In knowledge graphs and databases, tworeference commonly manifests as dual identifiers linked by a sameAs relation
In linguistics and cognitive science, the term is used informally to discuss cases where a discourse term
Advantages of tworeference include improved interoperability, redundancy against missing data, and clearer provenance. Drawbacks include increased
