Abstract: An information processing device according to the present invention includes: a memory; and a processor coupled to the memory. The processor performs operations. The operations includes: generating, based on language data, a predicate argument structure including a predicate and an argument being an object of the predicate; generating first data indicating co-occurrence of the predicate and the argument in the predicate argument structure; decomposing the first data into a plurality of pieces of second data including fewer elements than elements included in the first data, and generating, based on the second data, third data including potential co-occurrence of the predicate and the argument; selecting the predicate argument structure by using the first data and the third data, and calculating, by using the third data, a score for a pair of the predicate argument structures including the selected predicate argument structure; and selecting the pair, based on the score.

Abstract: An information processing device according to the present invention includes: a memory; and at least one processor coupled to the memory, the processor performing operations, the operations comprising: providing, based on a first reliability score being a value representing a degree of a relationship between an instance candidate being a candidate for an instance that is data included in a category being a set of predetermined data and a pattern being a characteristic expression in the predetermined data, a first label for at least a part of the instance candidates; and updating the first reliability score of the instance candidate provided with the first label.
