First Claim
Patent Images
1. A computer readable medium having stored thereon instructions which, when executed, cause a computer to perform a method of processing a natural language input, comprising:
- identifying a plurality of N-best part-of-speech (POS) sequences corresponding to the natural language input;
identifying a likely base noun phrase (baseNP) sequence based on the N-best POS sequences identified; and
outputting the likely baseNP sequence.

Abstract
A system and method identify base noun phrases (baseNP) in a linguistic input. A part-of-speech tagger identifies N-best part-of-speech tag sequences corresponding to the linguistic input. A baseNP identifier identifies baseNPs in the linguistic input using a unified statistical model that identifies the baseNPs, given the N-best POS sequences.

10. A computer readable medium storing instructions which, when executed by a computer, cause the computer to perform a method of processing a linguistic input, comprising:
-
identifying a plurality of N-best part-of-speech (POS) sequences corresponding to the linguistic input;
identifying one or more base noun phrases (baseNPs) for each of the N-best POS sequences to form a plurality of different possible baseNP sequences corresponding to each of the POS sequences;
for each baseNP sequence, identifying whether it is a likely baseNP sequence based on a probability of the associated POS sequence and a probability of the baseNP sequence, given lexical information indicative of a position of words in the linguistic input relative to the baseNPs identified in the baseNP sequence; and
outputting the likely baseNP sequence identified. - View Dependent Claims (11, 12, 13)
