CONF Hung_ACMMM2010_2010/IDIAP The Wolf Corpus: Exploring group behaviour in a competitive role-playing game Hung, Hayley Chittaranjan, Gokul corpus deception human behaviour multi-party EXTERNAL http://publications.idiap.ch/attachments/papers/2010/Hung_ACMMM2010_2010.pdf PUBLIC ACM Multimedia 2010 October 2010 In this paper we present the Idiap Wolf Database. This is a audio-visual corpus containing natural conversational data of volunteers who took part in a competitive role-playing game. Four groups of 8-12 people were recorded. In total, just over 7 hours of interactive conversational data was col- lected. The data has been annotated in terms of the roles and outcomes of the game. There are 371 examples of dif- ferent roles played over 50 games. Recordings were made with headset microphones, an 8-microphone array, and 3 video cameras and are fully synchronised. The novelty of this data is that some players have deceptive roles and the participants do not know what roles other people play.
