text implication determination device, text implication determination method, and program

摘要

For text implication determining unit 2, each of the first and second text for each predicate argument structure, using a word other than the word indicating the type of predicate arguments in the predicate argument structures, to generate a vector, the vector product a unit 21, the vector generated in each predicate argument structure for the first text, a second text is compared with the vectors generated for each predicate argument structure, based on the result of the comparison, first text identifying a combination of a predicate argument structure and predicate argument structure of the second text, the combined identification unit 22, for each combination, and obtains a feature amount, based on the characteristic quantity, the first text is the second determining whether the implication the text, I have a, the implication determining unit 23.
