Abstract
“Relation Extraction (RE) task aims to discover the semantic relation that holds between two entitiesand contributes to many applications such as knowledge graph construction and completion. Reinforcement Learning (RL) has been widely used for RE task and achieved SOTA results, whichare mainly designed with rewards to choose the optimal actions during the training procedure,to improve RE’s performance, especially for low-resource conditions. Recent work has shownthat offline or online RL can be flexibly formulated as a sequence understanding problem andsolved via approaches similar to large-scale pre-training language modeling. To strengthen theability for understanding the semantic signals interactions among the given text sequence, thispaper leverages Transformer architecture for RL-based RE methods, and proposes a genericframework called Transformer Enhanced RL (TERL) towards RE task. Unlike prior RL-basedRE approaches that usually fit value functions or compute policy gradients, TERL only outputsthe best actions by utilizing a masked Transformer. Experimental results show that the proposedTERL framework can improve many state-of-the-art RL-based RE methods.”- Anthology ID:
