A detailed description of the ANALYZE module of the MIND information system. This part of the system receives English sentences as input, segments them into words, and reduces the words to their ultimate lexical components through morphological analysis. Dictionary entries providing morphological, syntactic, and semantic information about the components are retrieved and amalgamated into word-level grammatical representations, and are then concatenated to form a bottom-level grammatical representation of the input sentence. This representation is passed to the PARSE module for further processing. Significant developments incorporated in the module include: (1) a sophisticated morphological analysis procedure, (2) a very efficient dictionary referencing organization, (3) powerful techniques for representing lexical generalizations, and (4) simple but effective means for morphological recombination of lexical components.
