16. The data processing system of claim 15, which further comprises: said first processor means coupled to said second processor means, for receiving said new value for said adaptive probability weighting factor and computing a recognition means choice confidence factor in said data processing system, as a product of said character form confidence factor, said field type confidence factor, and said new value for said adaptive probability weighting factor, times a difference between said first confidence value and said second confidence value.
