Review of Relation Extraction Based on Pre-training Language Model

In recent years, with the continuous innovation of deep learning technology， the application of pre-training models in natural language processing has become more and more extensive, and relation extraction is no longer purely dependent on the traditional pipeline method. The development of pre-training language models has greatly promoted the related research of relation extraction， and has surpassed traditional methods in many fields. First， this paper briefly introduces the development of relationship extraction and classic pre-training models；secondly, summarizes the current commonly used data sets and evaluation methods, and analyzes the performance of the model on each data set; finally， discusses the development challenges of relationship extraction and future research trends.
