1. A method in a computer system for bootstrapping statistical processing into a rule-based parser for parsing input strings of natural language text using a set of conditioned rules, the method comprising the steps of:

  • (a) operating the parser such that the parser attempts to apply a subset of every applicable rule of the parser to each input string;

    (b) compiling statistics indicating the likelihood of success of each rule of the parser, based on the success of each rule when applied in step (a); and

    (c) operating the parser such that the parser applies at least one of the rules of the parser in descending order of the likelihood of success indicated by the statistics compiled in step (b).
