RuleML + RR 2020

Poster and Interactions


RuleML+RR 2020 calls for additional poster presentations and interactions related to theoretical advances, novel technologies, and innovative applications concerning knowledge representation and reasoning with rules.

The International Joint Conference on Rules and Reasoning (RuleML+RR) is the leading international joint conference in the field of rule-based reasoning. Stemming from the synergy between the well-known RuleML and RR events, one of the main goals of this conference is to build bridges between academia and industry. 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 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 2020 is part of Declarative AI 2020. With its general topic "Declarative AI", the event brings together the 4th International Joint Conference on Rules and Reasoning (RuleML+RR 2020), DecisionCAMP 2020, and the Reasoning Web Summer School (RW 2020).

There are two types of submissions for the Posters & Interactions track of RuleML+RR 2020:

  • (1) Interactions displaying promising but possibly preliminary work on late-breaking, practical system implementations and applications using an interactive presentation format (including live laptop-screen software demos, media supported Q&A, videos, etc.)
  • (2) Posters (max size: A0) addressing display promising but possibly preliminary work on relevant topics.

Participants are welcome to address both of the above aspects in their submission/presentation, if suitable.

In particular, young researchers and PhD students are encouraged to submit to the Poster & Interactions track of RuleML+RR 2020. Each submission is accompanied by a short paper (max. 5 pages) describing the topic of the display. Poster papers and Interaction papers can be submitted electronically in PDF format via EasyChair (select the Posters & Interactions track):

Please upload all submissions in LNCS format ( To ensure high quality, submitted papers will be carefully peer-reviewed by the PC members based on significance and relevance for the community. Accepted papers will be published online as part of Proceedings, which are broadly indexed, e.g., by SCOPUS and listed in standard bibliographic databases such as DBLP.
