Call for Papers: KR meets Machine Learning and Explanation

Machine learning (ML) has seen groundbreaking advancements across countless tasks in recent years, not least with the ongoing development and widespread deployment of large language models (LLMs). Concurrently, with this increase in both power and scope, it has become increasingly important that AI models are designed to be supplemented with explanations such that their outputs can be assessed, understood and modified if necessary. Meanwhile, the field of KR presents an excellent repertoire of technologies for leveraging knowledge in both ML and explanation pipelines. This special track thus aims to focus on the synergistic interactions between KR and these complementary fields of ML and explanation.

We welcome contributions that extend the state-of-the-art at the intersection of KR with either of the fields mentioned above. With regards to explanation, contributions that use KR in the explanation of AI models, or that explain numeric and/or symbolic models themselves, are welcomed. From the ML side, these may also include the use of KR methods for solving ML challenges, the use of ML methods for solving KR challenges or the integration of learning and reasoning towards better modelling, solving or explaining in different tasks. Papers focusing on evaluation protocols and benchmarking of these hybrid solutions will be also welcome.

• Learning symbolic knowledge, such as ontologies and knowledge graphs, action theories, commonsense knowledge, spatial and temporal theories, preference models and causal models
• KR, ML and reasoning in the computation, synthesis, analysis, verification, reuse, and repair of plans
• Logic-based, logical and relational learning algorithms
• ML-driven reasoning algorithms
• Neural-symbolic learning
• Statistical relational learning and KR
• Symbolic reinforcement learning
• The use of KR techniques for supplementing or evaluating LLMs
• LLMs for supporting KR-driven methods
• Knowledge-driven natural language understanding and dialogue
• Learning symbolic abstractions from unstructured data
• Expressive power of learning representations and explanations
• Knowledge-driven decision making and explanations
• Combining discrete and continuous, quantitative and qualitative, logical and probabilistic representations and reasoning methods (e.g., task planning with motion planning) with explanations
• Architectures that combine data-driven techniques and formal reasoning
• KR-driven Explainable AI
• Interpretable ML models intertwined with KR
• Combining KR and ML for enhanced explainability
• Theoretical frameworks for explainability within KR and logic-based systems
• Explainability in dynamic and temporal knowledge representation
• Scalable approaches for real-time explainable reasoning using KR and ML
• Evaluation protocols, metrics, and benchmarks for assessing the quality and clarity of explanations
• Interactive and adaptive explanation frameworks using ML and KR
• Personalisation of explanations through contextual KR, ML and user feedback
• Identifying and mitigating systemic biases in AI explanations through KR
• Hands-on tools and open-source libraries for explanations in real-world settings

Types of Submissions

Submissions to the special track can be either of the following types of technical contributions:

• Long papers (9 pages excluding references)
• Short papers (4 pages excluding references)

Both kinds of papers must be prepared and submitted according to the author guidelines on the submission page before the deadline (more information about submissions will be available in due course at https://kr.org/KR2026/submission.html). These papers must fall into the intersection of KR and either ML or explanation, or both. Papers not meeting this criterion will be identified before the actual reviewing process and will be desk-rejected.

Selected authors will be given the option to showcase their work in the Demo Track alongside their regular presentation slot in a session of the track.
