Implication determining device, implication determining method and implication determining program determining if hypothesis is a new fact

摘要

To provide an implication determining device, an implication determining method, and an implication determining program capable of improving implication determination performance. A new fact determination unit determines whether a given hypothesis is a new fact that indicates a first revealed fact in a hypothesis implied sentence that is a sentence implying the given hypothesis based on a specific expression written in the hypothesis implied sentence. An implication determination unit determines whether the given hypothesis is implied in a sentence to be determined that is a sentence to be determined whether the hypothesis is included.

主权项

1. An implication determining device having a processor for implementing units comprising:
a new fact determination unit configured to determine whether a given hypothesis is a new fact indicating a first revealed fact in a hypothesis implied sentence implying the hypothesis based on a specific expression written in the hypothesis implied sentence; and an implication determination unit configured to determine whether the given hypothesis is implied in a sentence to be determined that is a sentence to be determined whether the hypothesis is included, wherein the new fact determination unit determines whether a given hypothesis is a new fact with a clue of the specific expressions included in a document, and wherein, when it is determined that the given hypothesis is the new fact in the hypothesis implied sentence, the implication determination unit compares a date and time of occurrence of the sentence to be determined and a date and time of occurrence of the hypothesis implied sentence implying a hypothesis which is determined as the new fact, and determines whether the sentence to be determined implies the given hypothesis.
