Call for Papers: The 9th International Web Rule Symposium (RuleML 2015)

December 18, 2014 12:35:43 PM
The annual International Web Rule Symposium (RuleML) is the leading international event in the field of rules and their applications. RuleML 2015, the ninth event in this series, will be held in Berlin, Germany, August 3-5 in conjunction with the Conference on Automated Deduction (CADE), the Conference on Web Reasoning and Rule Systems (RR) and the Reasoning Web Summer School (RW).
RuleML 2015 will host multiple tracks on Complex Event Processing, Existential Rules and Datalog+/-, Industry, Legal Rules and Reasoning and Rule Learning, as well as hosting the 9th International Rule Challenge and the 5th RuleML Doctoral Consortium.
  • Co-located with:
    CADE 2015 RR 2015 Reasoning Web 2015 FOMI 2015
  • Sponsored by:
  • In cooperation with:
    TCSEM CSW Group Berlin


RuleML 2015 welcomes practitioners, interested in the theory and applications of rules in academic research, industry, engineering, business and other diverse application areas. It provides a forum for stimulating co-operation and cross-fertilization between the many different communities focused on the research and development of rule-based systems.
The symposium's areas of research and development have helped drive rapid progress in technologies for practical rule and event processing in distributed enterprise, intranets, and open distributed environments. Industry practitioners, rule-system providers, users of rules, technical experts and developers, and researchers who are exploring foundational issues, developing systems and applications, or using rule-based systems are invited to share ideas, results, and experiences.

RuleML 2014 Report

December 10, 2014 9:50:51 AM
Rules and Rule Learning were popular topics at the main European AI event in 2014.

Rules have been widely used, from Rule-Based Data Access to Complex Event Processing. RuleML acts as an interoperation bridge, where RuleML rules can be characterized along multiple dimensions. The specification of Deliberation RuleML permits the MYNG configuration of customized language schemas.

The RuleML 2014 Symposium, in conjunction with ECAI 2014, brought together international delegates in Prague, Czech Republic. Our photo selection of the RuleML 2014 Keynote and Tutorial Speakers, here, gives an impression of five event highlights. The Rules on the Web Springer proceedings, edited by Antonis Bikakis, Paul Fodor, and Dumitru Roman, are available in print and online. This year's International Rule Challenge included the RuleML 2014 Rulebase Competition, requiring Deliberation RuleML 1.01 validation. The Rule Challenge and Doctoral Consortium CEUR proceedings, edited by Theodore Patkos, Adam Wyner, and Adrian Giurca, are freely available online.

RuleML 2014 was a full success according to the verbal and email feedback obtained during and after the event. Most presentations are now uploaded from the schedule page. Inspiring discussions in sessions with more than 60 participants extended into the breaks and evenings, including with ECAI participants who joined in from parallel sessions. Many new contacts were made within RuleML as well as with the Czech and the international ECAI community. RuleML Technical Groups found broad interest, also amongst AI colleagues, especially the Reaction RuleML TG and the Uncertainty Reasoning TG. The single most popular topic was probably Rule Learning, covered by a keynote, a tutorial, papers, and demos. Stay tuned for more to come in RuleML 2015.

RuleML 2014 Awards (2)

September 1, 2014 10:41:08 AM
By an unfortunate error, our announcement on Awards does not include the RuleML2014 Runner-up Best Paper Award.

RuleML2014 Runner-up Best Paper Award

was awarded to Mario Luca Bernardi, Marta Cimitile, Chiara Di Francescomarino, and Fabrizio Maria Maggi for their work Using Discriminative Rule Mining to Discover Declarative Process Models with Non-Atomic Activities
They investigate usage of discriminative rule mining in the discovery task, to characterize business process lifecycles that determine constraint violations and lifecycles that ensure constraint fulfillments. An implementation of their approach is in use at Volvo IT Belgium.

RuleML 2014 Awards

August 22, 2014 10:12:37 AM
organization committee is happy to announce the 2014 Awards of Excellence recipients and would like to congratulate all winners!

RuleML Best Paper Award

Went to Marco Calautti, Sergio Greco, Cristian Molinaro and Irina Trubitsyna for their work Checking Termination of Logic Programs with Function Symbols Through Linear Constraints
They present the novel class of rule-bounded programs. While current techniques perform a limited analysis of how terms are propagated from an individual argument to another, their technique is able to perform a more global analysis, thereby overcoming several limitations of current approaches. They alsopresent a further class of cycle-bounded programs where groups of rules are analyzed together.

RuleML Challenge Award

Went to Benjamin Dönz and Harold Boley for their work Extracting Data from the Deep Web with Global-as-View Mediators Using Rule-Enriched Semantic Annotations.
To allow automated interaction with databases on the Deep Web, thei application uses rules that exploit features (e.g. HTML attribute values) to identify elements on a Web page and infer semantic annotations that link these elements to known concepts (e.g. query parameters or result values). Deep Web Mediator demostrates the performance of this approach in a classified-advertising use case. The system is able to answer complex queries by transforming and forwarding them to multiple sites as well as integrating the local results.

RuleML Challenge Runner-up Award

Went to Iosif Viktoratos, Athanasios Tsadiras and Nick Bassiliades for their work Geosocial SPLIS: A Rule-Based Service for context-aware point of interest exploration.
They build an innovative location based social networking service allowing organization to assert their own properties and group targeted offering policies e.g. "If a person is unemployed and day is Friday then spaghetti price has discount 10%". These offering policies are represented as rules in RuleML. The system evaluates rules on the fly depending on regular user's context and delivers personalized offers to them.

RuleML Rulebase Competition Award

Went to Mohammad Sadnan Al Manir and Christopher J.O. Baker for their RuleML rulebase OffshoreHoldingAnalytics.ruleml presented in Offshore Holdings Analytics Using Datalog+ RuleML Rules
In April 2013, the International Consortium of Investigative Journalists (ICIJ) exposed the details of 130,000 offshore accounts. Although there are legitimate businesses which use such accounts, there exist a number of accounts which are possibly linked to international tax fraud and money laundering. The ICIJ investigation was based on 2.5 million records of offshore holdings linked to 170 countries. All these records have been made available for further examination and analysis. Based on over 2.5 million records of offshore holdings linked to 170 countries, a set of facts, rules and queries have been formulated in Datalog+ RuleML 1.01/XML and these rules have been tested and validated against the Relax NG schema for Datalog+ in RuleML 1.01/XML.

RuleML Student Travel Support Awards

Were offered by the Artificial Intelligence Journal to Marco Calautti and Shashishekar Ramakrishna.
