Argumentation is important for agent negotiation. In this paper, we develop an efficient framework for multi-agent argumentation. We identify aspects of classical argumentation theory that are suitable and useful for artificial agents and develop an argumentation framework around them. In the framework, we distinguish cooperation and argumentation and introduce skeptical and credulous agents. W...

This paper aims at giving a classification of argumentation games agents play within a multi-agent setting. We investigate different scenarios of such argumentation games that differ in the protocol used for argumentation, i. e. direct, synchronous, and dialectical argumentation protocols, the awareness that agents have on other agents beliefs, and different settings for the preferences of agen...

Argumentation mining research should address the challenge of recognition of argumentation schemes in formal text genres such as scientific articles. This paper argues that identification of argumentation schemes differs from identification of other aspects of discourse such as argumentative zones and coherence relations. Argumentation schemes can be defined at a level of abstraction applicable...

This paper discusses a process of argumentation. We propose an algorithm for dynamic treatment of argumentation in which all lines of argumentation are executed in succession, and the agent’s knowledge base can change during argumentation. We show that there exists a case in which an agent dynamically loses argumentation that would be considered won by a static analysis. We also show that the a...

This paper deals with strategical issues of arguing agents in a multi-agent setting. We investigate different scenarios of such argumentation games that differ in the protocol used for argumentation, i. e. direct, synchronous, and dialectical argumentation protocols, the awareness that agents have on other agents beliefs, and different settings for the preferences of agents. We give a thorough ...

In this paper, we introduce the methodology and techniques of metaargumentation to model argumentation. The methodology of meta-argumentation instantiates Dung’s abstract argumentation theory with an extended argumentation theory, and is thus based on a combination of the methodology of instantiating abstract arguments, and the methodology of extending Dung’s basic argumentation frameworks with...

This article1 proposes a complete framework for handling the dynamics of an abstract argumentation system. This frame can encompass several belief bases under the form of several argumentation systems, more precisely it is possible to express and study how an agent who has her own argumentation system can interact on a target argumentation system (that may represent a state of knowledge at a gi...
