Center node: "an approach to characterize graded entailment of arguments through a label based framework"
  Abstract: Argumentation theory is a powerful paradigm that formalizes a type of commonsense reasoning that aims to simulate the human ability to resolve a specific problem in an intelligent manner. A classical argumentation process takes into account only the properties related to the intrinsic logical soundness of an argument in order to determine its acceptability status. However, these properties are not always the only ones that matter to establish the argument's acceptabilitythere exist other qualities, such as strength, weight, social votes, trust degree, relevance level, and certainty degree, among others.In this work, we redefine the argumentative process to improve the analysis of arguments by considering their special features in order to obtain more refined results. Towards this end, we propose adding meta-level information to the arguments in the form of labels representing quantifiable data ranking over a range of fuzzy valuations. These labels are propagated through an argumentative graph according to the relations of support, conflict, and aggregation between arguments. Through this process we obtain final labels that are useful in determining argument acceptability. We redefine the argumentative process improving the argumentation analysis considering special features of the arguments.We add meta-level information to arguments as labels representing quantifiable data ranking over a fuzzy valuations range.Labels are propagated through an argumentative graph according to the relations of support, conflict, and aggregation.Label information is used to establish the arguments' acceptability according to different acceptance levels.We define an acceptability threshold to determine whether an argument satisfies certain conditions to be accepted.
