In dialogue a set of actions are realized by linguistic means, and have consequences on the state of the interaction between two speakers. Analysing the interaction, the emphasis can be put on the effects on the mental states of the participants or on the social effects of dialogue acts (obligations, commitments) resulting from conventions. We try here to relate a formal semantics approach to d...

This paper describes some of the basic cooperative mechanisms of dialogue. Ideal cooperation is seen as consisting of four features (cognitive consideration, joint purpose, ethical consideration and trust), which can also to some extent be seen as requirements building on each other. Weaker concepts such as &&coordination'' and &&collaboration'' have only some of these features or have them to ...

Formal argumentation-based dialogue systems have attracted considerable research interest in the past. Most research in this area introduce “dialectical wrappers” over argumentation formalisms to model verbal interactions amongst agents, resulting in different dialogue models for different types of dialogues, e.g. inquiry or persuasion. In this work, we take a different approach by deploying a ...

In this paper, we present a general framework and architecture for maintaining dialogue coordination in spoken dialogue systems, in which intended behaviors and goals are incrementally performed during the course of maintaining dialogue coordination. The dialogue structure emerges as a result from interaction between user and the dialogue system. The key feature of this design for the systems i...

In this paper I proposed the creation of a dialogue document for making available the knowledge contained within a creative conversation process. I discussed three main issues: the role of ordinary documents, the need to better represent conversation processes rationally, and the costs of editing conversation. I looked at the reasons why we rarely see the knowledge from the conversation process...

We explore the utility of a computational framework for social authority in dialogue, codified as utterance-level annotations. We first use these annotations at a macro level, compiling aggregate statistics and showing that the resulting features are predictive of group performance in a task-based dialogue. Then, at a micro level, we introduce the notion of an interaction pattern, a formulation...

In this paper we propose a new persuasion dialogue game for agent communication. We show how this dialogue game is modeled by a framework based on social commitments and arguments. Called Commitment and Argument Network (CAN), this framework allows us to model communication dynamics in terms of actions that agents apply to commitments and in terms of argumentation relations. This dialogue game ...

Decent work concept is based on four pillars namely employment, employment rights,social dialogue, social security. The uptake of decent work practices in smallholder dairy farms is poorly understood. This paper explores the linkage between socioeconomic status of smallholder farmer and compliance to decent work standards. The study involved 123 farmers. Three index scales were constructed to m...

This paper presents a dialogue system in the form of an ECA that acts as a sociable and emotionally intelligent companion for the user. The system dialogue is not task-driven but is social conversation in which the user talks about his/her day at the office. During conversations the system monitors the emotional state of the user and uses that information to inform its dialogue turns. The syste...
