ABSTRACT:
Document form templates are grouped into groups of related form templates. The number of times a particular template is used by the system is counted for each group during a forms processing interval. Then when processing submitted forms, the method scans in a plurality of them in an aggregated submission. Forms recognition processing starts for a first form. The method begins searching for a form template to match the first form, starting with the most frequent group. If recognition of the first form is successful with the most frequent primary form template, then the method searches the group for the remaining submitted forms. If recognition of the first form is not successful with the most frequent group, then the method tries to match the first form with a template in the second most frequently processed primary group. In this manner, forms recognition of preprinted forms is managed, with the order of searching the template changed, in response to the frequency with which particular form types are processed.
