Implementation of expert system

by Binyala, Krishna Gopal IN BLR SISL

Hello, I am new to drools community... I want to develop an expert system for medical application using drools. can you please let me know how to use history data in drools... Because as far as i know we have to keep all the data in the working memory to access. How should i implement such system? Would be better if you can provide some reference to existing expert system implemented using drools. Thanks in advance. Krishna Gopal In three words I can sum up everything I've learned about life: it goes on... Important notice:This e-mail and any attachment thereto contains corporate proprietary information.

IntelliJ ipr, iml files in subversion break my svn up

by Geoffrey De Smet

Hi guys, Someone removed the *.ipr and *.iml files from svn:ignore and committed their *.ipr, *.iml files. Subversion now refuses to svn up because I got local iml files that conflict with the repository iml files. Since IntelliJ can easily synchronize from the maven2 pom.xml files, I don't think it's a good idea to commit those. When not everyone uses the same version of IntelliJ this can be problematic. Also, I explicitly exclude drools-guvnor out of my ipr file to build faster. Can that change be reverted? I believe the old way is better. -- With kind regards, Geoffrey De Smet

Drools Research Network Launched

by Mark Proctor

http://blog.athico.com/2008/09/drools-research-network.html The number of research projects around Drools is growing, however I've noticed that institutes are generally not aware of each others efforts. For this reason I'm launching the Drools Research Network. This consists of a web page (synced from a wiki page so anyone can edit) that shows all the University stakeholders in Drools and the various research projects. Please do help keep this page up to date and comprehensive. There is also a mailing list that is strictly for institute staff to discuss existing and potential projects, fundings, students and general collaboration to increase and improve Drools related research - if you fit in this category please subscribe. Drools Research Network home page <http://www.jboss.org/drools/research-network.html> The Wiki Page <http://wiki.jboss.org/wiki/DroolsResearchNetwork> The Mailing List <https://www.redhat.com/mailman/listinfo/drools-research>

Drools Research Network

by Mark Proctor

I'm trying to get together a single source of knowledge on all the drools related research going on and various institutes involved. I've setup a wiki page to capture this information, if you are able to add to it please do. It contains a list of the projects, as well as the universities and mentors associated with Drools research. http://wiki.jboss.org/wiki/DroolsInAcademia The wiki page can be edited by anyone who has registered and logged in, the registration link should be on the top of the page.

AAAI Spring Symposium on Intelligent EventProcessing 2009

by Adrian Paschke

[ our apologies should you receive this message more than one time ] AAAI Spring Symposium on Intelligent Event Processing AAAI Spring Symposium Wednesday, March 23-25, 2009 at Stanford University http://icep-aaai08.fzi.de/ ===================================================================== Event-based systems are now gaining increasing momentum as witnessed by current efforts in areas including event-driven architectures, business process management and modeling, Grid computing, Web services notifications, and message-oriented middleware. They become ever important in various application domains, ranging from traditional business applications, like supply-chain management, to the entertainment industry, like on-line gaming applications. However, the current status of development is just the tip of the iceberg compared with the impact that event processing could achieve, as already reported by market research companies. Indeed, existing approaches are dealing primarily with the syntactical (but very scalable) processing of low-level signals and primitive actions, which usually goes with an inadequate treatment of the notions of time, context or concurrency (for example, synchronization). For example, some of the current event processing products are descendents of the active database research that misses efficient (formal) handling of termination, priority ordering, and confluence in rule bases. AI and especially symbolic (for example, logic-based) approaches provide native background for the (formal) representation of the above mentioned missing concepts, enabling evolution from event processing systems into intelligent reactive systems. The work done in temporal logic, spatial reasoning, knowledge representation, ontologies, and so on enables more declarative representation of events and actions and their semantic processing. Contextual reasoning can support complex event prediction. Transactional logic can be used for ensuring the consistency between highly dependent processes in a formal way. On the other side, the heterogeneous and highly distributed nature of event-processing systems, especially on the web, provides new challenges for AI and logics, like the contextualized reasoning over large stream data, scalable mapping of complex structures, or distributed approximate reasoning, to name but a few. Possible symposium topics comprise, but are not limited to: ----------------------------------------------------------- Modeling * Conceptual modeling in event-driven processing * Modeling context in event-driven processing * Event processing languages * Business rules and event-driven processing * Editors for complex events * Complex event processing in highly distributed AI applications * Modeling reactive systems using event-driven processing * Event stream processing * Event-driven architecture for Intelligent Event Processing Discovery * Complex event patterns mining * Temporal aspects in event mining * Prediction of events * Discovery of similar event * Discovery of unknown events * Dealing with missing events Reasoning/Processing * Complex event detection * The role of logic in event processing * Distributed reasoning for events * Reasoning with uncertain events * Reasoning under real-time constraints * Complexity in reasoning for Intelligent Event Processing Advanced Applications * Distributed event processing as a basis for AI applications * Financial trading * Web / Internet of Things * Entertainment * Ubiquitous Computing/ Ambient Intelligence * Business Activity Monitoring * AI in global epidemiology monitoring systems * Other domains Submissions ----------- Papers should be prepared using the two-column AAAI conference paper format. Long papers should be at most six pages; short papers at most two pages. Papers must be submitted electronically via the symposium website. Submissions must be in PDF using the workshop submission system for SSS09, at http://www.easychair.org/conferences/?conf=sss09 More Information http://icep-aaai09.fzi.de/ Important Dates --------------- Deadline for submissions: October 31st, 2008 (12.00 AM, GMT) Notification of acceptance: December 9th, 2008 Camera-ready versions: January 16th, 2009 Symposium: March 23-25, 2009 Organizing Committee --------------------- Nenad Stojanovic, chair, (FZI - Research Center for Information Technologies at the University of Karlsruhe, Germany), Andreas Abecker (FZI, Germany), Opher Etzion (IBM Research Lab, Haifa, Israel).

RuleML-2008: Deadline Extension

by Adrian Paschke

[ our apologies should you receive this message more than one time ] ===================================================================== Due to a number of requests we have to decided to extend the submission deadline by 2 weeks. NEW deadline for paper/demo submission: June 16 ===================================================================== 2008 International RuleML Symposium on Rule Interchange and Applications (RuleML-2008) October 30-31, 2008, Orlando, Florida http://2008.ruleml.org -------------------------------------------------------------------- RuleML-2008 Highlights: - Keynote speakers: * Michael Kifer (State University of New York at Stony Brook, USA), on "Rule Interchange Format: Not Just Syntax". Joint keynote between RuleML-2008 and RR2008. * David Luckham (Stanford University, USA) on complex event processing. * Paul Haley (Haley Ltd) on business rules. * Benjamin Grosof (Vulcan Inc, USA) on the SILK KRR system of the HALO project. (Details at: http://2008.ruleml.org/keynote.php ) - Joint Lunch Panel with the Business Rules Forum about "Rules on the Web" - RuleML-2008 Challenge with prestigious prices (Details at: http://2008.ruleml.org/challenge.php ) (Submissions at: http://ruleml-challenge.cs.nccu.edu.tw/ ) - Lightning talks / Highlight talks Accepted papers will be published in Springer LNCS proceedings and a journal special issue (IEEE TKDE pending) is forthcoming. PRESS RELEASES: http://www.targetwire.com/vpo/rm/ -------------------------------------------------------------------- Call for Papers Collocated with the 11th International Business Rules Forum, the 2008 International Symposium on Rule Interchange and Applications (RuleML-2008) is the second symposium (after last year's highly successful RuleML-2007 - http://2007.ruleml.org/) devoted to work on practical distributed rule technologies and rule-based applications which need language standards for rules operating in the context of, e.g., the Semantic Web, Intelligent Multi- Agent Systems, Event-Driven Architectures and Service-Oriented Computing Applications. The RuleML symposium is a new kind of event where the Web Rules and Logic community joins the established, practically oriented Forum of the Business Rules community (http://www.businessrulesforum.com) to help cross- fertilizing between Web and Business Logic technology. The goal of RuleML-2008 is to bring together rule system providers, representatives of, and participants in, rule standardization efforts (e.g., SBVR, RuleML, RIF, PRR, CL) and open source rules communities (e.g., jBoss Rules, CLIPS/Jess, Prova, OO jDrew, Mandarax, XSB, XQuery), practitioners and technical experts, developers, users, and researchers. They will be offered an exciting venue to exchange new ideas, practical developments and experiences on issues pertinent to the interchange and application of rules in open distributed environments such as the Web. The Symposium gives emphasis on practical issues such as technical contributions and show case demonstrations of effective, practical, deployable rule-based technologies, rule interchange formats and applications as well as discussions of lessons learned that have to be taken into account when employing rule-based technologies in distributed, (partially) open, heterogeneous environments. We also welcome groundwork that helps to build an effective, practical, and deployable rule standard, improve rule technology, provide better understanding of the integration and interchange of rules, and make the current generation of rule engines and rule technology more usable for advanced Web and Service Oriented Architectures. More details in: http://2008.ruleml.org/cfp.pdf -------------------------------------------------------------------- RuleML-2008 Challenge The RuleML-2008 Challenge is one of the highlights of RuleML-2008. It addresses the system demonstration for practical use of rule technologies in distributed and/or Web-based environments. The focus of the challenge is on rule technologies (including rule languages and engines), interoperation and interchange. The challenge offers participants the chance to demonstrate their commercial and open source tools, use cases, and applications. Prizes will be awarded to the two best applications. All accepted demos will be presented in a special Challenge Session. More details in: http://2008.ruleml.org/challenge.php -------------------------------------------------------------------- Important Dates - Paper Submissions due June 16, 2008 (EXTENDED) - Notification of acceptance July 22, 2008 - Final submissions due August 13, 2008 - Symposium date October 30-31, 2008 - RuleML Challenge October 30, 2008 -------------------------------------------------------------------- Submission Site is open: http://www.easychair.org/conferences/?conf=ruleml2008 Submission guidelines: http://2008.ruleml.org/submissions.php Topics of Interest: http://2008.ruleml.org/topics.php Organizing Committee: http://2008.ruleml.org/oc.php Program Committee: http://2008.ruleml.org/pc.php ===================================================================== Co-located with: The 11th International Business Rules Forum http://www.businessrulesforum.com ===================================================================== Sponsored by: Gold level : Vulcan Inc (pending) Silver level: Model Systems Bronze level: STI Innsbruck, ruleCore, JBoss Sponsoring opportunities: http://2008.ruleml.org/sponsoring/ ===================================================================== In Co-operation with: AAAI, W3C, BPM-Forum, Business Rules Forum , ECCAI, OASIS, OMG, Dallas Rules Group, Belgium Business Rules Forum, MIT Sloan CIO Symposium, ACM, ACM SIGART, ACM SIGMIS, ACM SIGWEB, Open Research Society, IEEE Systems Man and Cybernetics Society IEEE SMCS TC on Intelligent Internet Systems IEEE SMCS TC on Distributed Intelligent Systems IEEE Computer Society TC on Autonomous and Autonomic Systems ===================================================================== Media Partners: Springer LNCS, MoDo Marketing =====================================================================
