We understand a service engagement as a form of collaboration arising in a sociotechnical system (STS). Although STSs are fruitfully modeled using normative abstractions such as commitments, a conventional (practical) commitment can capture only part of the story, namely, a debtor’s promise to the creditor to bring about the consequent if the antecedent holds. In contrast, in a dialectical comm...

In this paper we answer empirically the following research question: “Are dialectical explanation methods more effective than one-shot explanation methods for Intersection of Closed Repairs inconsistency tolerant semantics in existential rules knowledge bases?” We ran two experiments with 84 and respectively 38 participants and showed that under certain conditions dialectical approaches are sig...

Defeasible argumentation is one of the approaches that addresses the challenges arising when we reason defeasibly, with several formalisms in the literature reaching a mature state. Considering that most of these theories eventually shifted their semantics towards dialectical characterizations, we believe that a sufficiently generic model of the process of reasoning in dialectical terms could a...

We propose a dialogue game for mediation and its formalization in DGDL. This dialectical system is available as software through Arvina for automatic execution. This work expands the literature in dialectical systems, in particular those for more than two players, and shows the practical impact on mediation activity through the opportunity offered to mediators once implemented.

Dialectical Frameworks

The study of fallacies is at the heart of argumentation studies. In response to Hamblin’s devastating critique of the state of the theory of fallacies in 1970, both formal dialectical and informal approaches to fallacies developed. In the current paper, we focus on an influential informal approach to fallacies, part of the pragma-dialectical theory of argumentation. Central to the pragma-dialec...
