The research on emoji has become a hot topic in the academic field, and more and more scholars from the fields of computing, communication, marketing, behavioral science and so on are studying them. They not only have unique semantic and emotional features, but are also closely related to marketing, law, health care and many other areas. As a result, emoji, which are a set of expression symbols, came into being.Įmoji are used more and more frequently in network communication, and the way they are used is becoming more and more diversified as well. These expression symbols make up for the lack of non-verbal cues in CMC (Tossell et al., 2012 Negishi, 2014), and are very well-suited for social media communication (Barbieri et al., 2016c). To address this problem, communicators have devised new non-verbal cues, such as capitalization as a substitute for shouting, multiple exclamation points for excitement, and expression symbols for facial expressions (Harris and Paradice, 2007 Riordan and Kreuz, 2010). However, the lack of non-verbal cues such as facial expressions, intonation, and gestures in CMC can affect the transmission of information (Archer and Akert, 1977).
It has many advantages, including enhancing the continuity of individual communication (Juhasz and Bradford, 2016), improving the quality of relationships (Pettigrew, 2009 Perry and Werner-Wilson, 2011), and strengthening emotional communication (Derks et al., 2008b). With the widespread application of computing and the development of technology, computer mediated communication (CMC) is infiltrating daily life to a greater and greater extent.
