CyberEmotions: the good, the bad, the neutral - effect of an affective profile in dialog system-user online conversations

Marcin Skowron, Stefan Rank

Emotionally driven online behavior is traceable in a wide range of human communication processes on the Internet. Here the sum of individual emotions of a large number of users, with their interconnectivity and complex dynamics influence formation, evolution and breaking-up of online communities. Our research concentrates on the basic communication process between two conversants. Such interactions constitute a fundament for the modeling of more complex, multi-agents communication processes. Using artificial conversational entities (dialog systems), we investigate the role of emotions in online, natural language based communication. Our previous work demonstrated that a dialog system's capability to establish an emotional connection, and further to conduct a realistic and enjoyable dialog was in pair with the results obtained in a Wizard of Oz setting. In this talk, we present findings from recent experiments on the effect of conversant affective profiles (i.e., positive, negative, neutral) and their influence on the communication processes. The results demonstrate that the affective profile to a large extent determines the assessment of users' emotional connection and enjoyment from the interaction while it does not significantly influence the perception of core capabilities of the dialog systems, i.e. dialog coherence, dialog realisticness. The emotional changes experienced by the participants during the online interactions were correlated with the type of artificial systems affective profile and induced changes to various aspects of the conducted dialogs, e.g., timing, communication style, users' expressions of affective states.
