We invite you to submit papers reflecting both finished works as well as works in progress, containing original and promising ideas. We welcome the following types of submissions:

  • Abstract (1-2 pages)
  • Short papers (2-4 pages)
  • Long papers (8-10 pages)

Long submitted papers will be peer-reviewed based on technical quality, relation to the topics of the conference, originality, relevance, significance, and clarity. Short papers will be evaluated for their significance considering them as ongoing work descriptions. Abstracts should reflect initial positioning and/or breaking ideas that provoke discussion. Note that all submissions must be original. Short and abstract accepted papers will be presented in lightning and poster sessions

Paper submissions must meet the following guidelines:



Accepted long and short papers are published at the conference proceedings book in the collection “Frontiers in Artificial Intelligence and Applications” of IOS Press.

The open-access proceedings are now available here.

We invite the authors of the best conference papers to submit extended versions of their work to the following Special Issues of indexed journals:

  1. The International Journal of Computational Intelligence Systems (Springer) is now welcoming submissions for a special issue titled “Advancing the Common Good: Special Issue on Applied AI Solutions.” This journal has a 2-year impact factor of 2.9.
  2. The Cognitive Systems Research journal (Elsevier) invites submissions for a special issue named “AI Cognitive Systems Applied to Social Scientific Research.” This journal has a 2-year impact factor of 3.9


After receiving the notification of acceptance, ACIA member students who will attend the conference can apply for grants funded by Associació Catalana d’Intel·ligència Artificial.
