The Modulation of Cooperation and Emotion in Dialogue: The REC Corpus

In this paper we describe the Rovereto Emotive Corpus (REC) which we collected to investigate the relationship between emotion and cooperation in dialogue tasks. It is an area where still many unsolved questions are present. One of the main open issues is the annotation of the socalled “blended” emotions and their recognition. Usually, there is a low agreement among raters in annotating emotions and, surprisingly, emotion recognition is higher in a condition of modality deprivation (i. e. only acoustic or only visual modality vs. bimodal display of emotion). Because of these previous results, we collected a corpus in which “emotive” tokens are pointed out during the recordings by psychophysiological indexes (ElectroCardioGram, and Galvanic Skin Conductance). From the output values of these indexes a general recognition of each emotion arousal is allowed. After this selection we will annotate emotive interactions with our multimodal annotation scheme, performing a kappa statistic on annotation results to validate our coding scheme. In the near future, a logistic regression on annotated data will be performed to find out correlations between cooperation and negative emotions. A final step will be an fMRI experiment on emotion recognition of blended emotions from face displays.
