Claim 0:
1. A framework for identification of cyber-bullying on social media sites, comprising:
a model trained according to a representation learning framework configured to:
construct one or more multi-modal representations of one or more social media sessions; and

a learning network configured to:
estimate a likelihood of bullying associated with each of the one or more social media sessions using the one or more multi-modal representations; and
predicting a time interval between one or more comments of the one or more social media sessions;

wherein a graph reconstruction error determined by the representation learning framework, an energy estimation loss determined by the learning network, and a time interval prediction error determined by the learning network are used to determine a total loss associated with bullying identification; and
wherein the total loss associated with bullying identification is used to optimize the representation learning framework and the learning network,
wherein the model is configured for unsupervised cyberbullying detection and incorporates inter-arrival times of a social media session to leverage temporal dynamics associated with repeated acts of aggression over time.
