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.

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. - View Dependent Claims (2, 3, 4, 5)

6. A non-transitory computer-readable storage medium having instructions that develop a parser for use in natural language processing, the instructions comprising:
-
an existing parser comprising a statistical parser that parses a corpus of sentences and generates a structural description of each sentence, each structural description identifying noun phrases and a verb phrase from its corresponding sentence a training module 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; and
training another parser based only on the skeleton relations transformed from each structural description for use in identifying skeleton relations from sentences independent from the corpus of sentences. - View Dependent Claims (7, 8, 9, 10)

11. 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 corresponding 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 by replacing a link in the skeleton relation'"'"'s corresponding structural description between a subject and an object with two links, one link between the subject and the verb and the other link between the object and the verb; 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 to identify skeleton relations therein.
