StructBERT: Incorporating Language Structures into Pre-training for Deep Language Understanding

Introduction

We extend BERT to a new model, StructBERT, by incorporating language structures into pre-training. Specifically, we pre-train StructBERT with two auxiliary tasks to make the most of the sequential order of words and sentences, which leverage language structures at the word and sentence levels, respectively.
