       abstract = {Dominance - a behavioral expression of power - is a fundamental mechanism of
social interaction, expressed and perceived in conversations through spoken words 
and audio-visual nonverbal cues.
The automatic modeling of dominance patterns
from sensor data represents a relevant problem in social computing.
In this paper, we present a systematic study on dominance modeling in
group meetings from fully automatic nonverbal activity cues, in a multi-camera, multi-microphone
setting. We investigate efficient audio and visual activity cues
for the characterization of dominant behavior, analyzing single and
joint modalities. Unsupervised and supervised approaches for dominance
modeling are also investigated. Activity cues and models are objectively evaluated
on a set of dominance-related classification tasks, derived from an analysis
of the variability of human judgment of perceived dominance in group discussions.
Our investigation highlights the power of relatively simple
yet efficient approaches 
and the challenges of audio-visual integration. This constitutes the most detailed study on automatic dominance modeling
in meetings to date.},
