Contextualization via Qualifiers


A common method for contextualizing facts in knowledge graph formalisms is
by adding property-value pairs, qualifiers, to the facts in the knowledge

knowledge graphs when the qualifier instead contextualizes the base fact, as
in limiting the applicability of the fact to some time period or providing a
confidence level for the fact. Contextualization should instead by done in
a more principled manner and accompanied by tools that lessen the burden on
consumers of knowledge graphs.
