Hmm.. (02)
When you put Linked Data in the mix its about terms rather than words
i.e., terms being words that have the duality of denotation and
reference baked in. Thus, you can use owl:sameAs to express coreference
in ABox oriented statements about entities. (03)
For TBox or RBox oriented descriptive statements (for entity types and
relation types, respectively) you have owl:equivalentClass and
owl:equivalentProperty, respectively. (04)
