Abstract dialectical frameworks (ADFs) have been introduced as a formalism for modeling argumentation allowing general logical satisfaction conditions and the relevant argument evaluation. Different criteria used to settle acceptance of arguments are called semantics. Semantics ADFs so far mainly defined based on concept admissibility. However, notion strongly admissible semantics studied abstr...

On one hand, it considers history of development realism as philosophical positions embedded in evolution European tradition. other changes Lectorsky’s are traced from dialectical materialism to post-Marxist variant latter is built basis analysis cognitive science recognition limitations so-called computationa...

How to model relevance in argumentation is an important problem for informal logic. Dialectical relcvance is determined by the use of an argument for some purpose in different types of dialogue, according to the ncw dialectic. A central type of dialogue is persuasion dialogue in which one participant uses rational argumentation to try to get the other participant to accept a designated proposit...

The authors propose the use of a dialectical argumentation formalism for chance discovery in domains where knowledge is distributed across a number of distinct knowledge-bases, as in a system of autonomous software agents. Each agent may have only a partial view of a problem, and may have insufficient knowledge to prove particular hypotheses; our formalism provides a means to aggregate across t...
