Call for Submissions

RuleML2011@BRF Challenge

Challenge-2011 Demo Award: Late-Breaking Demos until 7th Oct.

co-located with the 5th International Rule Symposium RuleML2011@BRF
Nov. 4th, 2011 – Westin Diplomat, Ft Lauderdale, Florida (

Overview and Aim

The RuleML2011@BRF Challenge is one of the highlights at RuleML2011@BRF Conference.The RuleML2011@BRF Challenge is dedicated to practical experiences with rule-oriented applications. In particular, submissions of benchmarks/evaluations, demos, case studies/use cases, experience reports, best practice solutions (e.g. design patterns, reference architectures, models), rule-based implementations/tools/applications, demonstrations of engineering methods, implementations of rule standards (e.g. RuleML, RIF, SBVR, PRR, rule-based Event Processing languages, BPMN+rules, BPEL+rules, …), rules + industrial standards (e.g. XBRL, MISMO, Accord, …), and industrial problem statements are particularly encouraged.

Key themes of the RuleML2011@BRF Challenge include the following:

  • Demos related to the RuleML2011@BRF Track Topics
  • Extensions and implementations of rule standards: W3C RIF, RuleML, SBVR, …
  • Editing environments and IDEs for Web rules
  • Benchmarks and comparison results for rule engines
  • Distributed rule bases and rule services
  • Reports on industrial experience about rule systems

A dedicated track of RuleML2011@BRF Challenge will be focused on the theme:

Combining Rules, Objects, and Ontologies: Implementations and Applications

  • Loose/tight integrations of rules and knowledge bases
  • Knowledge Modelling and Reasoning
  • Real cases and practical experiences

Ideally, demos submitted to the Challenge track should tackle knowledge-rich domain problems. The proposed solution should address such problem using a combination of rule-based modelling and semantic knowledge-based modelling.

Solutions ranging from loosely coupled hybrid systems (i.e. where different frameworks are put together), to unified homogeneous architectures (i.e. where a unified model/semantics, within a single framework, is proposed) will be of great interest for the special track.

Prizes will be awarded to the two best applications from the main focus theme and for the all categories. All accepted demos will be presented in a special Challenge Session.


Submissions to the RuleML2011@BRF Challenge are composed of two parts:

  • an open-source or commercial demo
  • a demo paper describing research, implementation, and technical details of your submission.

Both demo and papers, have to be submitted to the website:

The demo paper consists of 4-8 pages as PDF file in LNCS format (, describing the demo show case, and a link to the demo/show case, e.g. a project site, an online demonstration, a presentation about the demonstration, or a download site for the demonstration.

Demo papers must be in English.

To ensure high quality, submitted papers will be carefully peer-reviewed according to the challenge evaluation criteria.

To better disseminate your work, please also upload your demo in the systems submission website with a brief abstract presentation:

Your demo will be also automatically added to the demo pool on RuleML website to contribute to the further diffusion of your work:

Challenge Evaluation Criteria

Submissions to the RuleML Challenge general Track will be evaluated according to the following criteria:

  • clear exposition of the objectives, outcomes, benefits for going beyond the state of the art in the application domain (25%)
  • demos should demonstrate a good level of effectiveness to manage complex rules according to statistical/analytical/benchmarking evaluations (25%)
  • demos have to demonstrate the results with a concrete example balancing conciseness and completeness (25%)
  • demos should preferably (but not necessarily) be embedded into a web-based or distributed environment (15%)
  • demos should pay attention to end-user interactions, providing an adequate and usable interface that favors a concrete usage of the application (10%).

Submissions focused on this year’s special theme (Knowledge-Based Applications combining Rules and Ontologies) should show the potential and benefits of combining rule-based reasoning and taxonomic/frame/description-logic reasoning in a realistic application. Demos submitted to the Special Theme will be evaluated according to the following criteria:

  • papers should clearly expose the objectives, outcomes, benefits for going beyond the state of the art in the application domain (20%)
  • demos should demonstrate a good level of integration or interaction between rules and ontologies (40%)
  • demos should demonstrate their results with a simple but meaningful case study, balancing conciseness and completeness (20%)
  • demos should preferably be deployed in a web-based or distributed environment where multiple nodes exchange information (10%)
  • demos should pay attention to end-user interactions, providing an adequate and usable interface that favors a concrete usage of the application (10%).

Proceedings and Post-proceedings

Authors are invited to submit original contributions of practical relevance and technical rigor in the field, benchmarks, evaluations, experience reports and show/use case demonstrations of effective, practical, deployable rule-based technologies or applications in web-distributed environments. Papers must be in English.

Accepted papers will be published as CEUR Workshop Proceedings.

Exhibition Room

The RuleML2011@BRF Chairs are currently evaluating the possibility to have an exhibition space where to present the demo live to the participants throughout the Symposium.

More information will be released with the notification of acceptance of the demo papers and demo system.
