Claim 13:
14. A cause-effect sentence analysis device comprising:
at least one processor configured to:
obtain a text from a database and extract a plurality of cause-effect sentences from the text, wherein each cause-effect sentence includes a cause expression and an effect expression;
acquire information indicating a reference expression serving as a reference for analyzing a degree of similarity;
calculate, for the each cause-effect sentence, a cause similarity degree that is the degree of similarity between the cause expression included in the cause-effect sentence and the reference expression and an effect similarity degree that is the degree of similarity between the effect expression included in the cause-effect sentence and the reference expression, wherein at least one of the cause similarity degree and the effect similarity degree is calculated using a similarity degree model based on a vector representation;

select, from among the plurality of cause-effect sentences, a cause-effect sentence in which one of the cause similarity degree and the effect similarity degree is above a similarity threshold, and the other of the cause similarity degree and the effect similarity degree is below the similarity threshold;
assign a priority on the basis of the cause similarity degree and the effect similarity degree to the cause-effect sentence of which the cause similarity degree and the effect similarity degree are calculated by the at least one processor; and
assign the priority to a cause-effect sentence having an effect similarity degree that is above the similarity threshold and a cause similarity degree that is below the similarity threshold from among the plurality of cause-effect sentences, in an ascending order of the cause similarity degree.
