Popis: In abstract argumentation, multiple argumentation semantics for choosing sets of jointly acceptable arguments have been defined. In the principle-based approach, multiple principles have been proposed and formalized in order to guide the choice for a semantics and the search for new semantics. Admissibility is a central principle satisfied by many semantics, including complete, stable, grounded and preferred. A more recently introduced principle is the INRA principle, motivated by considerations about the relevance of arguments and supported by a cognitive study. This paper additionally introduces and motivates the SAFWOC principle in order to positively distinguish less abstention-friendly semantics like preferred and stable from more abstention-friendly semantics like grounded and complete. After observing that no existing semantics satisfies these three principles, we define the novel choice-preferred semantics that satisfies the three principles. Additionally we show that choice-preferred satisfies further desirable principles like existence, directionality, SCC-recursiveness and completeness.
