Connecting the Dots: Document-level Neural Relation Extraction with Edge-oriented Graphs

Usage of EE edges only results in poor performance across pairs. Removal of MM and ME edges does not significantly affect the performance as ES edges can replace their impact. Complete removal of connections to M nodes results in low inter-sentence performance. This behaviour pinpoints the importance of some local dependencies in identifying cross-sentence relations.
