摘要： A knowledge representation expansion apparatus includes: a predicate-argument structure analyzing unit for extracting a predicate and at least one argument from a text using a meaning representation language; an ontology unit for representing knowledge using a knowledge representation language, which is a structured format understandable by a computer, and for extracting a second predicate corresponding to a first predicate, which is extracted from the predicate-argument structure analyzing unit; and a knowledge representation unit for representing knowledge extracted from the text using the first predicate, when the similarity of the first predicate and the second predicate is equal to or less than a threshold value.
