Abstract:
According to the present invention, the relationship between phrases can be accurately estimated while the cost of creating learning data is required. A learning data generation unit 62 extracts, on the basis of the dependency analysis result of an inputted text, paired phrases having a dependency relationship with a clause including a predetermined connection expression indicating the relationship between the phrases, and generates a triple set consisting of the extracted paired phrases and a relationship label representing the connection expression or representing the relationship indicated by the connection expression. A learning unit 63 learns a relationship estimation model for estimating the relationship between the phrases on the basis of the triple set generated by the learning data generation unit.
