Sentence compression holds promise for many applications ranging from summarisa- tion to subtitle generation and subtitle gen- eration. The task is typically performed on isolated sentences without taking the sur- rounding context into account, even though most applications would operate over entire documents. In this paper we present a dis- course informed model which is capable of producing document compressions that are coherent and informative. Our model is in- spired by theories of local coherence and formulated within the framework of Integer Linear Programming. Experimental results show significant improvements over a state- of-the-art discourse agnostic approach.
