1. A method of packed meaning generation comprising the steps of: determining unordered rewrite rules containing pseudofacts based on the packed meaning representation and ordered rules based on the packed meaning representation; determining entries in a phrasal information structure based on a packed meaning representation and a lexicon and in which the entries are comprised of at least one of syntactic and semantic information; substituting semantic information into the phrasal information structure based on the unordered rewrite rules; determining combinations of entries in the phrasal information structure based on ordered rewrite rules, syntactic and semantic information; merging entries in the phrasal information structure based on syntactic and semantic information; determining source information associated with each determined combination based on the source information for each of the combined entries; and determining alternate phrases based on the source information.
