Word processor having spelling corrector adaptive to operator error experience
First Claim
1. In a word-processing system of the kind having operator input through a keyboard with a plurality of depressible keys, a spelling dictionary storing valid words within the system, a display, and an error-signal generator activated upon entry of an incorrect word as compared with the valid words of the dictionary;
- the combination of;
(a) a special key included on said keyboard,(b) storage means holding correction information of at least two kinds,(c) statistical means for controlling the selection order of said at least two kinds of correction information, comprising an individual counter for a respective one of said at least two kinds of correction information, each said counter storing a count dependent upon the relative extent of prior successful usage of each said kind in amending incorrect words previously entered by said operator;
(d) amending means operable to apply to said incorrect word the one of said kinds of correction information first selected by said statistical means, thereby producing therefrom a trial word for presentation on said display, said amending means being responsive to operator depression of said special key as a reaction to generation of an error-signal;
(e) means for adjusting said statistical means to select a second, next-in-order kind of correction information;
(f) a discrete key on said keyboard, depression of said discrete key rejecting said trial word presenting in said display and causing operation of said means for adjusting to supply said next-in-order kind of correction information to said amending means for application thereof to said incorrect word, thereby producing a new trial word for presentation on said display;
(g) a particular key on said keyboard, operator depression of said particular key indicating a trial word currently presented on the display is accepted as a replacement for said incorrect word; and
(h) incrementing means for unit incrementation of said individual counter for said next-in-order kind of correction information, said incrementing means responding to said operator depression of the particular key when said new trial word is presented in said display, whereby said statistical means is modified in accordance with the frequency of usage of each said kind of correction information.

Abstract
A word-processing system or memory typewriter has the usual keyboard, input display and/or printer; together with a spelling dictionary stored within the memory, and an error signal generating device activated upon entry of an incorrect word. For greater efficiency and ease of use by the operator, the memory also stores several kinds of correction information--e.g., typographical correction, transposition reversal, phonetic substitutions, etc.--suitable for amending the incorrect word to display a trial word which matches one from the above-mentioned stored dictionary, the amending occurring by depression of a special key whenever entry of an incorrect word activates the error-signal device. Statistical control of selection of the class of correction information is provided, the order of utilization of the various classes depending upon the relative extent of the operator'"'"'s prior successful usage of each class of information. If the trial word displayed is not satisfactory, the operator can depress the usual Index key 20I on the keyboard for presentation of yet another amended word matching the contents of the dictionary, and so on until the operator is satisfied with the one presented and signals the system to print that choice. If a match cannot be obtained with any of the information, the display indicates this fact to the operator.
