RuleML+RR 2025
the 9th International Joint Conference on Rules and Reasoning
İstanbul, Türkİye
22 - 24 September 2025
rule challenge
General Information
The 19th International Rule Challenge is a standout feature of the RuleML+RR conference, fostering friendly competition among innovative rule-oriented tools, prototypes, and applications tailored to research, industry, and government.
Participants are invited to showcase their solutions to self-defined challenges, but also propose open challenges for the community to tackle.
Accordingly, submissions are welcome in two main categories:
Challenge Proposals. Papers outlining open challenges, interesting problems from academia or industry, or benchmarks relevant to the community. Submissions should include task descriptions, datasets, and evaluation criteria, highlighting opportunities for rule-based approaches to provide solutions.
Challenge Solutions. Papers presenting benchmarking or comparative analyses of rule engines, rule-based machine learning techniques, or case studies. Submissions may also cover industrial experiences, rule- and model-driven engineering, or innovative applications such as deployment of rule-based reasoning in geographically distributed, edge-to-cloud scenarios.
Key themes of the Rule Challenge include, but are not limited to the following:
Rule-based machine learning tools and techniques
Large language models (LLMs) and rule learning
Rule-based approaches in artificial intelligence
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
Submission and Publication
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), available at:
http://ceur-ws.org/Vol-XXX/CEURART.zip
and
https://www.overleaf.com/read/gwhxnqcghhdt
Submitted papers must be original contributions written in English.
Please submit your paper via:
https://easychair.org/conferences/?conf=rulemlrr2025
to the Rule Challenge track.
To ensure high quality, submissions will be carefully peer-reviewed by at least 3 PC members and external reviewers. Submissions should address the following, where possible:
Provide a clear task description, all the relevant datasets, and the evaluation criteria at least in one dimension such as performance, correctness, and completeness (for challenge descriptions).
Explain the objectives, outcomes, benefits as you are going beyond the state of the art in technology, the application domain, etc.
Demonstrate the results with a concrete example balancing conciseness and completeness.
Preferably (but not necessarily) embed the tool in a web-based or distributed environment or a mobile environment.
Present end-user interactions, providing an adequate and usable interface that favors a concrete usage of the application.
Mention the availability of the software and data, data interchange, and possible tool extensions.
Provide a web-link to the project site, online demonstration, or download site.
The best challenge paper will be awarded the RuleML+RR Best Rule Challenge Paper Award 2025. The assessment criteria include originality, creativity together with feasibility.
