ARGUMENT-SHARING DISCRIMINATOR LEARNING APPARATUS, LANGUAGE KNOWLEDGE COLLECTING DEVICE, AND ANAPHOR/ABBREVIATION ANALYZER

摘要

PROBLEM TO BE SOLVED: To provide an argument-sharing discriminator learning apparatus for learning an argument-sharing discriminator capable of discriminating whether or not two predicates share an argument, and a language knowledge collection device efficiently collecting argument-sharing knowledge.SOLUTION: The argument-sharing discriminator learning apparatus includes: a processing unit 295 that selects a plurality of predicate pairs from text data in which anaphora/omission relationship has been annotated, and extracts a feature quantity for analyzing and discriminating respectively; a processing unit 296 that generates positive examples and negative examples for learning using the feature quantity according to the annotation; and a learning processing unit for learning an argument-sharing discriminator so as to represent whether the predicate pair to be input share the argument using the learning data. The argument-sharing discriminator having learned in that manner is applied to a text archive so as to efficiently collect the argument-sharing knowledge. Further, the argument-sharing knowledge is applied to the annotation of the anaphora/omission relationship so as to verify the annotation result.SELECTED DRAWING: Figure 7
