Inferring Acceptance and Rejection in Dialogue by Default Rules of Inference

This paper discusses the processes by which conversants in a dialogue can infer whether their assertions and proposals have been accepted or rejected by their conversational partners. It expands on previous work by showing that logical consistency is a necessary indicator of acceptance, but that it is not sufficient, and that logical inconsistency is sufficient as an indicator of rejection, but it is not necessary. I show how conversants can use information structure and prosody as well as logical reasoning in distinguishing between acceptances and logically consistent rejections, and relate this work to previous work on implicature and default reasoning by introducing three new classes of rejection: {\sc implicature rejections}, {\sc epistemic rejections} and {\sc deliberation rejections}. I show how these rejections are inferred as a result of default inferences, which, by other analyses, would have been blocked by the context. In order to account for these facts, I propose a model of the common ground that allows these default inferences to go through, and show how the model, originally proposed to account for the various forms of acceptance, can also model all types of rejection.Comment: 37 pages, uses fullpage, lingmacros, name

Advancing dialogue in service-dominant logic: Collective reframing supported by framed arrangement

While dialogue is considered an ideal interaction in value co-creation theories, extant studies have not looked at how it is realized in the value co-creation process. Therefore, this paper empirically studies better ways to realize dialogue based on a framework connecting service-dominant logic and two key concepts of actor-network theory: "performativity" and "arrangement." We confirm a process under which a statement that declares the existence of dialogue reshapes business arrangements. Finally, an arrangement strongly framed by the statement better contributes to the actualization of dialogue, that is, collective reframing. We imply that if business people want to enhance the possibility of actualizing dialogue, the framing of business arrangements by investment and selection is needed. Finally, we indicate the contradictions contained within the business dialogue, as revealed in the empirical analysis and interpretation based on our framework

A Review of Verbal and Non-Verbal Human-Robot Interactive Communication

In this paper, an overview of human-robot interactive communication is presented, covering verbal as well as non-verbal aspects of human-robot interaction. Following a historical introduction, and motivation towards fluid human-robot communication, ten desiderata are proposed, which provide an organizational axis both of recent as well as of future research on human-robot communication. Then, the ten desiderata are examined in detail, culminating to a unifying discussion, and a forward-looking conclusion

The agreement process: an empirical investigation of human-human computer-mediated collaborative dialogs

this paper, we investigate the empirical correlates of the agreement process. Informally, the agreement process is the dialogue process by which collaborators achieve joint commitment on a joint action. We propose a specific instantiation of the agreement process, derived from our theoretical model, that integrates the IRMA framework for rational problem solving (Bratman, Israel, and Pollack 1988) with Clark's work (1992; 1996) on language as a collaborative activity; and from the characteristics of our task, a simple design problem (furnishing a two room apartment) in which knowledge is equally distributed among agents, and needs to be shared. The main contribution of our paper is an empirical study of some of the components of the agreement process. We first discuss why we believe the findings from our corpus of computer-mediated dialogues are applicable to human-human collaborative dialogues in general. We then present our theoretical model, and apply it to make predictions about the components of the agreement process. We focus on how information is exchanged in order to arrive at a proposal, and on what constitutes a proposal and its acceptance / rejection. Our corpus study makes use of features of both the dialogue and the domain reasoning situation, and led us to discover that the notion of commitment is more useful to model the agreement process than that of acceptance / rejection, as it more closely relates to the unfolding of negotiation

On the nature and role of intersubjectivity in communication

We outline a theory of human agency and communication and discuss the role that the capability to share (that is, intersubjectivity) plays in it. All the notions discussed are cast in a mentalistic and radically constructivist framework. We also introduce and discuss the relevant literature
