1 New Emoji Requests from Twitter Users: When, Where, Why, and What We Can Do About Them YUNHE FENG, University of Tennessee, Knoxville, USA ZHENG LU, University of Tennessee, Knoxville, USA WENJUN ZHOU, University of Tennessee, Knoxville, USA ZHIBO WANG, Wuhan University, China QING CAO∗, University of Tennessee, Knoxville, USA As emojis become prevalent in personal communications, people are always looking for new, interesting emojis to express emotions, show attitudes, or simply visualize texts. In this study, we collected more than thirty million tweets mentioning the word “emoji” in a one-year period to study emoji requests on Twitter. First, we filtered out bot-generated tweets and extracted emoji requests from the raw tweets using a comprehensive list of linguistic patterns. To our surprise, some extant emojis, such as fire and hijab , were still frequently requested by many users. A large number of non-existing emojis were also requested, which were classified into one of eight emoji categories by Unicode Standard. We then examined patterns of new emoji requests by exploring their time, location, and context. Eagerness and frustration of not having these emojis were evidenced by our sentiment analysis, and we summarize users’ advocacy channels. Focusing on typical patterns of co-mentioned emojis, we also identified expressions of equity, diversity, and fairness issues due to unreleased but expected emojis, and summarized the significance of new emojis on society. Finally, time- continuity sensitive strategies at multiple time granularity levels were proposed to rank petitioned emojis by the eagerness, and a real-time monitoring system to track new emoji requests is implemented.
