Submit your work to the 9th International Web Rule Symposium (RuleML 2015)

Professor at Freie Universitaet Berlin
Dear CEP Colleagues,

I would like to encourage you to submit your research in the field of rules, rule-based reasoning and its applications to RuleML 2015 (

It is an excellent opportunity for a high impact conference publication (; e.g., RuleML is in the top 100 venues for impact factor in CiteSeerX

Also note, that there are several additional collocated events, e.g., the Recommender Systems for the Web of Data Challenge (, the Doctoral Consortium (, the 9th International Rules Challenge with competitive prizes for the best rule base, the Reasoning Web Summer School, RR 2015 and the Workshop on Formal Ontologies meet Industry (, as well as the 25th CADE 2015.

If you are doing your Phd in this field I would like to point you to the Reasoning Web Summer School ( and the joint RuleML/RR Doctoral Consortium ((, where you can submit your Phd paper. Accepted RuleML Phd papers and demo papers will be published in the Challenge proceedings which are listed in DBLP ( and fully indexed e.g. in Scopus.
Also the workshop on Formal Ontologies meet Industry (FOMI 2015) might be relevant for you if you are working on Ontologies (

And, further interesting things will happen at RuleML 2015, such as an ISO Common Logic, OMG API4KB and OASIS LegalRuleML face-to-face meeting. We will also have a Berlin Semantic Web Meetup during RuleML on August 4th. Details will follow soon on the Meetup website:

Thank you and hope to see you in Berlin, Germany in August,

(General Chair RuleML 2015)

The Relationship of Decision Model and Notation (DMN) to SBVR and BPMN (Full Article)

"Publications by James Taylor and Neil Raden[2], Barbara von Halle and Larry Goldberg[1], Ron Ross[7], and others have popularized "Decision Modeling."  The very short summary is that this is about modeling business decision logic for and by business users.
A recent Decision Modeling Information Day conducted by the Object Management Group (OMG)[4] showed considerable interest among customers, consultants, and software vendors.  The OMG followed up by releasing a Request for Proposals (RFP) for a Decision Model and Notation (DMN) specification.[5]  According to the RFP,
"Decision Models are developed to define how businesses make decisions, usually as a part of a business process model (covered by the OMG BPMN standard in Business Process Management Solutions).  Such models are both business (for example, using business vocabularies per OMG SBVR) and IT (for example, mapping to rule engines per OMG PRR in Business Rule Management Systems)."
This quote says a little about how DMN may relate to SBVR[6] and BPMN[3], but there are many more open questions than answers.  How do SBVR rules relate to decisions?  Is there just one or are there multiple decisions per SBVR rule?  Is there more to say about how SBVR and DMN relate to BPMN?
This article attempts to "position" DMN against the SBVR and BPMN specifications.  Of course, DMN doesn't exist yet so the concepts presented here are more the authors' ideas about how these three specifications shouldrelate to each other, than reality.  We present these ideas in the hope that they will positively influence the discussions that lead up to the DMN specification."
