Covering hidden groups is based on the observation that a pattern of communica-tions exhibited by actors in a social group pursuing a common objective is different from that of a randomly selected set of actors. We distinguish two types of hid-den groups: temporal, which exhibits repeated communication patterns; and spatial.

Temporal pattern analysis (t-patterns) can be used to isolate frequent recurrent patterns in routine tasks that appear repeatedly in the same temporal configuration. Using tf-idf statistics, each task can then be defined in terms of its temporal task footprint, a ranked list of temporal patterns along with their typical frequencies.
