Artificial Intelligence (AIJ) . 195(0), 361 - 397, 2013.
This online version of the paper corrects an error in the version of the paper that appears in the AIJ (An explanation of the correction can be found here:
Corrigendum for: A General Account of Argumentation with Preferences). The online version here includes a modified version of Section 5.1 (and proofs of results in this section in the Appendix).
We are very grateful to Sjur Dyrkolbotn for drawing our attention to a problem with the definition of `reasonable inducing' that has now been corrected in this online version. Note that the counter-example to rationality noted in: P. M. Dung. An Axiomatic Analysis of Structured Argumentation for Prioritised Default Reasoning. ECAI2014, 267-272, 2014, is now no longer a counter-example according to this online version.
