A formal ontology of knowing and knowledge

The paper presents a formalisation of one of the leading ontologies in Knowledge Management by the name of Formal Knowledge Management Ontology. After elaborating why the latter ontology is not a formal ontology in the sense of logic and how it might benefit from being logic‐based, we detail a logical theory Formalised Formal Knowledge Management Ontology (F²KMO) that incorporates its main ideas and tenets. In particular, we specify the primitive, that is, undefined terms we assume, the axioms whose role is to fix the meanings of those terms, and a number of definitions that correspond to the definitions one may find in the latest exposition of Formal Knowledge Management Ontology. We show that F²KMO is consistent and prove its usefulness by defining the logical schema of a database based on the theory.
