The conference

The 4th International Joint Conference on Rules and Reasoning (RuleML+RR 2020) is the leading international joint conference in the field of rule-based reasoning. Stemming from the synergy with the DecisionCAMP summit, which brings together leading decision management authorities, vendors, and practitioners, one of the main goals of RuleML+RR is to build bridges between academia and industry in the area of rule-based reasoning and applications. RuleML+RR 2020 is part of the event “Declarative AI: Rules, Reasoning, Decisions, and Explanations” to be held virtually between 29 June- 1 July 2020.

RuleML+RR 2020 aims to bring together rigorous researchers and inventive practitioners, interested in the foundations and applications of rules and reasoning in academia, industry, engineering, business, finance, healthcare, environment, and other application areas. It provides a forum for stimulating cooperation and cross-fertilization between the many different communities focused on the research, development, and applications of rule-based systems.

RuleML+RR welcomes research from all areas of Rules and Reasoning, including topics from our 2020 theme: explainable algorithmic decision-making. The topics of the conference are:

  • Machine learning approaches involving rules (e.g, extracting rules from Deep Neural Networks or rule-based classification)
  • Rules for knowledge graphs and ontology learning
  • Rule-based approaches to natural language processing
  • Explainable AI approaches based on rules, psychological aspects of rule learning
  • Rules of ethics, biases, laws, policies, and regulations
  • Production & business rule systems
  • Communicating rule models with Decision Model and Notation (DMN)
  • Applications of rule technologies with explainable AI (xAI) elements
  • Foundations of declarative AI architectures and languages
  • Rule-based approaches for intelligent systems and intelligent information access
  • Vocabularies, ontologies, and business rules
  • Ontology-based data access
  • Rule-based data integration
  • Data management and data interoperability for web data
  • Distributed agent-based systems for the web
  • Rule-based approaches to agents
  • Scalability and expressive power of logics for the semantic web
  • Reasoning with incomplete, inconsistent and uncertain data
  • Non-monotonic, common-sense, and closed-world reasoning for web data
  • Non-classical logics and the Web
  • Constraint programming
  • Logic programming
  • Streaming data and complex event processing
  • Higher-order and modal rules
  • Web reasoning and distributed rule inference and execution
  • Rule markup languages and rule interchange formats
  • Rule-based policies, reputation, and trust
  • Rules, blockchain, and smart contracts
  • Scalability and expressive power of logics for rules
  • System descriptions, applications and experiences
  • Rules and human language technology
  • Rules in online market research and online marketing
  • Applications of ontologies and rules in environmental protection
  • Applications in climate change monitoring, mitigation & adaptation
  • Applications in healthcare and life sciences
  • Applications in peace and conflict studies
  • Applications in equity and social welfare
  • Applications in law, regulation, and finance
  • Applications in Digital Twins
  • Industrial applications of rules


We accept the following submission formats for papers:

  • Long papers (up to 15 pages in LNCS style)
  • Short papers (up to 8 pages in LNCS style)

Long papers should present original and significant research and/or development results.

Short papers should concisely describe general results or specific applications, systems, or position statements.

Submitted papers must not substantially overlap with papers that have been published or that are simultaneously submitted to a journal or a conference/workshop with formal proceedings. Double submission to a workshop with informal proceedings is allowed. Papers put on arXiv are also allowed as long as they are not refereed (i.e., formally reviewed by peers).

Submissions: via EasyChair

In addition to regular submissions, RuleML+RR 2020 will include the 14th International Rule Challenge, a Doctoral Consortium, and an Industry Track. RuleML+RR 2020 is co-located with DecisionCAMP 2020 and the 16th Reasoning Web Summer School (RW 2020).


The conference proceedings will be published by Springer in the Lecture Notes in Computer Science series (LNCS).

All submissions must be prepared in Springer's LaTeX style LNCS (

The conference can be looked up in the widely recognized CORE Rank under the acronym RuleML, used before its merger with the RR conference.

The proceedings will be published after the conference.

Journal partnership and best paper award

A selection of the best accepted papers of RuleML+RR 2020 (2-6 papers) will be invited for submission to the Journal of Theory and Practice of Logic Programming (TPLP) published by Cambridge University Press. Accepted papers will also be considered for the best paper award and best student paper awards sponsored by Springer.

Free registration

This year, the registration fee has been dropped. The original fee was up to 550 Euro.
