Agreement Technologies refer to computer systems in which autonomous software agents negotiate with one another, typically on behalf of humans, in order to come to mutually acceptable agreements. An agent may choose whether to fulfil an agreement or not, and it should fulfil it when there is an obligation to do so derived from the standing agreements. Autonomy, interaction, mobility and openness are key concepts studied within Agreement Technologies approach. Semantic alignment, negotiation, argumentation, virtual organisations, trust and reputation and several other technologies are part of the sandbox to define, specify and verify such systems.
