Defeasible argumentation has experienced a considerable growth in AI in the last decade. Theoretical results have been combined with development of practical applications in AI & Law, CaseBased Reasoning and various knowledge-based systems. However, the dialectical process associated with inference is computationally expensive. This paper focuses on speeding up this inference process by pruning...

Simply put, a multiagent system can be seen as a collection of autonomous agents that as a whole are able to accomplish goals beyond the reach of any of its members. Agent interaction is widely acknowledged as the feature that provides this added potential. Since many, if not all, of the attractive agent interactions can be recasted as deliberations, a formalization for this process is being ac...

Among the most general structures extending the framework by Dung are the abstract dialectical frameworks (ADFs). They come equipped with various types of semantics, with the most prominent – the labeling–based one – analyzed in the context of computational complexity, signatures, instantiations and software support. This makes the abstract dialectical frameworks valuable tools for argumentatio...

The tool of analysis is for us a further development of the historical materialist method, the dialectical method. We will not even waste our time debating the values of Marxism with those who are essentially hung up on white people – hung up to the point of ideological blindness. We understand the process of revolution, and fundamental to this understanding is this fact: Marxism is developed t...

This essay aims to demonstrate the theoretical purchase offered by linking Dewey’s educational theory with a rigorous account of dialectical development. Drawing on recent literature which emphasizes the continuing influence of Hegel on Dewey’s thought throughout the latter’s career, this essay reconstructs Dewey’s argument regarding the detrimental effects of “external aims” (e.g., grades, sta...

Defeasible argumentation is one of the approaches that attempt to address the challenges arising when we reason defeasibly, with several formalisms in the literature reaching a mature state. Nowadays, several of them started shifting their semantics towards a dialectical characterization. Therefore, we believe that a sufficiently generic model of the process of dialectical reasoning could also ...
