DEADLINE APPROACHING - 2nd edBPM 2009

by Adrian Paschke

FINAL CALL FOR PAPERS (***DEADLINE APPROACHING***) Deadline paper submissions: 22 May 2009 Call for Papers edBPM 09 2nd International Workshop on Event-Driven Business Process Management 7 September 2009, Ulm, Germany http://icep-edbpm09.fzi.de ------------------------------- Information about the workshop ------------------------------- The recently coined term "Event-Driven Business Process Management" (EDBPM) is nowadays an enhancement of Business Process Management (BPM) by new concepts of Service Oriented Architecture (SOA), Event Driven Architecture (EDA), Software as a Service (SaaS), Business Activity Monitoring (BAM) and Complex Event Processing (CEP). In this context BPM means a software platform which provides companies the ability to model, manage, and optimize these processes for significant gain. As an independent system, CEP is a parallel running platform that analyses and processes events. The BPM- and the CEP-platform correspond via events which are produced by the BPM-workflow engine and by the ? if distributed - IT services which are associated with the business process steps. Also events coming from different event sources in different forms can trigger a business process or influence the execution of the process or a service, which can result in another event. Even more, the correlation of these events in a particular context can be treated as a complex, business level event, relevant for the execution of other business processes or services. A business process - arbitrarily fine or coarse grained - can be seen as a service again and can be "choreographed" with other business processes or services, even between different enterprises and organisations. Loosely coupled event-driven architecture for BPM provides important benefits: - Responsiveness. Events can occur at any time from any source and Processes respond to them immediately, whenever they happen and wherever they happen. - Agility. New processes can be modeled, implemented, deployed, and optimized more quickly in response to changing business requirements. - Flexibility. Processes can span heterogeneous platforms and programming languages. Participating applications can be upgraded or changed without breaking the process model. Authors are invited to submit novel contributions in the above mentioned problem domain. Specifically, the relevant topics include, but are not limited to: - Event-driven BPM: Concepts e.g. Role of event processing in BPM, Business Events: types and representation, Event stream processing in business processes, Data- and event-driven business processes - Design-time CEP and BPM e.g. Modelling events in human-oriented tasks, Semantics/Ontologies for event-driven BPM, BPMN and event processing. - Run-time CEP and BPM e.g. Event pattern detection, BPEL and event processing, Reasoning about unknown/similar events - Applications/Use cases for event-driven BPM e.g. Event-driven monitoring/BAM , Event-driven SLA monitoring ------------------------------- Submission ------------------------------- The following types of submission are solicited: - Long paper submissions, describing substantial contributions of novel ongoing work. Long papers should be at most 12 pages long. - Short paper submissions, describing work in progress. These papers should be at most 6 pages long. Papers should be submitted in the new LNBIP format (http://www.springer.com/computer/lncs?SGWID=0-164-7-487211-0). Papers have to present original research contributions not concurrently submitted elsewhere. The title page must contain a short abstract, a classification of the topics covered, preferably using the list of topics above, and an indication of the submission category (Long Paper/ Short Paper). Papers can be uploaded via the workshop page on easychair, the address can be found on the workshop homepage (http://icep-edbpm09.fzi.de). Selected papers will be published in the Special issue in Journal of Software Process Improvement and Practice for selected BPM 2009 workshop papers. ------------------------------- Important Dates ------------------------------- Deadline paper submissions: 22 May 2009 Notification of acceptance: 16 June 2009 Camera-ready papers: 01 July 2009 Workshops: 7 September 2009 ------------------------------- Organizing Committee ------------------------------- Rainer von Ammon, CITT Regensburg, Germany Opher Etzion, IBM Research Haifa, Israel Heiko Ludwig, IBM TJ Watson Research Center, USA Adrian Paschke, Freie Universitaet Berlin, Germany Nenad Stojanovic, FZI Research Center for Information Technologies at the University of Karlsruhe, Germany ------------------------------- Program Committee ------------------------------- - Marco Aiello, Rijksuniversiteit of Groningen, Netherlands - Karim Ba?na, ENSIAS, Morocco - Martin Bartonitz, Saperion AG, Germany - Luciano Baresi, Politecnico di Milano, Italy - Djamal Benslimane, Universit?

by Adrian Paschke

----------------------------------------------------------------------- Our apologies if you receive duplicates of this posting. Please feel free to distribute it to those who might be interested. ----------------------------------------------------------------------- Call for Papers RuleML 2009 3rd International Symposium on Rules, Applications and Interoperability November 5-7 2009, Las Vegas, Nevada, USA http://2009.ruleml.org/ **************************************************************************** *Latest news * *Student grants of the value of up to $1000 plus free registration * *Keynote by Sandro Hawke, W3C RIF Contact - The Future of Rule Interchange* *Prestigious prizes and new categories in the RuleML Challenge * **************************************************************************** Sponsored by ============================================================================ Franz Inc NICTA (National ICT Australia) Ltd Corporate Semantic Web Logic Programming Associated Ltd Modelsystems Ltd ruleCore ============================================================================ Overview and Aim ============================================================================ The International Symposium on Rules, Applications and Interoperability has evolved from an annual series of international workshops since 2002, international conferences in 2005 and 2006, and international symposia since 2007. This year, the 3rd International Symposium on Rules, Applications and Interoperability (RuleML-2009) takes place in Las Vegas, Nevada, USA, collocated with the 12th Business Rules Forum, the world's largest Business Rules event. RuleML-2009 is devoted to practical distributed rule Technologies and rule-based applications which need language standards for Rules (inter)operating in, e.g., the Semantic Web, Multi-Agent Systems, Event-Driven Architectures, and Service-Oriented Applications. The main goal of RuleML-2009 is to stimulate the cooperation and interoperability between business and research, by bringing together rule system providers, participants in rule standardization efforts, open source communities, practitioners, and researchers. The concept of the symposium has also advanced continuously in the face of extremely rapid progress in practical rule and event processing technologies. As a result, RuleML-2009 will feature hands-on demonstrations and challenges alongside a wide range of thematic tracks, and thus will be an exciting venue to exchange new ideas and experiences on all issues related to the engineering, management, integration, interoperation and interchange of rules in open distributed environments such as the Web. Conference Theme ============================================================================ This year, we particularly welcome submissions that address applications of Web rule technologies for business and information systems. We invite you to share your ideas, results, and experiences: as an industry practitioner, rule system provider, technical expert and developer, rule user or researcher, exploring foundations, developing systems and applications, or using rule-based systems. We invite high-quality submissions related to (but not limited to) one or more of the following topics: Track Topics ---------------------------------------------------------------------------- Rule Transformation and Extraction - Transformation and extraction with rule standards, such as SBVR, RIF and OCL - Extraction of rules from code - Transformation and extraction in the context of frameworks such as KDM (Knowledge Discovery meta-model) - Extraction of rules from natural language - Transformation or rules from one dialect into another Rules and Uncertainty - Languages for the formalization of uncertainty rules - Probabilistic, fuzzy and other rule frameworks for reasoning with uncertain or incomplete information - Handling inconsistent or disparate rules using uncertainty - Uncertainty extensions of event processing rules, business rules, reactive rules, causal rules, derivation rules, association rules, or transformation rules Rules and Norms - Methodologies for modeling regulations using both ontologies and rules - Defeasibility: modeling rule exceptions and priority relations among rules - The relationship between rules and legal argumentation schemes - Rule language requirements for the "isomorphic" modeling of legislation - Rule based inference mechanism for legal reasoning - E-contracting and automated negotiations with rule-based declarative strategies Rule-based Game AI - Rule-based movement, decision making, strategies, behavior design - Rule-based environmental programming, virtual reality - Rules for multi-agent/character games - Rules for serious games - Rule-based agent design Rule-based Event Processing and Reaction Rules - Reaction rule languages and engines (production rules, ECA rules, logic event action formalisms, vocabularies/ontologies) - State management approaches and frameworks - Concurrency control and scalability - Event and action definition, detection, consumption, termination, lifecycle management - Dynamic rule-based workflows and intelligent event processing (rule-based CEP) - Non-functional requirements, use of annotations, metadata to capture those - Design time and execution time aspects of rule-based (Semantic) Business Processes Modeling and Management - Practical and business aspects of rule-based (Semantic) Business Process Management (business scenarios, case studies, use cases etc.) Rules and Cross Industry Standards - Rules in Current Industry Standards, including: - XBRL: Extensible Business Reporting Language - MISMO: Mortgage Industry Standards Maintenance Org - FIXatdl: FIX Algorithmic Trading Definition Language - FpML: Financial products Markup Language - HL7: Health Level 7 - Acord: Association for Cooperative Operations Research and Development (Insurance Industry) - Rules for Governance, Risk, & Compliance (GRC), e.g., rules for internal audit, SOX compliance, enterprise risk management (ERM), operational risk, etc - Rules and Corporate Actions General Rule Topics - Rules and ontologies - Execution models, rule engines, and environments - From rules to FOL to modal logics - Rule-based reasoning with non-monotonic negation, modalities, deontic, temporal, priority, scoped or other rule qualification - Rule-based default reasoning with default logic, defeasible logic, and answer set programming - Graphical processing, modelling and rendering of rules - Rules in Semantic Web Technologies(SW), Artificial Intelligence (AI), Business Process Modeling (BPM), Cloud Computing (CC), Intelligent Agents, Model-Driven Architecture (MDA), Software Engineering (SE), Unified Modeling Language (UML), e-Learning, e-Commerce, ... - Miscellaneous rule topics Case studies, experience reports, and industrial problem statements are particularly encouraged. RuleML-2009 Challenge ============================================================================ The RuleML-2009 Demo Challenge is one of the highlights of RuleML-2009. We invite submissions of demos where rules are used in interesting and practically relevant ways to, e.g., derive useful information, transform knowledge, provide decision support and provide automated rule-based monitoring, enforcement, validation or management of the behavioural logic of the application. The Challenge offers participants the chance to demonstrate their commercial and open source tools, use cases, and applications. Submissions are solicited in these categories: - Benchmarks (test cases, suites) with evaluations of (their own, other) rule engines and/or rule translators, possibly drawing on our growing pool at http://ruleml-challenge.cs.nccu.edu.tw - Case studies (use cases) implemented via engines/translators employing rule standards such as RIF, RuleML, CLIPS, Common Logic, SBVR, and ISO Prolog. We welcome all demos about tools and applications using rules such as: - Derivation rules, including query and integrity rules - ECA rules, including production rules, reaction rules, and rule-based CEP languages Authors of demo are also invited to submit a Challenge demo paper for publications in the conference proceedings, see the submission section below for submission details. Prizes will be awarded to the two best applications from each category. All accepted demos will be presented in a special Challenge Session. A submission to the RuleML Challenge has to meet the requirement that declarative rules explicitly play a central role in the application. Basically this means that: Rules are explicitly represented in a declarative format and they are decoupled from the application (rather than being compiled or hard-coded into the application logic). The demo should preferably (but not necessarily) be embedded into a web-based or distributed environment so that there will be a need for features related to the RuleML conference topics, as listed in the call for papers. For more details and the demo site web link please consult the RuleML-2009 Challenge website: http://ruleml-challenge.cs.nccu.edu.tw Student Grant Awards ============================================================================ Two travel grants are available to students who are authors or co-authors of papers or demos accepted for presentation at the symposium. The grants include free registration and cover travel expenses up to 1000 dollars. Conference Language ============================================================================ The official language of the conference will be English. Submission ============================================================================ Authors are invited to submit original contributions of practical relevance and technical rigor in the field, experience reports and show case/use case demonstrations of effective, practical, deployable rule-based technologies or applications in distributed environments. Papers must be in English and may be submitted at http://www.easychair.org/conferences/?conf=ruleml2009 as: Full Papers (15 pages in the proceedings) Short Papers (8 pages in the proceedings) RuleML-2009 Challenge Demo Paper + Show Cases (3-5 pages in the proceedings) Please upload all submissions as PDF files in LNCS format (http://www.springer.de/comp/lncs/authors.html). To ensure high quality, submitted papers will be carefully peer-reviewed by 3 PC members based on originality, significance, technical soundness, and clarity of exposition. Authors are requested to upload the abstracts of their papers before June 9, 2009 and to upload their complete papers by June 16, 2009. The selected Papers will be published in book form in the Springer Lecture Notes in Computer Science (LNCS) series along with a CD with demo software and documents. The best paper from all submissions will be determined by the PC and a Best Paper Award will be handed over at the Symposium by a Sponsor. All submissions must be done electronically. A selection of revised papers will be resubmitted to a special issue of a journal. Submissions to the RuleML Challenge 2009 consist of a demo paper of 3-5 pages, describing the demo show case, and a link to more information about the demo/show case, e.g. a project site, an online demonstration, a presentation about the demonstration, or a download site for the demonstration. In case of product demos, the link can be password-protected: please submit a password for anonymous login from any Web browser, giving us the permission to pass the password on to 3 PC members. The submissions should satisfy the minimal requirements defined in the topics of interest and preferably exhibit some of the additional desiderata. The more desiderata are met by an application, the higher the score will be. The demos will be evaluated by the RuleML-2009 Program Committee and prizes will be awarded to the two best applications, sponsored by the RuleML Inc. non-profit organization. Review Process ============================================================================ The submitted papers will pass the blind review process. At least three members of the Program Committee will review each submission.

Hi there, I want to set setGlobal in working memory at run time based on derived class, e.g. DerivedOne or DerivedTwo. But it throws following error: Illegal class for global. Expected [org.comp.app.bean.Base], found [org.comp.app.bean.DerivedOne]. It should automatically resolve the derived class. Please let me know if I'm doing something wrong. I'd appreciate your help. Thanks, -KB Here are the classed I'm using in my test project: class abstract Base () { public void init( StatefulSession workingMemory ) { this.workingMemory = workingMemory; workingMemory.setGlobal("app", this); } public void logMe() { System.out.println("From Derived BASE..."); } } class DerivedOne() extends Base{ public void runRules( Object obj) { ObjOne obj1 = (ObjOne)obj workingMemory.insert(obj1); workingMemory.fireAllRules(); workingMemory.dispose(); } public void logMe() { System.out.println("From Derived ONE..."); } } class DerivedTwo() extends Base{ public void runRules( Object obj) { ObjTwo obj2 = (ObjTwo)obj workingMemory.insert(obj2); workingMemory.fireAllRules(); workingMemory.dispose(); } public void logMe() { System.out.println("From Derived ONE..."); } } class Caller() { RuleBase ruleBase = ruleBaseFactory.open(docRules); workingMemory = ruleBase.newStatefulSession(); if (sub==1) { der1 = new DerivedOne(); der1.init(workingMemory); der1.runRules(); } else if (sub==1) { der2 = new DerivedTwo(); der2.init(workingMemory); der2.runRules(); } } //********DRL FILE***** package com.sample import com.sample.app.RuleCaller.Message; global com.sample.app.Base app; rule "using a static function" when eval( true ) then System.out.println( "Message from Rule." ); app.logMe(); end //********DRL FILE***** -- View this message in context: http://www.nabble.com/setGlobal-issue-in-StatefulSession-tp23373329p23373...

Re: rules-dev Digest, Vol 28, Issue 13

by petru simion

I was wondering if anyone knows about any initiative to allow any kind of technology to access rules using drools. I red an article by Mark Proctor, that snows how one can expose the rules via web services. This in turn would allow any application, no matter if it is java or not, to access rules via the web service but some more layers should be added, in order to allow the sender to express what rule base needs to be used, and what facts to be collected from the working memory. I have already a mechanism in place to allow this, but was wondering if maybe there is already something out there that started this kind of initiative. --- On Thu, 4/30/09, rules-dev-request(a)lists.jboss.org <rules-dev-request(a)lists.jboss.org> wrote: From: rules-dev-request(a)lists.jboss.org <rules-dev-request(a)lists.jboss.org> Subject: rules-dev Digest, Vol 28, Issue 13 To: rules-dev(a)lists.jboss.org Date: Thursday, April 30, 2009, 7:09 PM Send rules-dev mailing list submissions to rules-dev(a)lists.jboss.org To subscribe or unsubscribe via the World Wide Web, visit https://lists.jboss.org/mailman/listinfo/rules-dev or, via email, send a message with subject or body 'help' to rules-dev-request(a)lists.jboss.org You can reach the person managing the list at rules-dev-owner(a)lists.jboss.org When replying, please edit your Subject line so it is more specific than "Re: Contents of rules-dev digest..."

It has a split node (XOR) in which I specify a constraint on which a ruleflow-group is to be selected . Insert arraylists as facts in the working memory one by one. The problem I face is that when I insert these arraylists in the same session , it doesn't evaluate every constraint in the split node . The work around I am using , it that I create a new session for every arraylist , this works just fine . But creating a new session always is an overhead . Can you please assist me with this situation . Thank You Harsh Jetly -- View this message in context: http://www.nabble.com/Problem-while-using-RuleFlow-Groups-in-drools-tp188...

One of the requirements in our project was to let a user (anyone who is writing/analysing the rules) find out what other rules a given rule depends upon. There were a few kinds of dependencies: 1) Object Attribute dependency: The attributes of an object being used in the conditional part of a rule might be getting modified in the consequence part of another rule. We wanted all such rules with each rule having its own dependency list. 2) Rule Salience based dependency. A rule having lower salience should be executed only after a higher (if any) salience rule has already been executed. 3) Dependency caused by a specific Rule flow. Rules in a ruleflow group should be executed only if (if any) Split condition gets satisfied. 4) Agenda flow dependency (i.e., one agenda following another) We could not find much support for this in the Drools API. Hence we decided to write our own dependency generator. The tool we are writing caters to first 3 dependencies. We might even handle the 4th one. Since Drools is open source, we thought of contributing our bit towards its development. If the drools team wants I can happily work with them on getting this functionality plugged in the Drools system.

Can drools continue testing even if one of the conditions fail ?

by DroolUser

Hi, I'm using drools for testing if the few attributes of my MO are not null. I construct the rule in the .drl file in following way : rule "name" when condition1 condition2 condition3 condition4 then consequence end I have observed that the drool engine verifies the conditions line by line (in the sequence they have written). The moment condition fails, control comes back to the calling method. I don't want this. I want the control to execute each and every condition whether true or false and maintain a record of passed/failed conditions. Something like this : rule "name" when condition1 log the test result --- This statement should get executed even if condition 1 fails and control should go to condition 2 condition2 log the test result condition3 log the test result condition4 log the test result then consequence end Is this possible in Drools ? -- View this message in context: http://www.nabble.com/Can-drools-continue-testing-even-if-one-of-the-cond...
