    Abstract: A method of detecting and correcting an error in a string of information signals. When each information signal represents a word, the method detects and corrects spelling errors. The method detects and corrects an error which is a properly spelled word, but which is the wrong (not intended) word. For example, the method is capable of detecting and correcting a misspelling of "HORSE" as "HOUSE" In the spelling error detection and correction method, a first word in an input string of words is changed to form a second word different from a first word to form a candidate string of words. The spellings of the first word and the second word are in the spelling dictionary. The probability of occurrence of the input string of words is compared to the product of the probability of occurrence of the candidate string of words multiplied by the probability of misrepresenting the candidate string of words as the input string of words. If the former is greater than or equal to the latter, no correction is made. If the former is less than the latter, the candidate string of words is selected as a spelling correction.

    Abstract: GUESS-AHEAD FEATURE FOR A KEYBOARD-DISPLAY TERMINAL DATA INPUT SYSTEM A guess-ahead feature for an interactive terminal having a keyboard and a display screen where input data is entered via the keyboard and displayed. Means are provided for continually evaluating input data to determine if it is the beginning of a string of data stored in the system memory. If the input data is determined to match the beginning of the string of prestored data, the complete string of stored data is displayed without moving the cursor. A function key is provided so that if the displayed complete string is the string the terminal operator desires to enter, the terminal operator can, by the depressing the function key, advance the cursor to the end of the string. If, however, the displayed string is not exactly as desired, the operator merely continues keying input data. YO979-024
