Argumentation-based　approach　to　negotiation,　which　allows　agents　to　exchange　additional　information　or　argue　their　beliefs　and　other　mental　attitudes　during　the　negotiation　process,　is　gaining　increasing　popularity　for　its　potential　ability　to　overcome　the　limitations　of　conventional　approaches.　Most　existing　argumentation-based　negotiation　mechanisms　are　logic　or　rule-based　and　provide　a　formal　or　conceptual　framework,　it＇s　somehow　far　from　real-life　application.　In　this　paper,　we　provide　an　applicable　system　framework　oriented　to　E-commerce　and　discuss　the　decision　architecture　of　arguing　agent.　It　is　a　foundation　for　developing　a　real-life　argumentation-based　negotiation　system　in　the　future.　©2010　IEEE.
