“…Personas, as imaginary people describing real user segments , are considered a powerful technique for user understanding and usercentric design in human-computer interaction (HCI). Personas are relevant and potentially useful for researchers and practitioners facing user-centric decision-making tasks in a variety of industries and application domains, including software development (Aoyama, 2007;Hang Guo & Razikin, 2015), design (Goodman-Deane et al, 2018;Miaskiewicz & Luxmoore, 2017), e-health (Holden et al, 2017;Wöckl et al, 2012), marketing/advertising , cybersecurity (Dupree et al, 2016;Kim et al, 2019), video games (Ishii et al, 2018;Tychsen & Canossa, 2008), online news Watanabe et al, 2017), recommender systems (Hou et al, 2020;Konstantakis et al, 2020), and so on. In the era of personified big data (Spiliotopoulos et al, 2020), personas are particularly useful for segmenting diverse online user populations .…”
