5th International Workshop on EXplainable and TRAnsparent AI and Multi-Agent Systems
(EXTRAAMAS)
in conjunction with AAMAS 2023, London, 29 May- 2 June, 2023



Running since 2019, EXTRAAMAS is a well-established workshop and forum on EXplainable and TRAnsparent AI and Multi-Agent Systems. It aims to discuss and disseminate research on explainable artificial intelligence, with a particular focus on intra/inter-agent explainability and cross-disciplinary perspectives. In its 5th edition, EXTRAAMAS identifies four particular focus topics with the ultimate goal of strengthening cutting-edge foundational and applied research. This of course comes in addition to the main theme of the workshop, focused as usual on XAI fundamentals. The four tracks for this year are:
- Track 1: XAI in symbolic and subsymbolic AI: the “AI dichotomy” separating symbolic AKA classical AI from connectionism AI has been persistent for more than seven decades. Nevertheless, the advent of explainable AI has accelerated and intensified the efforts to bridge this gap, since providing faithful explanations of black-box machine learning techniques would necessarily mean combining symbolic and subsymbolic AI. This track aims at discussing the recent works on this hot topic of AI.
-- Track chair: Giovanni Ciatto, University of Bologna, Italy.

- Track 2: XAI in negotiation and conflict resolution: Conflict resolution (e.g., agent-based negotiation, voting, argumentation, etc.) has been a prosperous domain within the MAS community since its foundation. However, as agents and the problems they are tackling become more complex, incorporating explainability becomes vital to assess the usefulness of the supposedly conflict-free solution. This is the main topic of this track, with a special focus on MAS negotiation and explainability.
Track Chair: Reyhan Aydoğan: Ozyegin University, Turkey
Track 3: Explainable Robots and Practical Applications: Explainable robots have been one of the main topics of XAI for several years. The main interest of this track is to publish the latest works whose focus is notably on (i) the impact of embodiment on explanation, (ii) explainability for remote robots, (iii) how humans receive and perceive explanations by robots, and (iv) practical XAI applications & simulations.
-- Track chair: Yazan Mualla, UTBM, France

- Track 4: XAI in Law and Ethics: complying with regulation (e.g. GDPR) is among the main objectives for XAI. The right to explanation is key to ensuring transparency of ever more complex AI systems dealing with a multitude of sensitive AI applications. This track discusses works related to explainability in AI ethics, machine ethics, and AI & Law.
