Structural Models of Human Social Interactions in Online Smart Communities: the Case of Region-based Journalists on Twitter [article]

Mustafa Toprak, Chiara Boldrini, Andrea Passarella, Marco Conti
2021 arXiv   pre-print
In this work, we focus on the ego networks of journalists on Twitter, considering 17 different countries, and we investigate whether they feature the same characteristics observed for other relevant classes  ...  Their ego network structure is very aligned with reference models derived in anthropology and observed in general human ego networks.  ...  Thus, not only academic studies on human behavior in the offline world via OSN data but also the comparison between offline and online human behavior have gained popularity.  ...

Contextual Permission Models for Better Privacy Protection

Primal Wijesekera
2018 Zenodo  
These permission systems, however, lack the ability to understand users' privacy expectations leaving a significant gap between how permission models behave and how users would want the platform to protect  ...  We performed a 38-person field study to measure the efficiency and usability of the new permission model. Based on exit interviews and 5M data points [...]  ...  Once the model reaches adequate training, we can use model decision confidence to analyze how the ML model performs for different users and examine the tradeoff between user involvement and accuracy.  ...
