Data.Alpino.DepStruct.Triples

Definition and extraction of Alpino dependency triples.

Dependency triples

data DepTriple

The DepTriple type represents a dependency that occurs in a dependency structure. The triple consists of the head, a dependent, and the relation between the head and the dependeny. For convenience, the triple is composed of two DepTripleComponent instances: the first representing the head and its role in the relation, the second representing the dependant and its role in the relation.
