rebel-base-chinese-cndbpedia is a generation-based relation extraction model

  ·a SOTA chinese end-to-end relation extraction model,using bart as backbone.
  
  ·using the training method of <REBEL：Relation Extraction By End-to-end Language generation>(EMNLP Findings 2021).
  
  ·using the Distant-supervised data from cndbpedia,pretrained from the checkpoint of fnlp/bart-base-chinese.
  
  ·can perform SOTA in many chinese relation extraction dataset,such as lic2019,lic2020,HacRED,etc.
  
  ·easy to use,just like normal generation task.
  
  ·input is sentence,and output is linearlize triples,such as input:姚明是一名NBA篮球运动员 output:[subj]姚明[obj]NBA[rel]公司[obj]篮球运动员[rel]职业(more details can read on REBEL paper)
