*SocioDim*) [2] has been proposed for collective behavior
social dimensions can be categorized into node-view and
The framework

*SocioDim *is composed of two steps:
1) social dimension extraction, and 2) discriminative
learning. In the first step, latent social dimensions are
extracted based on network topology to capture the
potential affiliations of actors. These extracted social
dimensions represent how each actor is involved in diverse
affiliations. One example of the social dimension
representation is shown in Table 1. The entries in this table
denote the degree of one user involving in an affiliation.
These social dimensions can be treated as features of actors
for subsequent discriminative learning. Since a network is
converted into features, typical classifiers such as support
vector machine and logistic regression can be employed.
The discriminative learning procedure will determine
which social dimension correlates with the targeted
behaviour and then assign proper weights.
A key observation is that actors of the same
affiliation tend to connect with each other. For instance, it
is reasonable to expect people of the same department to
interact with each other more frequently. Hence, to infer
actors’ latent affiliations, we need to find out a group of
