  This study analyzes the possible relationship between personality traits, in
terms of Big Five (extraversion, agreeableness, responsibility, emotional
stability and openness to experience), and social interactions mediated by
digital platforms in different socioeconomic and cultural contexts. We
considered data from a questionnaire and the experience of using a chatbot, as
a mean of requesting and offering help, with students from 4 universities:
University of Trento (Italy), the National University of Mongolia, the School
of Economics of London (United Kingdom) and the Universidad Cat\'olica Nuestra
Se\~nora de la Asunci\'on (Paraguay). The main findings confirm that
personality traits may influence social interactions and active participation
in groups. Therefore, they should be taken into account to enrich the
recommendation of matching algorithms between people who ask for help and
people who could respond not only on the basis of their knowledge and skills.
