Claim One:
1. In a data processing system, including a scanner, a plurality of character recognition means, a recognition station processor and a monitoring and correction station processor, a method for selecting which one of said plurality of character recognition means to use for recognizing a character in a field in a document image, comprising the steps of: generating a character form confidence factor in the recognition station processor, for each of said plurality of character recognition means; generating a field type confidence factor in the recognition station processor, for each of said plurality of character recognition means; inputting an adaptive probability weighting factor from said monitoring and correction station processor to said recognition station processor, for each of said plurality of character recognition means; generating a first guess character and first confidence value and a second guess character and second confidence value, using each of said plurality of character recognition means; computing a recognition means choice confidence factor in said recognition station processor, as a product of said character form confidence factor, said field type confidence factor, and said adaptive probability weighting factor, times a difference between said first confidence value and said second confidence value; and selecting one of said plurality of character recognition means in said data processing system, having a maximum value for said recognition means choice confidence factor.
