Preface
Agreement is one of the crucial social concepts that helps human agents to cope
with their social environment and is present in all human interactions. In fact,
without agreement there is no cooperation and ultimately social systems cannot
emerge. Agreement is necessary in our everyday life.
Until recently, the concept of agreement was a domain of study mainly for
philosophers, sociologists and was only applicable to human societies. However,
this situation has changed in the recent years, especially with the spectacular
emergence of information society technologies. Computer science has moved from
the paradigm of an isolated machine to the paradigm of a network of systems and
of distributed computing. Likewise, artificial intelligence is quickly moving from
the paradigm of an isolated and non‐situated intelligence to the paradigm of
situated, social and collective intelligence. Hence, the concept of agreement has
become key for a robust understanding and an efficient implementation of
artificial social systems.
In this context, Agreement Technologies is a new approach of Distributed Artificial
Intelligence for constructing large‐scale open distributed computer systems. This
workshop on Agreement Technologies is specifically addressed for any work that
aims at developing models, frameworks, methods and algorithms for constructing
such systems. In other words, this workshop focuses on approaches and solutions
for the needs of next generation computing systems where autonomy, interaction
and mobility will be the key issues. Most importantly, it concentrates on
techniques that enable software components to reach agreements on the mutual
performance of services.
Agreement Technologies integrates many research efforts from different fields of
Artificial Intelligence. Hence, this workshop is specifically tailored to research
works related to this new approach. As CAEPIA is the leading Artificial Intelligence
conference in Spain, it is a good forum to celebrate this workshop. Finally, the
editors would like to thank all the people that bring about WAT and CAEPIA 2009.
First of all, thanks to the authors for ensuring the richness of the workshop and the
members of the program committee for their professionalism and dedication.
Furthermore, we owe particular gratitude to the CAEPIA organizing committee.
