Title: Discovering complex individual and social behavior patterns via Social network Analysis
Thanks to the availability of user profiles and records of activity, online social network analysis is relevant to discover complex individual and social behavior patterns.
The emergence of trust between users of online services is one of the most important phenomena, but it’s also hard to detect in records of users’ interactions, and even harder to replicate by abstract, generative models.
Seminario 1: February 6, 2019 at 11:00
In this seminar we report our results on the emergence of “trusted” users (over time) by studying the evolution of topological and centrality measures in the network mapping trust relations among members of an Online Social Network.
Seminario 2: February 6, 2019 at 14:30
This seminar illustrates how social network analysis tools can be used to discover reputable users in online communities: given a “who-trusts-whom” network in which users can create trust relationships as well as review items and evaluate posted reviews, we investigate whether the most central actors in the network are also highly reputable, i.e., if they are likely to provide helpful reviews to the benefit of all community members.
