Query: An Affective Situation Labeling System from Psychological Behaviors in
  Emotion Recognition   This paper presents a computational framework for providing affective labels
to real-life situations, called A-Situ. We first define an affective situation,
as a specific arrangement of affective entities relevant to emotion elicitation
in a situation. Then, the affective situation is represented as a set of labels
in the valence-arousal emotion space. Based on physiological behaviors in
response to a situation, the proposed framework quantifies the expected emotion
evoked by the interaction with a stimulus event. The accumulated result in a
spatiotemporal situation is represented as a polynomial curve called the
affective curve, which bridges the semantic gap between cognitive and affective
perception in real-world situations. We show the efficacy of the curve for
reliable emotion labeling in real-world experiments, respectively concerning 1)
a comparison between the results from our system and existing explicit
assessments for measuring emotion, 2) physiological distinctiveness in
emotional states, and 3) physiological characteristics correlated to continuous
labels. The efficiency of affective curves to discriminate emotional states is
evaluated through subject-dependent classification performance using
bicoherence features to represent discrete affective states in the
valence-arousal space. Furthermore, electroencephalography-based statistical
analysis revealed the physiological correlates of the affective curves.
