From one of our latest calls, I got the impression that this concept should not be used for characterising 'tokens' (e.g. lexical occurrences into texts), but rather 'types' (e.g. lexemes) into lexical resources, such as dictionaries. To me, there's a striking difference, since you can predicate very different properties on the two kind of entities. For instance, lexical occurrences (token) are usually grammatically determined, while lexical entries in a dictionary (type) may leave many grammatical attributes open (including the 'word class', in some case).

I think this was already discussed this. Anyway, I fully agree on the distinction, I am simply saying that lexemes, lexical entries, inflected forms, or lexical occurrences in context are all semio:Expressions. This generalization gives us a lot of power for linking different NLP and lexical resources. Given that, they are all different things, and can have specific properties :). 

On the other hand, I am not sure that the type/token distinction is fine enough to support all possible distinctions we need among different kinds of expressions.

Ciao
Aldo
