Popis: Emojis are frequently used by people worldwide as a tool to express one’s emotional states, and have recently been applied to the research field to assess the same. However, the details of how they correspond to the human emotional states remain unidentified. Thus, this study aimed to understand how emojis are classified on the valence and arousal axes, and to examine the relationship between the former and the human emotional states. In an online survey of 1,082 participants, a nine-point scale was employed to evaluate the valence and arousal levels of 74 facial emojis. The cluster analysis revealed these emojis to be categorized into six different clusters on the two axes of valence and arousal. Further, the one-way analysis of variance indicated these clusters as having six valence and three arousal levels. From these results, each cluster was interpreted as (1) a strong negative sentiment, (2) a moderately negative sentiment, (3) a neutral sentiment with negative bias, (4) a neutral sentiment with positive bias, (5) a moderately positive sentiment, and (6) a strong positive sentiment. Therefore, facial emojis were found to comprehensively express the human emotional states.
