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.

​The International Conference Series on Agreement Technologies is an interdisciplinary forum that brings together researchers and practitioners working on the various topics comprising this emergent and vibrant field. It provides an avenue to discuss and exchange new ideas and techniques for the design, implementation and verification of next generation open distributed systems centred on the notion of agreement among computational agents.



AT 2020 follows the successful outcome of the previous editions of the International Conference Series on Agreement Technologies: AT 2012 in Dubrovnik, Croatia, AT 2013 in Beijing, China, AT 2015 in Athens, Greece,  AT 2016 in Valencia, Spain, AT 2017 in Évry, France, and AT 2018 in Bergen, Norway.


AT 2020 will be held over the internet September 14 & 15, 2020. Initially, it was planned to be held on 13 and 14 July 2020 in Thessaloniki, Greece, be co-located with EUMAS 2020. Due to COVID-19 the conference was postponed twice and it was finally decided to become a virtual conference for 2020.
