This study focuses on Dixit, a game of Imperfect-Information Game. In this game, the parent player selects a card from his hand and puts it face down with a hint. The other players put card related to the hint face down from their hands. The other players guess the parent's card from the hint. If all the players can guess correctly on an easy hint, or if none of the players can guess correctly on a difficult hint, the parent player cannot score points. It is important for the parent player to control the relevance of the cards and hints. The analysis of such ambiguous hints is useful for implementing Dixit game AI and understanding human cognitive characteristics. Previous studies have not been able to study the control of relevance. In this study, we annotated and evaluated the relevance scores of cards and hints.
