Call for Papers: 12th International Rule Challenge 2018

Proceedings are available here

The Best Demo Award of the Rule Challenge 2018 was awarded to Theodoros Mitsikas, Sofia Almpani, Petros Stefaneas, Panayiotis Frangos and Iakovos Ouranos for their presentation "Formalizing Air Traffic Control Regulations in PSOA RuleML".


The RuleML+RR 2018 Challenge is one of the highlights of the conference, and seeks to provide competition among innovative rule-oriented applications, aimed at both the research and industrial side. Submissions may present demos related to the RuleML+RR 2018 track topics, supply benchmarks and comparison results for rule engines, illustrate rule- and model-driven engineering, report on industrial experience, present real cases and practical experiences, and realize mobile deployment of rule-based reasoning.

The best paper/demonstration in the Challenge will receive an award of EUR 500!

Key themes of the RuleML 2018 Challenge include, but are not limited to the following:

  • Rule-based Event Processing and Stream Reasoning
  • Business Rules Modeling
  • Graph-Relational Data and Knowledge systems
  • Higher-Order-Logic and Modal-Logic systems
  • Rule/Ontology combinations
  • Modular Rule/Ontology systems
  • Distributed Rule/Ontology systems
  • Ontology-Based Data Access (OBDA) systems
  • Answer Set Programming (ASP) systems
  • Constraint Logic Programming (CLP) systems
  • Blockchain rule systems
  • Defeasible, Argumentation, and Legal systems
  • (Controlled) Natural language interfaces
  • Benchmarks and comparison results for rule engines
  • Distributed rule bases and rule services
  • Rules and model driven engineering
  • Reports on industrial experience about rule systems
  • Real cases and practical experiences
  • Rules in online market research and online marketing
  • Rule-based distributed / multi-agent systems
  • Combining rules with knowledge extraction and information retrieval
  • Rules and social media

  • Giovanni De Gasperis (University of L'Aquila, Italy)
  • Wolgang Faber (Alpen-Adria-Universitaet Klagenfurt, Austria)
  • Adrian Giurca (BTU Cottbus-Senftenberg, Germany)


The challenge seeks high quality, original papers, potentially referencing online material, and ranging between 5-15 pages. Papers must be original contributions written in English and will be submitted at choosing the "Int'l Rule Challenge" track.

To ensure high quality, submitted papers will be carefully peer-reviewed by 3 PC members based on clarity and significance of objectives and demonstration of results.

Submissions should address the following, where applicable:

  • 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 favours 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.

Please upload all submissions in LNCS format. International Rule Challenge 2018 proceedings will be published as CEUR Proceedings and indexed by SCOPUS.
