Abstract

In Probabilistic Abstract Argumentation, arguments and attacks (nodes and edges) in a graph instance are associated with a probability value. These probabilities can be interpreted in different ways: for instance, in the constellation approaches, the probabilities introduce uncertainty in the topology of the graph. In this paper we use MetaProbLog, a ProbLog framework where facts in a logic program are annotated by probabilities; the purpose is to compute the probability of possible worlds of arguments. The tool is integrated in the web interface of ConArg, a constraint-programming based tool aimed to solve different problems in Abstract Argumentation.
