Aggregation operators to compute norm support in virtual communities

Resum Moderation in virtual communities should not be a private privilege. This paper proposes a method for participants in a social network to decide their own rules for accepting (or not) contents. With the norm argument map, participants are able to argue about norms and voice their opinions about other people?s arguments. This structure, equipped with a method to fuse all the data introduced by participants, makes it possible to evaluate the people?s support for a norm and decide whether the norm should be applied or discarded.
