“…Several studies were grounded based on the affecting factors, such as social media engagement, rewarding, point of sales data, and even cross-gaming behaviors. • Our study revealed a deficit of solid theoretical underpinnings in the current literature, as existing empirical literature mostly applied fewer theories and models, such as artificial intelligence theory (Ahmed et al, 2015); cross-gaming predictive models (Suh & Alhaery, 2014); Saaty scalebased model (Zhou et al, 2019); Bayes' theorem (Pantano et al, 2019); social media analytics framework (Ozturkcan et al, 2019); utility theory (Chiang & Yang, 2018); the social theory (Martens et al, 2016); parallel computing models (Guha & Kumar, 2018); duality theory (Gene et al, 2020); social representations theory (Pindado & Barrena, 2021); relationship marketing theory (Kitchens et al, 2018) and Bayesian approaches (Lin et al, 2020). • Concerning the context, authors identified that a large number of studies focused on the retailing and marketing sector, with fewer studies focusing on other industries, such as healthcare (Abraham et al, 2006); the apparel sector (Moisander et al, 2010); information technology (Lau, Li, & Liao, 2014); higher education (Duffy & Ney, 2015); the food industry (Fiore et al, 2017); finance (Lin et al, 2020); banking (Shirazi & Mohammadi, 2019) and the airline industry (Ma et al, 2019).…”
