitized document; compute for each word pair second location information for the corresponding word that indicates a location of the corresponding word in the second digitized document relative to other words in the second digitized document; compare the first and second location information; and create one or more classes responsive to the comparison to classify digitized documents similar to the first digitized document, and to classify digitized documents similar to the second digitized document.
