ABSTRACT:
In a grammar checking system which includes first tagging a sentence as to parts of speech, underlying spelling is recovered by removing the effects of capitalization of a word so that appropriate inflection and or spelling can be suggested by the system. In order to determine the underlying spelling the system determines whether a noun is a proper noun through the utilization of a part of speech tagger and the utilization of part of speech trigram probabilities, with capitalized and uncapitalized versions of the word having different trigram probabilities. The system also establishes whether a word is an ordinary word as opposed to a proper noun or other intrinsically capitalized word. With the system further determining which of two interpretations of the word is the best one.
