Journal of Logic and Computation (JLC): Special Issue on Loops in Argumentation

posted Nov 27, 2012, 4:21 AM by Amministratore Sito Web

Arguments can be linked together by various kinds of relationships (e.g attack, defense, derivation, support, ...) 
lending themselves to direct representation as graph- or network-based formalisms. 
Dung's argumentation framework, encompassing a binary attack relation between arguments, 
is probably the most known one, but other kinds of argumentation networks have also been proposed in the literature. 
Whatever relationship between arguments is considered, a circularity in it poses questions which are both conceptual and practical. 
On the conceptual side, one has to make sense, if possible, of the loop situation, i.e. either to give it an interpretation or reject it 
(e.g. What does a circular support relation mean? Does it represent a valid support in some sense? 
or, for the attack relation, have odd- and even-length attack loops the same or a different nature?). 
On the practical side, one needs to take into account the presence of loops in defining models and algorithms 
operating on argumentation networks, primarily when it comes to assess the justification status of arguments.

This kind of loop-related questions are receiving increasing attention in the literature 
(again, especially for attack loops in the context of Dung's framework) but a wealth of further developments is sought: 
the aim of this special issue is to collect together high-level works assessing and/or advancing the state of the art 
in dealing with (various kinds of) loops in (various kinds of) argumentation networks and argumentation-related areas.
We solicit original submissions on topics including, but not limited to:
- causes, nature and conceptual status of circular relationships in formal and informal argumentation
- handling of loops in argumentation networks at semantic and/or algorithmic level
- loops in argumentation networks vs. loops in logic programming, dialogue protocols and other argumentation-related formalisms
- loops in actual argumentation-based reasoning and dialogues (legal reasoning, evidence-based reasoning, decision support, negotiation, deliberation, ...)

We encourage submissions of high quality, original papers which are not simultaneously submitted for publication elsewhere.
Reviewing will take place according to the standards common at JLC. 
Authors will be able to keep part of the copyright, so that their work can also be published by other means 
(for instance as book chapters), after the special issue has appeared.
