The present invention provides a method for improving the efficiency of parsing text. Aspects of the invention include representing parse tokens as integers where a portion of the integer indicates the location in which a definition for the token can be found. In a further aspect, an integer representing a token points to an array of tokens that can be activated by the token. In another aspect, a list of pointers to partial parses is created before attempting to parse a next word in the text string. The list of pointers includes pointers to partial parses that are expecting particular semantic tokens.
