Abstract: A morphological analysis method is described. In one aspect of the invention, the method includes the steps of breaking a word into potential base-affix pairs, modifying the base of each base-affix pair into possible roots, accessing each lexical entry of each root in a lexicon, deriving a lexical entry for a root if the lexical entry is not provided in the lexicon, retrieving the derivation information for each affix from the entry, applying the derivation information to the entry, and returning all derived entries.

Abstract: A sense discrimination system and method are described. One aspect of the present invention includes a method for performing sense discrimination, a token stream including a token wherein each sense of each lexical entry may be marked with a positive or negative morphology preference, each sense of each entry may be marked with relevant contexts, and each sense of each entry may be marked with a positive/negative status being provided, at least a portion of one parse tree and at least a portion of one head tail matrix also being provided. The method includes the steps of converting each preference marking into a raw numeric score, scoring the sense preference information, determining a best sense of a lexical entry from the sense preference information score, and inserting a designation for the best sense into a respective token.
