  • Patent number: 7233891
    Abstract: A method, computer program product, and apparatus for parsing consecutive sentences which includes tokenizing the words of the sentence and putting them through an iterative inductive processor. The processor has access to at least a first and second set of rules. The rules narrow the possible syntactic interpretations for the words in the sentence. After exhausting application of the first set of rules, the program moves to the second set of rules. The program reiterates back and forth between the sets of rules until no further reductions in the syntactic interpretation can be made. Thereafter, deductive token merging is performed if needed.
