RuleML+RR 2022 26th-28th September in Berlin, Germany Part of DeclarativeAI and co-located with DecisionCAMP and the 18th Reasoning Web Summer School The RuleML+RR 2022 conference is part of the event “Declarative AI: Rules, Reasoning, Decisions, and Explanations” and is co-located with DecisionCAMP 2022 and the Reasoning Web Summer School. It features the RuleChallenge and a Doctoral Consortium as associated events. The 6th International Joint Conference on Rules and Reasoning (RuleML+RR 2022) is the leading international joint conference in the field of rule-based reasoning. One of the main goals of RuleML+RR is to build bridges between academia and industry in the area of semantic reasoning. See https://2022.declarativeai.net/ . RuleML+RR 2022 aims to bring together rigorous researchers and inventive practitioners, interested in the foundations and applications of rules and reasoning. It provides a forum for stimulating cooperation and cross-fertilization between different communities focused on the research, development, and applications of rule-based systems. We are looking for high-quality papers related to theoretical advances, novel technologies, and artificial intelligence applications that involve rule-based representation and reasoning.

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. Submissions to the RuleML+RR conference 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). All submissions must be prepared in Springer's LNCS style (http://www.springer.com/comp/lncs/authors.html). Publication The conference proceedings will be published by Springer in the Lecture Notes in Computer Science series (LNCS) after the conference. A selection of the accepted papers of RuleML+RR 2021 will be invited for submission to the Journal of Theory and Practice of Logic Programming (TPLP) published by Cambridge University Press. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16th International Rule Challenge The Rule Challenge solicits high quality papers focussing on practical problems - or challenges - related to rule-based approaches. We welcome two different kinds of submissions: (1) Challenge descriptions: papers describing open challenges, interesting problems from academia or industry, and benchmarks which are of interest for the community and can be solved by rule-based approaches, including task description, datasets, and the evaluation criteria; (2) Challenge solutions: Papers supplying benchmarking or comparison results for rule engines, rule-based machine learning techniques, illustrating rule- and model-driven engineering, reporting on case studies and industrial experiences, and realizing mobile deployment of rule-based reasoning. All submissions must be formatted in the LNCS style and should be between 8-15 pages. The paper submission deadline is July 7th, 2022. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . The Doctoral Consortium hosted at RuleML+RR 2022 aims at promoting student research in Artificial Intelligence, especially research on rule-based formalisms and reasoning. It offers PhD students close contact with leading experts in the field, as well as the opportunity to present and discuss their ideas in a dynamic and friendly setting. We invite PhD students at an early or intermediate stage of their PhD studies as well as exceptional Master’s students who are interested in pursuing a PhD to submit papers describing their research on any of the topics of interest to RuleML+RR 2022. RuleML+RR DC papers are limited to 8 pages written in English following the LNCS format and submitted electronically in PDF format jointly with a maximum 2 pages CV. Details can be found in the RuleML+RR 2022 DC CfP (https://2022.declarativeai.net/events/ruleml-rr/ruleml-rr-dc). The paper submission deadline is July 7th, 2022 (titles/abstracts are due on June 30, 2022). . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
