1. A computer-implemented method for developing a parser, comprising: accessing a corpus of sentences; parsing the sentences with a computer to generate a structural description of each sentence using an existing parser, each structural description identifying noun phrases and a verb phrase from its corresponding sentence; transforming each structural description to a skeleton relation that only identifies one relationship between one subject and one verb in the skeleton relation's corresponding structural description's corresponding sentence, and one other relationship between one subject and the one verb in the skeleton relation's corresponding structural description's corresponding sentence; training another parser based on only the skeleton relations transformed from each structural description for use in identifying skeleton relations from sentences independent from the corpus of sentences; utilizing said another parser to parse another corpus of sentences.
