Polyphonic Inter-Animation of Voices in Chats

This paper presents and discusses the idea that one reason for the success of collaborative problem solving is the polyphonic character of work in small groups. Polyphony, a concept taken from music, may occur in chats for problem solving, transforming dialog into a “thinking device”: Different voices jointly construct a melody (story, or solution) and other voices adopt differential positions, identifying dissonances (unsound, rickety stories or solutions). This polyphonic interplay may eventually make clear the correct (“sound”) construction. The paper also proposes software tools for identification and visualization of voices in chats.
