Assembling rule mashups in the semantic web

This paper introduces RIF Assembler, a tool that reuses knowledge to automatically construct rule-based systems. Our novel approach is based on (a) annotating domain rules with metadata and (b) expressing assembly instructions as metarules that manipulate the annotations. We leverage the power of RIF as a rule interchange format, and of RDF and OWL as languages for rule annotations. RIF Assembler has applications in many scenarios. This paper presents two of them in increasing order of sophistication: a simplistic example related to the health care industry, and an actual usage in the steel industry that involves the construction of a decision-support system driven by business process descriptions.
