Textual entailment recognition apparatus, textual entailment recognition method, and computer-readable recording medium |
摘要 |
A textual entailment recognition apparatus (2) includes a vector generation unit (21) that generates, for each of first and second texts, a vector for each predicate-argument structure by using a word other than a word indicating a type of argument of a predicate in the predicate-argument structure; a combination identification (22) unit that compares the vector generated for each predicate-argument structure for the first text and the vector generated for each predicate-argument structure for the second text, and identifies combinations of the predicate-argument structures of the first text and the predicate-argument structure of the second text based on a result of the comparison; and an entailment determination unit (23) that obtains a feature amount for each of the identified combinations, and determines whether the first text entails the second text based on the obtained feature amounts. |

1. A textual entailment recognition apparatus for determining whether a first text entails a second text, comprising:
a vector generation unit that generates, for each of the first text and the second text, a vector for each predicate-argument structure of the first text and the second text by using a word other than a word indicating a type of argument of a predicate in the predicate-argument structure; a combination identification unit that compares the vector generated for each predicate-argument structure for the first text and the vector generated for each predicate-argument structure for the second text, and identifies combinations of the predicate-argument structures of the first text and the predicate-argument structure of the second text based on a result of the comparison; and an entailment determination unit that obtains a feature amount for each of the identified combinations, and determines whether the first text entails the second text based on the obtained feature amounts.
