Knowledge Provenance

Knowledge Provenance (KP) is proposed to address the problem of how to determine the validity and origin of web information by introducing standards and methods for modeling and maintaining the evolution and validity of information/knowledge on the web. Four levels of KP including Static KP, Dynamic KP, Uncertain KP, and Judgmental KP are proposed. This paper focuses on Dynamic KP to address the problem of how to determine the validity of web information over time. A Dynamic Knowledge Provenance ontology is defined, and an example is given to illustrate how to annotate web document with dynamic KP meta and how to use dynamic KP axioms to infer the validity of the web information.
