Annotation of Emotions in Real-Life Video Interviews: Variability between Coders

AbstractResearch on emotional real-life data has to tackle the problem of their annotation. The annotation of emotional corpora raises the issue of how different coders perceive the same multimodal emotional behaviour. The long-term goal of this paper is to produce a guideline for the selection of annotators. The LIMSI team is working towards the definition of a coding scheme integrating emotion, context and multimodal annotations. We present the current defined coding scheme for emotion annotation, and the use of soft vectors for representing a mixture of emotions. This paper describes a perceptive test of emotion annotations and the results obtained with 40 different coders on a subset of complex real-life emotional segments selected from the EmoTV Corpus collected at LIMSI. The results of this first study validate previous annotations of emotion mixtures and highlight the difference of annotation between male and female coders.
