For **nominal multi-word expressions**, we use a primary distinction concerning the naming convention that links the expression and the entity or entities the expression can refer to. The starting intuition is that one can distinguish:
- (1) **entity names** : some nominal MWEs work as the **direct name of a specific entity** (for instance *Anna Duval*)
- (2) versus **instantiable concept names**, working as the name of a concept, which can be used to refer to instances of this concept (e.g. *neural network*).

- (1c) but also names which serve to designate unique abstract entities (sometimes called "unica"), such as abstract simple nouns ("taxidermy") or abstract MWEs ("Euclidean geometry", "machine translation"): although not intuitively classified as proper nouns, they are still the name of a specific entity (or of a concept with one instance only), for which the speakers have to learn the naming convention.
In NLP, cases (1a) and (1b) fall into the badly named category of **named entities** (we keep this term in the following, although "named entity" should refer to the entity and not the name: we will use it, as usual in the NLP community, for entity names).
En TAL, seul les cas (1a) et (1b) relèvent de ce qui est appelé **entité nommée** (il est notoire que le terme "entité nommée" ajoute de la confusion, cf. il désigne l'entité et pas le nom. L'expression linguistique *Anna Duval* est un nom d'entité et pas une entité nommée, mais nous conservons dans toute la suite le terme consacré "entité nommée").

En outre, les entités nommées en TAL sont associées à un type sémantique prédéfini.
Dans les annotations PARSEME-FR, nous avons souhaité conserver la distinction claire entre:
