The AIMSA conferences have been held biannually in Bulgaria since 1984. Traditionally they are organized by an international Program Committee (normally more than 20 members and maximum 3-4 Bulgarians, working in the country) and are attended by 70 to 150 participants, coming from all over the world. The majority of AIMSA editions have been sponsored by ECCAI. The AIMSA proceedings have been published by North-Holland, World Scientific Publishing, IOS Press and Springer Verlag. The AIMSA series of conferences covers a wide range of AI topics. It is aimed at a wide audience of both AI practitioners and theorists. The conference has always responded to up-to-date issues and contemporary topics in AI. The hot topics of the conference include Knowledge Representation and Reasoning, Machine Learning, Natural Language Processing, Logic Programming, Semantic Web research and applications, etc.

The AIMSA conferences have been chaired by Wolfgang Bibel, Tim O'Shea, Philippe Jorrand, Ben du Boulay, Alan Ramzay, Fausto Giunchiglia, Stefano Cerri, Donia Scott, Dieter Fensel, Christoph Bussler, John Domingue, Jerome Euzenat, Paolo Traverso and Marco Pistore, Darina Dicheva, Allan Ramsay, Pascal Hitzler, Sergei O.

The quality of the papers and the good organization (done by Institute of Technical Cybernetics and Robotics - Bulgarian Academy of Sciences, its successor Institute of Information and Communication Technologies - BAS, and the Bulgarian AI Association) made the AIMSA conferences internationally known and often cited in the AI community.
