....his her goal of performing a Communicative Act, that is of communicating something to a Hearer, we are proposing a method to compute the appropriate performative of the communicative act and the corresponding facial expressions. 2 Background According to a model in terms of goals and beliefs ([3], 5] a speech act, and we say any communicative act a smile, a gesture, a gaze may be decomposed into a set of cognitive units represented as logical propositions. Some of these cognitive units form the propositional content (what the Speaker is speaking of) others form the Speaker s ....

....eyebrow. Finally, the Graphics Output component generates an animation of a face that moves lips to say Here and at the same time performs the performative expression of suggesting. 5 System design The system is designed according to a cognitive model of social and communicative action ([3], 5] Information in the Hearer model and in the Inference Rules is represented in a propositional format that will be implemented in the Golem Inference Engine by [16] The facial model we will be using is a structurally defined 3D model [11] It uses FACS, a notational system developed by [6] ....

....as explained in the following section. 4 Coherence and misunderstandings We consider a new contribution coherent if a relation exists among the intentions underlying it and the previous pending intentions of the interactants, either expressed explicitly, or inferred by reasoning on their plans [9]. An utterance is coherent with the previous context if its receiver A can interpret it as a means of the speaker B to achieve a goal g such that: 1. Goal adherence: g is one of the goals previously expressed by A. 2. Goal adoption: g is one of the goals that B has inferred A is going to aim at; ....

....section describes a set of phenomena which are explained by the dialogue model we have adopted. 4 The coherence of an interaction In our work, we aimed at analyzing dialogue coherence on the basis of general principles, which can be exploited in order to model different phenomena uniformly. In Castelfranchi Parisi (1980) and Castelfranchi Falcone (1997) some principles were defined in order to model the acquisition of intentions among cooperating agents. We found that the cooperation notion introduced in those works was particularly useful for defining and modeling dialogue coherence in a framework of agent ....

.... have identified it because it was communicated explicitly by the partner (by means of an illocutionary act) or may have inferred it although it was not stated overtly (Allen Perrault 1980, Allen 1983) Following the notion of cooperation in terms of goal delegation and goal adoption defined in Castelfranchi Parisi (1980) and Castelfranchi Falcone (1997) we consider an utterance coherent with the previous context if its receiver A can interpret it as the means of the speaker B to achieve a goal g such that: 1. Goal adherence: g is a goal that A has expressed explicitly that he wants B to achieve; in other ....

....approach to dialogue interpretation makes it possible to adopt a flexible notion of coherence: a new contribution is considered coherent as long as a relation can be identified among the intentions underlying an action and the previous pending intentions of the interactants. Following the ideas of Castelfranchi Parisi (1980), we consider an utterance coherent with the previous context if and only if its receiver can interpret it as a means of the speaker to achieve an unsatisfied goal g which realizes one of the following coherence relations: 1. Goal adherence: g is one of the goals addressed explicitly by the ....

....un sistema intelligente capace di reagire all input tenendo conto non solo degli scopi espressi dall utente, ma anche dei propri obiettivi e delle proprie credenze. Un sistema cooperativo deve interpretare l input per identificare anche gli obiettivi dell utente non espressi esplicitamente [6]; se tali scopi sono soddisfacibili e non contrastano con gli obiettivi del sistema, questo li adottera , cooperando con l utente per realizzarli. Il riconoscimento di piani ha avuto un ruolo importante nello sviluppo di interfacce cooperative: storicamente, e stato introdotto per identificare i ....
