# Dependancy Parsing
A dependency structure consists of dependency relations, which are binary and asymmetric.
For example: John hit the ball
A relation consists of
- a head (H) - hit
- a dependent (D) - ball
- a label identifying the relation between H and D - Object

Dependency parsing outputs a list of dependencies between the words in the sentence. It brings an interface to semantics "Who did what to whom"
