An annotation for the Wikipedia page (i.e., canonical name) associated with
This is the recommended annotation to use for entity linking that links to Wikipedia.
Attaches to a token, as well as to a mention (see (@link MentionsAnnotation}).
Returns the type associated with this annotation. This method must
return the same class type as its value type parameter. It feels like
one should be able to get away without this method, but because Java
erases the generic type signature, that info disappears at runtime.
