[Corpora] [Corpora-List] Named entities and abstract codes

[Satoshi Sekine]

Dear Leon,


I think I'm not directly answering your question (asking related literature), but I just want to give a comment. If you are building an application which needs to recognize abstract codes, don't be afraid to make such category. We don't have to start designing it from the definition of "named entity". Rather, we should start design it from what is important for your application. We may be able to call them "targets of interest" or "important designator".

Actually, when we designed 200 extended named entity, which includes color name, animal, ID number (like yours), job title etc, we got comments that these are not named entities. We spent sometime trying to coin a new term to describe it, but it was not successful. (if any of you come up with a good name, please let me know).

When we talk about "Lars von Trier", it is fairly uncontroversial to claim that this fits the rigid designator definition well. But using a less descriptive, more abstract phrase, like a document identifier, does the definition fit just as well? Is there some related literature?
