Morphological generation is the inverse of morphological anslysis, namely the process of converting the internal representation of a word to its surface form. For example, if our internal representations of the words mice and move are:
Root: MOUSE PartOfSpeech:Noun Number:Plural Root: MOVE PartOfSpeech:Verb Tense:Pastthen morphological generation would convert these to the character strings
The Assistant needed morphological generation to correct errors. Given the sentence I saw three blind mouse, one of the Assistant's error-correction rules might decide that, because of the qualifier three, mouse should be plural and not singular. From parsing the original sentence, the Assistant will have obtained a representation of the noun mouse. To correct the error, it must modify this representation so that it represents a plural, and then generate the appropriate surface form, mice.
