Formalizing emotional e-commerce agents for a simple negotiation protocol

Electronic commerce has become a central pillar of the Internet. Easy access, mobile devices with permanent connection, social networks and the real-time conversation streams have a big influence over B2C and C2C commerce. Currently, e-commerce becomes a social commerce, much closer to the traditional paradigm. The inclusion of emotional components in the act of trading complies with the current social trends and further approaches the electronic commerce to the traditional one. This paper continues the work on an emotional e-commerce platform by formalizing the customer, supplier and community agents. We present a simple negotiation protocol as a proof of concept.
