Semantic relationship learning device, semantic relationship learning method, and storage medium storing semantic relationship learning program

Abstract

A semantic relationship learning device includes processing circuitry to acquire positive example data pairs and to generate negative example data pairs by combining the language data, each of the negative example data pairs being formed with language data that are not in the predetermined semantic relationship with each other; to extract feature values from the negative example data pairs; to calculate a similarity level between the feature values; to classify the negative example data pairs into predetermined similarity level ranges or classifies learning-purposed negative example data pairs into predetermined similarity level ranges, thereby generating learning-purposed negative example data sets corresponding to the similarity level ranges; to select a learning-purposed negative example data set from the learning-purposed negative example data sets in an order according to a selection schedule; and to perform a machine learning process by using the selected learning-purposed negative example data set and the positive example data pairs.
