14. In a data processing system, including a plurality of character recognition means, an apparatus for selecting which one of said plurality of character recognition means to use for a character in a field in a document image, comprising: a memory for storing a character form confidence factor for each of said plurality of character recognition means; said memory storing a field type confidence factor for each of said plurality of character recognition means; said memory storing an adaptive probability weighting factor for each of said plurality of character recognition means; 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; a first processor means coupled to said memory and to at least one of said plurality of character recognition means, for computing a recognition means choice confidence factor, 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 said first processor means including means for 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.

The data processing system of claim 14, which further comprises: a second processor including accumulating means coupled to said means for selection for accumulating an error count of said first guess character; said second processor means computing a new value for said adaptive probability weighting factor for at least one of said plurality of character recognition means, by modifying said adaptive probability weighting factor with a value derived from said error count.
