A Hierarchical Framework for Relation Extraction with Reinforcement Learning
national conference on artificial intelligence, 2019.
We present a hierarchical extraction paradigm which approaches relation extraction via hierarchical reinforcement learning
Most existing methods determine relation types only after all the entities have been recognized, thus the interaction between relation types and entity mentions is not fully modeled. This paper presents a novel paradigm to deal with relation extraction by regarding the related entities as the arguments of a relation. We apply a hierarchic...More
