*******************************************************************************
The 20th International Rule Challenge is the premier forum of the 10th International Conference on Rules and Reasoning (RuleML+RR 2026) designed to benchmark and validate innovative rule-oriented tools, prototypes, and applications. It bridges the gap between theory and practice by fostering competition among solutions tailored to research, industry, and government.
Participants are invited to showcase solutions to complex, real-world problems, or drive the community’s research agenda by proposing new open challenges.
Accordingly, submissions are welcome in two main categories:
- Challenge Proposals: Papers defining rigorous benchmarks, industrial bottlenecks, or novel problems that require rule-based reasoning. Submissions must provide the necessary infrastructure for evaluation, including task descriptions, datasets, and success criteria, highlighting opportunities for rule-based approaches to provide solutions.
- Challenge Solutions: Papers providing empirical evidence of a system's performance such as benchmarking or comparative analyses of rule engines, evaluating rule-based machine learning, or presenting high-impact case studies. Submissions may also cover industrial experiences, rule- and model-driven engineering, or innovative applications.
Key themes of the Rule Challenge include, but are not limited to the following:
- Rule-based machine learning tools and techniques
- Neuro-symbolic reasoning
- Large language models (LLMs) and rule learning
- Rule-based approaches in Artificial Intelligence (AI)
- Rule-based approaches for explainable AI
- Rule-based Complex Event Processing / Recognition (CEP/CER)
- Stream reasoning
- Business rules modelling
- Rule standardization for research, industry and government
- Graph-relational data and knowledge systems
- Higher-order logic and modal logic systems
- Rule and ontology combinations
- Distributed rule systems / Multi-agent systems
- Ontology-Based Data Access (OBDA) systems
- Answer Set Programming (ASP) systems
- Constraint Logic Programming (CLP) systems
- (Controlled) Natural language interfaces
- Rules and model-driven engineering
The challenge seeks high-quality, original papers, potentially referencing online material, and ranging between 8-15 pages. Accepted papers will be published as part of CEUR proceedings and should be in the CEUR-WS.org style template CEURART (1-column variant).
