Local-to-global GCN with knowledge-aware representation for distantly supervised relation extraction

作者:

Highlights:

• A knowledge-aware framework is proposed to enhance the word representations.

• A piecewise attention method is used to distinguish the local and global information.

• A heterogeneous graph structure is designed to represent and encode sentence bags.
