If the abnormality prediction and a smaller σ(t) score in sub-region l during time t exceeds a given threshold, the Event Signal Discovery component outputs a candidate event e(l, t) that stands for the set of all the Instagram and Twitter posts that are posted during time t and within location l. 2 Event Signal Classification Once Event Signal Discovery component produces a candidate event signal e(l, t), the Event Signal Classification component first extracts features from e(l, t) and classifies it as true or false by a supervised learning model.

On the other hand, finding a large H (which usually has a high w(H)) may not lead to an acceptable σ(H), either. Therefore, the key is to strike a good balance between the graph size |H| and the total weight w(H). 2) HMGF includes a hop constraint (say h = 2) on friend edges to ensure that every pair of individuals is not too distant socially from each other. , dE G (u, v) > h which is defined based on existing friend edges. In this case, it may not always be a good strategy to prioritize on large-weight edges in order to maximize σ(H), especially when u and v do not share a common friend nearby via the friend edges.

The social presence theory in social psychology suggests that computer-mediated online interactions are inferior to face-to-face, inperson interactions. In this paper, we consider the scenarios of organizing in person friend-making social activities via online social networks (OSNs) and formulate a new research problem, namely, Hop-bounded Maximum Group Friending (HMGF), by modeling both existing friendships and the likelihood of new friend making.
