Abstract. Enhancing Semantic Web technologies with an ability to express uncertainty and imprecision is widely discussed topic. While SWRL can provide additional expressivity to OWL-based ontologies, it does not provide any way to handle uncertainty or imprecision. We introduce an extension of SWRL called SWRL-F that is based on SWRL rule language and uses SWRL’s strong semantic foundation as its formal underpinning. We extend it with a SWRL-F ontology to enable fuzzy reasoning in the rule base. The resulting language provides small but powerful set of fuzzy operations that do not introduce inconsistencies in the host ontology. Keywords: SWRL, SWRL-F, fuzzy logic, fuzzy rules, fuzzy, rule language, risk.
