In this paper, the influence of intonation to recognize dialogue acts from speech is assessed. Assessment is based on an empirical approach: manually tagged data from a spoken-dialogue and video corpus are used in a CART-style machine learning algorithm to produce a predictive model. Our approach involves two general stages: the tagging task, and the(More)
In this paper a theory of dialogue acts analysis in problem-solving tasks-oriented conversations is presented. The theory postulates that in practical dialogues every transaction has a component in the obligations and the common ground planes of expression, and contributions made by dialogue acts making a " charge " in the transaction should be " balanced "(More)
In this paper a theory of dialogue structure of task oriented conversations and its associated tagging scheme are presented. The theory introduces two linguistic structures supporting the dialogue that, following traditional terminology, we call the obligations and common ground. The theory is illustrated with the detailed analysis of a transaction. We also(More)
