The PROV-K Ontology for tracking provenance of multi-sourced assertions

The PROV-K ontology integrates the PROV Ontology (PROV-O) to represent provenance information of assertions derived from multiple sources using an aggregation algorithm. The PROV-K ontology represents conflicting and supporting evidence, the reliability of an assertion assigned by its creator or external agents, and trust relationships between agents or between an agent and an assertion.
