** apologies for cross-posting ** ==== Call for Papers: Rule-based Recommender Systems Challenge ====
A challenge of RuleML 2015, 2-5 August 2015 Berlin URL: http://2015.ruleml.org/recsysrules-2015.html co-located with: - The 11th Reasoning Web Summer School (RW 2015), July 31 - August 4, 2015 http://reasoningweb.org/2015 - 9th International Conference on Web Reasoning and Rule Systems (RR 2015), August 4-6, 2015 http://www.rr-conference.org/RR2015 - 25th International Conference on Automated Deduction (CADE-25), August 1-7, 2015 http://www.cade-25.info/ - 7th Workshop on Formal Ontologies meet Industry (FOMI 2015), August 5th http://www.csw.inf.fu-berlin.de/fomi2015/ This challenge has two focus areas: * rule learning algorithms applied on recommender problems * using the linked open data cloud for feature set extension The challenge uses a semantically enriched version of the MovieLens dataset. In addition to the standard metrics of recommender performance, the challenge aims to assess the understandability of the rule set generated by the participating rule-based systems. == Task == The participating systems are requested to find and recommend a limited set of 5 items that best match a user profile. * The participants will be provided with a semantically enriched version of the MovieLens dataset. * It is mandatory that a participating solution either uses the linked open data cloud to further extend the feature set or is a rule-based classifier. Both options simultaneously are preferred. * A scorer is provided by the organizers so that the participants can check their progress. * Challenge submission will consist of the set of additional recommendations (top-5 movies) for each user from the train dataset and a file containing the rules that lead to the prediction (rule based classifiers only, PMML RuleSet model preferred but not required). == Judging and Prizes == Four prizes, totalling to 500 USD, will be given: * best recommender performance will be given to the paper with the highest score in the evaluation (main prize) * most understandable ruleset (only rule-based submissions eligible) * best aggregate diversity * most original approach, selected by the Challenge Program Committee with the reviewing process == Proceedings == Rule Challenge 2015 proceedings will be published as CEUR Proceedings and indexed by SCOPUS. == Important dates == * Paper and result submission: May 23, 2015 * Author Notification: June 6, 2015 * Challenge: 2-5 Aug, 2015 == Organisers == * Jaroslav Kucha? (Czech Technical University, Prague) * Tommaso di Noia (Politecnico di Bari, Italy) * Heiko Paulheim (University Mannheim, Germany) * Tomáš Kliegr (University of Economics, Prague) ------------------------------- The annual International Web Rule Symposium (RuleML) is an international conference on research, applications, languages and standards for rule technologies. RuleML is the leading conference to build bridges between academia and industry in the field of rules and its applications, especially as part of the semantic technology stack.
