RuleML+RR 2026 – International Joint Conference on Rules and Reasoning: Everything You Need to Know

What Is RuleML+RR 2026?

RuleML+RR 2026 is the International Joint Conference on Rules and Reasoning, taking place from August 24 to August 26, 2026, in Vilnius, Lithuania. This annual event merges two established communities—the RuleML Symposium and the International Conference on Rules and Reasoning (RR)—into a single forum dedicated to rule-based reasoning, knowledge representation, and AI reasoning systems. The conference is organized by leading researchers in rule technologies and logic programming, with support from the RuleML Association and academic partners in Europe.

The conference matters because it addresses a critical layer of modern artificial intelligence: the ability to encode, interpret, and execute logical rules. While much of the AI industry focuses on statistical learning and neural networks, RuleML+RR 2026 provides a dedicated venue for symbolic AI, where explainability, formal verification, and deterministic reasoning take center stage. This makes the event uniquely relevant for professionals working on systems that require auditable decision-making, such as regulatory compliance, legal reasoning, and enterprise knowledge management.

Why It Matters for AI Professionals

For AI practitioners, RuleML+RR 2026 offers a rare opportunity to engage with the foundational logic that underpins many hybrid AI architectures. As organizations increasingly demand transparency in AI outputs—driven by regulations like the EU AI Act—rule-based reasoning provides a complementary approach to black-box models. Attendees will gain insights into how rule engines, logic programming languages, and semantic web reasoning can be integrated with machine learning pipelines to produce more robust and interpretable systems.

The conference also bridges research and practice. By bringing together academics and industry engineers, RuleML+RR 2026 facilitates knowledge transfer on topics such as business rule management, ontology-based data access, and knowledge graph reasoning. For professionals building decision-support systems or working with formal knowledge representation, this event provides direct access to the latest tools, standards, and methodologies in the field.

What to Expect

RuleML+RR 2026 will feature a comprehensive program covering the full spectrum of rule-based and reasoning technologies. While the full agenda is yet to be announced, the conference traditionally includes the following components:

• Research paper presentations on rule languages, logic programming, and reasoning algorithms
• Industry track showcasing practical deployments of rule systems in enterprise and government
• Tutorials and workshops on topics such as semantic web reasoning, answer set programming, and rule-based AI
• Keynote talks from leading academics and practitioners in symbolic AI and knowledge representation
• Poster and demo sessions for emerging work and prototype systems
• Doctoral consortium for early-career researchers in rules and reasoning

Specific keynote speakers and workshop details are to be announced on the official website as the event approaches.

Who Should Attend

RuleML+RR 2026 is designed for a diverse audience spanning academia and industry. Researchers in knowledge representation, logic programming, and semantic web technologies will find the technical program essential. Software engineers and architects working on rule engines, business rule management systems, or knowledge graphs will benefit from the applied sessions and networking opportunities. Additionally, data scientists and AI ethicists interested in explainable AI and formal verification will discover relevant methodologies. The conference is also valuable for graduate students seeking to understand the state of the art in rule-based reasoning and for decision-makers evaluating symbolic AI for their organizations.
