Weakly Complete Semantics Based on Undecidedness Blocking [article]

Pierpaolo Dondio, Luca Longo
2021 arXiv   pre-print
Since the two families of semantics do not coincide, a principle-based analysis of the two approaches is provided.  ...  The analysis shows how our semantics satisfy a number of principles satisfied by Dung's complete semantics but not by Baumann et al. semantics, including directionality, abstention, SCC-decomposability  ...  We perform a principle-based analysis of such new semantics and a comparison with the weakly admissible semantics recently proposed by Baumann et al. [3] .  ...

The theorems of this paper assume that B is weakly admissible, i.e. olcf(B)<olp(B). (Every admissible ordinal is weakly admissible.) Under this assumption, S.  ...  Below 0'/*, there is a class of B-r.e. degrees called the tame degrees, whose structural analysis resembles that of the a-r.e. degrees for a admissible.  ... 

Beyond admissibility: accepting cycles in argumentation with game protocols for cogency criteria

Gustavo A. Bodanza, Fernando A. Tohmé, Guillermo R. Simari
2014 Journal of Logic and Computation  
In this paper we extend Dung's formal approach from admissibility to less demanding extension semantics allowing arguments in cycles of attacks.  ...  Furthermore, an algorithmic characterization of those games exhibits clearly how self-attacking or in odd-length cycles of attack can be rationally managed beyond the limits of admissibility.  ...  Baroni and Giacomin [3] presented a more systematic approach to the evaluation of extension semantics, based on how they satisfy certain principles.  ...

On the Acceptability of Meta-arguments

Guido Boella, Leendert van der Torre, Serena Villata
2009 2009 IEEE/WIC/ACM International Joint Conference on Web Intelligence and Intelligent Agent Technology  
Metaarguments are generated from atomic arguments, and extensions of acceptable meta-arguments are based on Dung's argumentation semantics.  ...  In this paper we introduce a theory of meta-argumentation, by using Dung's theory of abstract argumentation to reason about itself.  ...  Baroni and Giacomin identify two fundamental principles underlying the definition of extension-based semantics in Dung's framework, the language independent principle and the conflict free principle.  ...

A choice-semantical approach to theoretical truth

Holger Andreas, Georg Schiemer
2016 Studies in History and Philosophy of Science Part A  
A central topic in the logic of science concerns the proper semantic analysis of theoretical sentences, that is sentences containing theoretical terms.  ...  In this paper, we present a novel choice-semantical account of theoretical truth based on the epsilonterm definition of theoretical terms.  ...  The first one is to provide an explicit model-theoretic analysis of the epsilon account of theoretical terms based on a choicefunctional semantics for the epsilon operator ( [21, 4, 24] ).  ...

The Prospects of a Paraconsistent Response to Vagueness [chapter]

Dominic Hyde
2010 Cuts and Clouds  
Some have thought so but the majority view has been that a paracomplete response 1 -roughly, a truth-value gap response -is as radical a departure from classical semantics as is necessary (and, of course  ...  A paraconsistent response will require the abandonment of classical logic and requires a more radical departure from classical semantics. The choice is seen by many then to be clear.  ...  However, since it is traditionally a development of a non-classical semantics from a classical base, and this tradition has circumscribed the ensuing issues, problems and debate, supervaluationism as it  ...

Abstract argumentation and the rational man

States of Affairs as Structured Extensions in Free Logic

Hans-Peter Leeb
2020 Logic and Logical Philosophy  
By means of this principle, a strict criterion for the admissibility of objects as extensions of sentences can be derived: every object is admissible as the extension of a sentence that is preserved under  ...  The search for the extensions of sentences can be guided by Frege's "principle of compositionality of extension", according to which the extension of a composed expression depends only on its logical form  ...  I am indebted to Karel (Joe) Lambert for the discussion on a longer version of the paper as well as to an anonymous referee for his helpful comments.  ...

On the Intertranslatability of Argumentation Semantics

W. Dvořák, S. Woltran
2011 The Journal of Artificial Intelligence Research  
We provide such an investigation in terms of different semantics proposed for abstract argumentation frameworks, a nonmonotonic yet simple formalism which received increasing interest within the last decade  ...  Although the properties of these different semantics are nowadays well understood, there are no explicit results about intertranslatability.  ...  A preliminary version of this paper has been presented at the International Conference "30 Years of Nonmonotonic Logic".  ...

Declassification: Dimensions and principles

Andrei Sabelfeld, David Sands, J.D. Guttman
2009 Journal of Computer Security  
With a general declassification framework as a long-term goal, we identify some prudent principles of declassification.  ...  While the security community has recognised the importance of the problem, the state-of-the-art in information release is, unfortunately, a number of approaches with somewhat unconnected semantic goals  ...  The paper has also benefited from the comments of Gerard Boudol, Stephen Chong, Mads Dam, Roberto Giacobazzi, Sebastian Hunt, Peng Li, Isabella Mastroeni, David Naumann and the anonymous reviewers.  ...

Complexity-sensitive decision procedures for abstract argumentation

Wolfgang Dvořák, Matti Järvisalo, Johannes Peter Wallner, Stefan Woltran
2014 Artificial Intelligence  
In this work, we present a generic approach for reasoning over AFs, based on the novel concept of complexity-sensitivity.  ...  So far, implemented systems for evaluating AFs have either followed a straight-forward reduction-based approach or been limited to certain tractable classes of AFs.  ...  Our complexity analysis is based on six different classes of argumentation frameworks which are known to yield milder complexity results for at least one of these semantics.  ...

Offline and online data: on upgrading functional information to knowledge

Giuseppe Primiero
2012 Philosophical Studies  
The formal framework, on which the definitions are based, uses a contextual version of the verificationist principle of truth in order to connect functional to semantic information, avoiding Gettierization  ...  Its use in the formal epistemology of information theories is crucial to solve the debate on the veridical nature of information, and it represents the companion notion to standard strongly semantic information  ...  Acknowledgments This paper was first presented at an informal meeting of the IEG held at the Oxford e-Research Centre, June, 08, 2010.  ...
