System and method for document grouping

Abstract

Computer-based techniques for grouping documents are described herein. Documents may be grouped, organized, named, and/or indexed by their document character features. Document character features may comprise character counts, character difference counts, missing character counts, and any combination thereof. The comparison of documents may use a comparison threshold value for grouping documents. Documents may be processed in any language.

What is claimed is: 
     
         1 . A computer-implemented system for grouping documents, the system comprising:
 a non-transitory document storage device comprising computer memory configured to store a plurality of document data items, each document data item associated with a distinct document,
 wherein the document data items each comprise a plurality of character counts, each character count corresponding to a number of times a specific character type occurs within the distinct document associated with each document data item in the plurality of document data items; 
   a computerized matching unit comprising one or more hardware processors,
 wherein the computerized matching unit is adapted to access the non-transitory document storage device and generate a grouping comprising: 
 a first indicator of the plurality of character counts in common between two or more of the plurality of document data items; 
 a second indicator of the plurality of character count variances between two or more of the plurality of document data items; 
 a third indicator of missing characters between two or more of the plurality of document data items; and 
 a combined indicator based on the first indicator, the second indicator, and the third indicator, compared to a threshold indicator; and 
   a matching reporting unit adapted to report the grouping generated by the computerized matching unit to a user.
