On the Social Influence in Human Behavior: Physical, Homophily, and Social Communities

Abstract: Understanding the forces governing human behavior and social dynamics is a challenging problem. Individuals' decisions and actions are affected by interlaced factors, such as physical location, homophily, and social ties. In this paper, we propose to examine the role that distinct communities, linked to these factors, play as sources of social influence. The ego network is typically used in the social influence analysis. Our hypothesis is that individuals are embedded in communities not only related to their d… Show more

“…Though the one-hop neighborhood (ego network) appeared as the straightforward solution to detect the set of input (nodes) that affected the prediction related to a given user, results show that the ego network alone is not enough to explain the social influence phenomenon. As we discussed in Luceri et al (2017), mesolevel structures, such as communities, provide a significant contribution to the understanding of this phenomenon. Results show that C-SIDL closely approaches the performance of the general model.…”

“…In the second direction, we will evaluate different solutions to group users in mesolevel structures and employ C-SIDL accordingly. A wide spectrum of possibilities can be explored for this purpose, ranging from homophily community (Luceri et al 2017), which groups together similar individuals with low social distance (Förster et al 2012), to tensor decomposition techniques (Kolda and Bader 2009), which extract sub-network modules composed of nodes with correlated activity.…”

“…The HBDC experiments aim to collect large-scale data of human beings with the objective of understanding and predicting the subjects' behavior and the social dynamics among them. The purpose is to investigate the forces that drive people aggregation in groups (or communities) [42] and to examine the factors that mostly affect individuals' decisions and actions.…”
