We propose an approach to reasoning about conversation protocols within the framework of a logic-based agent language. We show how to embed a theory of communicative actions in the framework of a modal logic of action and beliefs, to specify software agents that, situated in a multi-agent environment, can interact with one another by a speech act based communication mechanism. Agents have their...

The interface for the next generation of Unmanned Vehicle Systems should be an interface with multi-modal displays and input controls. Then, the role of the interface will not be restricted to be a support of the interactions between the ground operator and vehicles. Interface must take part in the interaction management too. In this paper, we show that recent works in pragmatics and philosophy...

Zipf's law seems to be ubiquitous in human languages and appears to be a universal property of complex communicating systems. Following the early proposal made by Zipf concerning the presence of a tension between the efforts of speaker and hearer in a communication system, we introduce evolution by means of a variational approach to the problem based on Kullback's Minimum Discrimination of Info...

A number of researchers have investigated the use of planbased approaches to generate textual explanations (e.g., Appelt 1985; Hovy 1988; Moore 1989; Maybury 1990b). This paper extends this approach to generate multimedia explanations by defining three types of communicative acts: linguistic acts (illocutionary and locutionary speech acts), visual acts (e.g., deictic acts), and mediaindependent...

According to European standards, the promotion of learning more than one foreign language implies a comprehensive reform policies with new objectives, approaches activities and accessible digital teaching/learning platforms. Throughout history, has experienced changes in its evolution from traditional into attractive, creative effective communicative approach-method. Relying on idea that learne...

Recent communicative approaches have suggested that one goal of English language teaching should be to replicate 'genuine' or 'natural' rather than 'typical' or 'traditional' classroom communication. This article argues that such a goal is both paradoxical and unattainable, and that there are serious flaws in the assumptions underlying the communicative orthodoxy concerning ELT classroom intera...

We aim to define conversational agents exhibiting distinctive behavior. To this aim we provide a small set of parameters to allow one to define behavior profiles and then leave to the system the task of animating the agents. Our approach is to manipulate the behavior tendency of the agents depending on their communicative intention and emotional state. In this paper we define the concepts of Ba...

In this paper, we present an approach to treat and model the processing (i.e. recognition and production) of communicative gestures as grounded motor cognition. We first review cognitive theories and neuropsychological studies on human motor cognition. On this basis, we propose a computational framework that connects the sensorimotor processing of hand gestures in representational structures of...
