Usage Analysis of Skin Tone Modifiers on Twitter

Abstract

By using the skin tone modifier adopted in Unicode 8.0, it is possible to change the skin color of an emoji related to a person. In order to investigate the applicability to user profile estimation, this study analyzed the usage of skin tone modifiers on Twitter. As a result, the proportion of users using the same kind of skin tone modifiers as the one used on their profile for their own tweets is high. We also found that there are many replies to users who use skin tone modifiers of the same type.
