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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
