System for detecting and correcting contextual errors in a text processing system
First Claim
1. The method of detecting homophone contextual errors in a string of data segments in an information processing system comprising:
- (a) storing a table of homophones, each homophone having stored therewith a set of contextual usage rules specific thereto and at least one of said homophones having stored therewith one or more pointers to a table of other sets of contextual usage rules;
(b) scanning asid string for one of said homophones stored in said table of homophones;
(c) detecting a homophone in said string;
(d) accessing said contextual usage rules and any of said one or more pointers stored with said detected homophone, using said one or more pointers accessing any contextual usage rules in said table of other sets of contextual usage rules associated with said homophone;
(e) comparing data segments surrounding said homophone with said accessed contextual usage rules associated with said homophone; and
(f) indicating to an operator of said information processing system that a homophone has been found whose contextual usage rules do not compare with said data segments surrounding said homophone.

Abstract
A system for automatically proofreading a document for word use validation in a text processing system is provided by coupling a specialized dictionary of sets of homophones and confusable words to sets of di-gram and N-gram conditions whereby proper usage of the words can be statistically determined. A text document is reviewed word-by-word against a dictionary of homophones and confusable words. When a match occurs, the related list of syntactic rules is examined relative to the context of the subject homophone or confusable word. If the syntax in the immediate context of the homophone or confusable word conflicts with the prestored syntax rules, the homophone or confusable word is highlighted on the system display. The system then displays the definition of the highlighted word along with possible intended alternative forms and their respective definitions. The operator can examine the word used and the possible alternatives and make a determination as to whether an error has been made and if a correction of the text is required. If correction is required, the operator may cause the error word to be replaced by the desired word by positioning the display cursor under the desired word and depressing an appropriate key on the system keyboard.
