International Workshop on Rule Markup Languages for Business Rules on the Semantic Web 14 June 2002, Sardinia (Italy)
in conjunction with the First International Semantic Web Conference (ISWC2002) and hosted by SIG2 (languages and standards) of the OntoWeb Network
See http://tmitwww.tm.tue.nl/staff/gwagner/RuleML-BR-SW.html
Workshop Description:
The workshop will focus on how rule markup languages, such as RuleML, will contribute to the vision of the Semantic Web. The Semantic Web offers a research perspective for automating business processes. Rule markup languages, that allow to express business rules as modular, stand-alone units in a declarative way, and to publish them and exchange them between different systems and tools, will play an important role for facilitating business-to-customer (B2C) and business-to-business (B2B) interactions over the Web.
*Derivation rules* can be included in an ontology to define derived concepts on top of base concepts. In this way, for instance, derived business terms, such as customer categories, may be defined. Whenever a rule refers to an incomplete predicate, for which explicit negative information has to be represented along with ordinary (positive) information, a second negation, supplementing negation-as-failure, is needed (as in the formalism of extended logic programs). Using this negation in the head of a rule, one can express conflicting rules that may defeat each other. Such a language for *defeasible rules* is useful to represent business rules allowing for exceptions.
In addition to derivation rules, there is another type of rule which allows to specify the reactive and communicative behavior of a system or agent: *Reaction rules* -- in other contexts also called 'event-condition-action (ECA) rules' or 'triggers'. Business rules that specify the various steps of a business process can be encoded in the form of reaction rules. A general markup language for business rules has to accommodate these different types of rules and support their interoperation.
Topics of Interest:
We encourage submissions on all topics related to rule markup languages. In particular, we solicit papers on
* reaction rules on the Semantic Web - event/action languages - execution models * defeasible rules on the Semantic Web - defeasible concept definitions in ontologies - resolving conflicts in triggered action sets
Other suggested topics include:
* tools and systems for rules on the Semantic Web * combining rules and ontologies * integrating rules and description logics * multiple language rules (Prolog, SQL, OCL, XML, RDF, etc.) * future application scenarios based on RDF, ontologies and rules * RuleML-based applications * deployment of rule-based applications on the Web * rule-based software agents and the Semantic Web * connecting rules to legacy knowledge bases * integrating rule bases and distributed fact bases * handling lineage and reliability of distributed information * processing negative information with negation(s) * using URIs in rules * XSL transformations of rules * <yourTopic ... >
Submission:
We invite articles of no more than 15 pages length describing original completed work, work in progress, or interesting problems or use cases. Submitted papers will be fully refereed based on the originality and significance of the ideas presented as well as on technical aspects. Publication of accepted papers in the form of post-workshop proceedings is being planned.
Please email your submission by 26-April-2002 in PDF or Postscript format to one of the workshop co-chairs.
