How Argumentation can Enhance Dialogues in Social Networks

Many websites nowadays allow social networking between their users in an explicit or implicit way. In this work, we show how the theory of argumentation schemes can provide a valuable help to formalize and structure on-line discussions and user opinions in decision support and business oriented websites that hold social networks among their users. Two real case studies are considered and analysed. Then, guidelines for website and system design are provided to enhance social decision support and recommendations with argumentation.
