26. In a method for automated linguistic expression substitution on a digital data processor according to claim 22, the improvement in which said comparing step further comprises the step of detecting a disparity type resulting from differences in the number of characters represented by said suspect expression signal and by said alternate expression signal.
22. In a method for automated linguistic expression substitution on a digital data processor, the improvement wherein said digital data processor executes steps comprising A. accepting into said digital data processor a suspect expression signal representative of a linguistic expression consisting of characters, B. accepting into said digital data processor an alternate expression signal representative of a permissible linguistic expression consisting of characters, C. comparing within said digital data processor said suspect expression signal with said alternate expression signal and producing a disparity signal numerically representative of differences between a spelling of the linguistic expression represented by said suspect expression signals and a spelling of the linguistic expression represented by said alternate expression signal, said comparing step including the step of producing said disparity signal to be numerically representative of the type and magnitude of differences between said suspect expression signal and said alternate expression signal, said comparing step further including the steps of responding to the detection of transposition, character deletion, unmatched character, and character length disparity types for producing a signal indicative of the numerically-weighted structural significance of that detected type, and D. evaluating within said digital data processor a numerical value represented by said disparity signal for determining whether said alternate expression signal is substitutable for said suspect expression signal and for producing an output signal indicative thereof.
