GRADUAL SEMANTICS FOR WEIGHTED ARGUMENTATION GRAPHS
Argumentation is a reasoning approach based on the justification of claims by arguments. It has been used for solving different Artificial Intelligence problems, including decision making, reasoning with defeasible information and classification. An argumentation framework is a directed graph, in which the nodes represent arguments, and the edges represent attacks between pairs of arguments. Gradual semantics are methods of evaluating arguments in graphs, that assign to each argument a numerical value, representing its strength. They are usually defined by a set of equations relating the strengths of arguments. Those equations impose that the strength of an argument A is calculated by composing two functions: the first aggregates the strengths of all direct attackers of the argument A, calculating the overall strength of attacks toward A, and the other for computing the effect of the overall attack on the strength of A. The main problem in this approach is whether those equations define a unique gradual semantics, i.e., if the set of equations has an unique solution. In this talk, I will present different approaches for defining gradual semantics from the literature, and investigate if those approaches uniquely characterize a semantics. Then I will propose a set of properties for the aggregation and effect functions, which ensures the uniqueness of the corresponding semantics. I will also analyze the properties against the set of postulates for gradual semantics proposed in the literature.
