RuleML 2009 Invited Speakers

Sandro Hawke, W3C@MIT
Bringing Order to Chaos: RIF as the New Standard for Rule Interchange

Abstract: As the W3C Rule Interchange Format (RIF) nears completion, we consider what it offers users and how it may change the design of systems and change the industry. More than just a standard XML format for rules, RIF is integrated with the W3C Semantic Web technology stack, offering a vision for combining some of the best features of the Web with the best features of rule systems. RIF is designed to directly handle rule bases which use only standard features, but it can be extended. Some example extensions and possible areas for future standards work will be discussed.

About the speaker: Sandro Hawke leads the effort to develop a standard for rule interchange at the World Wide Web Consortium at MIT (W3C/MIT), where he has been a member of the Semantic Web staff since 2000. Working with representatives from academia and industry, he organized and helped guide the Working Group which produced the Rule Interchange Format (RIF), an emerging standard. His professional focus is on developing global-scale decentralized systems, leveraging both Web Architecture and Knowledge Representation. He strongly believes in running code, and wrote the Surnia OWL reasoner (in Python and FOL axioms), the Ontaria ontology directory and browser (in SWI-Prolog), and is currently developing a RIF translator called riftr.

Paul Vincent, TIBCO Software
Why Rules Matter in Complex Event Processing... and vice versa

Abstract: Many commercial and research CEP solutions are moving beyond simple stream query languages to more complete definitions of “process” and thence to “decisions” and “actions”. And as capabilities increase in event processing capabilities, there is an increasing realization that the humble “rule” is as relevant to the event cloud as it is to specific services. Less obvious is how much event processing has to offer the process and rule execution and management technologies. Does event processing change the way we should manage businesses, processes and services, together with their embedded (and hopefully managed) rulesets?

About the speaker: Paul Vincent has been involved in rule processing since his decades-ago Computer Science undergraduate and postgrad days, firstly in “expert systems” and “intelligent knowledge based systems”, through to rule-based applications, rule management and decision services, and most recently complex event processing. Despite appearances, this apparent “fad chasing” has been totally innocent and unplanned. At TIBCO he is CTO for Business Rules and CEP in the “skunkworks” Quantum Leap group, exploiting rule-based CEP technologies for advanced high-performance event-driven business processes, while also occasionally contributing to the OMG PRR and W3C RIF rule standards and the EPTS Working Groups. He drily and irrelevantly blogs (which someone commented once as “off the wall”) at http://tibcoblogs.com/cep as his sole contribution to “Web 2.0”.

Donald Chapin, Business Semantics Ltd
Terminology: the Semantic Foundation for an Organization’s Executable Rules

Abstract: For rules to be applied consistently they have to be expressed consistently — they need common terminology. It is also essential that the semantics and organization’s business definitions, policies and rules is carried forward into the IT systems that support the organization.

This talk introduces the general principles of terminology and the role played by terminology in Semantics of Business Vocabulary and Business Rules (SBVR), the specification published by the Object Management Group (OMG) in 2008.

The major topics are:

  • Introduction to the discipline of terminology (sister discipline of lexicography) and the fundamentals of ISO terminology standards. The terminology capabilities that SBVR adds to ISO terminology standards.
  • The significance of the industry trend to use terminology to improve communication and the quality of document/content authoring.
  • How SBVR supports the people who operate the organization in specifying the meaning of business policies and rules in the terminology they use every day.
  • An overview of the transformation from an organization's business policies and rules — as expressed in its managed terminology — to executable data and rules, while maintaining the organization’s semantics.

About the speaker: Donald Chapin has pioneered methods for defining concepts, structuring knowledge, and expressing business rules in the language of the business since the beginning of his career. Having co-founded a manufacturing company with responsibility for its organization, processes, management system and recordkeeping, he proceeded to bring that business orientation to the design of IBM's first training program for business application development. He continues to enable organizations to document and manage their business vocabularies, policies, rules, services and processes as a strategy, tools and methods consultant, workshop facilitator, trainer, mentor, and quality reviewer.

Donald Chapin has been the chair of the OMG Finalization Task Force for the Semantics of Business Vocabulary and Business Rules (SBVR), co-chair of the OMG Business Modeling & Integration Domain Task Force, and the OMG Liaison to ISO TC 37 (Terminology and other Language and Content Resources).
