Here we introduce an argumentation framework to structure argumentative debates. Our framework represents the arguments issued by the participants involved in a debate, the (attack and defence) relationships between them, as well as participants{\textquoteright} opinions on them. Furthermore, we tackle the problem of computing a collective decision from participants{\textquoteright} opinions. With this aim, we design an aggregation function that satisfies valuable social-choice properties. }, keywords = {Agreement Technologies, Argumentation, Social choice}, author = {Jordi Ganzer-Ripoll and Maite L{\'o}pez-S{\'a}nchez and Juan A.
