Dear John, Anne and all,
the modelling that John proposes is fine I guess:
"Serjoga" is_a Name
diminutive
diminutive_of "Sergej"
hasConnotation criminal
But I guess that Anne is hinting at the fact that the semantic
contribution of the diminutive suffix (joga???) is systematic across nouns
and does not only hold for "Sergej".
So using the LMF terminology, from an extensional point of view, John's
modelling is fine, but from an intensional point of view we would need
to model the semantic contribution of the diminutive suffix "joga".
I think there is no objection to this, provided that we want to model in
the lexicon "suffixes" as lexical entries and model their semantic
contribution. Provided that we can model the meaning contribution in
terms of a concept in the ontology (e.g. Criminal), this is clearly
feasible.
Best regards,
Philipp.
