Argumentation as information input

Given a network (S,R) , with R ⊆ S2, we view the nodes of S as containing information and view xRy as x transmitting information to y. We argue that such networks provide a more general account of attack and defense and general arguments exchange on issues between participants in Facebook and Twitter, as well as being able to simulate the traditional Dung approach. We define a general semantics for such networks.
