A systematic review of trends and gaps in the production of scientific knowledge on the sociopolitical impacts of emojis in computer-mediated communication

This systematic literature review analyses trends in original research on emoji use in computer-mediated communications (CMC) published between 2011 to 2021. In total, 823 articles were identified that met the search criteria. The mixed-method approach included qualitative coding of articles and frequency analysis by year, impact quartile, research topic and multidisciplinarity, as well as a cluster analysis to examine trends in sociopolitical research. The results show that Computer Science, Communications and Social Sciences disciplines accounted for largest proportion of original research on emojis and CMC in the time period analysed and that the degree of scientific impact increased significantly across the time series. In recent years, sociopolitical research has had higher than average growth and can be clustered into various groups based on two broad objects of study: "culture-identity" and "social exclusion". The study also identified significant knowledge gaps, particularly in relation to emoji standardization and its sociopolitical implications. Overall, multidisciplinary approaches are epistemologically constrained, Spanish-language production is low, and there is an almost complete absence of context appropriate methodologies. The study concludes that there is a need to for more sociopolitical research on emoji use in CMC and multidisciplinary approaches, a shift away from the hegemony of Anglocentrism, and greater questioning of the structural influences of standardization process on questions of cultural, identity and social exclusion.
