Hybrid Human-Artificial Intelligence (HHAI) is an international conference series that focuses on the study of Artificial Intelligence systems that cooperate synergistically, proactively and purposefully with humans, amplifying instead of replacing human intelligence. HHAI aims for AI systems that work together with humans, emphasizing the need for adaptive, collaborative, responsible, interactive and human-centered intelligent systems. HHAI systems leverage human strengths and compensate for human weaknesses, while taking into account social, ethical and legal considerations.

HHAI 2025 will be held on June 9–13, 2025, in Pisa, Italy, and is the fourth conference in the series.

The HHAI field is driven by developments in AI, but it also requires fundamentally new approaches and solutions. Thus, we encourage collaborations across research domains such as AI, HCI, cognitive and social sciences, philosophy and ethics, complex systems, and others. In this fourth international conference, we invite scholars from these fields to submit their best original – new as well as in progress – works, and visionary ideas on Hybrid Human-Artificial Intelligence.

Submission Guidelines

In this conference, we wish to stimulate the exchange of novel ideas and interdisciplinary perspectives. To do this, we will accept three different types of papers:

• Full papers present original, impactful work (12 pages excluding references)
• Blue sky papers present visionary ideas to stimulate the research community (8 pages excluding references)
• Working papers present work in progress (8 pages excluding references)

Submissions of full, blue-sky, and working papers should be original work without substantial overlap with pre-published papers. All submissions should adhere to IOS formatting guidelines. Papers should be written in English and detailed submission instructions can also be found here.

List of Topics

We invite research on different challenges in Hybrid Human-Artificial Intelligence. The following list of topics is illustrative, not exhaustive:

• Human-AI interaction, interpretation and collaboration
• Adaptive human-AI co-learning and co-creation
• Learning, reasoning and planning with humans and machines in the loop
• User modeling and personalisation
• Integration of learning and reasoning
• Transparent, explainable, and accountable AI
• Fair, ethical, responsible, and trustworthy AI
• Societal awareness of AI
• Multimodal machine perception of real-world settings
• Social signal processing
• Representations learning for Communicative or Collaborative AI
• Symbolic representations for human-centric AI
• Human-AI Coevolution
• Foundation models and humans
• Human cognition-aware AI
• Decentralized human-AI systems
• Reliability and robustness in human-AI systems
• Applications of hybrid human-AI intelligence

We welcome contributions about all types of technology, from robots and conversational agents to multi-agent systems and machine learning models.
