# EntityN

A comma-separated list of entities to extract. Entities are defined in the grammar file that you set in the ResourceFiles parameter. Replace `N` with the zero-based rank of the entity.

You must associate each entity with a field by setting EntityFieldN.

You cannot use the entity name `entities/ZoneStartN` or `entities/ZoneEndN` (where `N` is a numeric value). These entity names are reserved for use by Named Entity Recognition.

If you do not define an `EntityN` parameter, Named Entity Recognition looks for all entities in all loaded grammar files. In this case, Named Entity Recognition automatically generates the `EntityFieldN` settings from the entities found in grammar files, by converting the entity names to uppercase and replacing slashes with an underscore. For example, for the entity `edk_common_entities/place`, Named Entity Recognition generates the entity field: `EDK_COMMON_ENTITIES_PLACE`.

If you want to use several entities, you can use wildcard expressions instead of typing a lengthy comma-separated list. For example:

    Entity0=place/city1/*,place/city2/*
    EntityField0=CITY
    Entity1=place/*/spabo
    EntityField1=BOLIVIAN_PLACE

You can use the * wildcard to match any number of characters, or the ? wildcard to match a single character.
