  ## 简介 Brief Introduction
  
  善于处理摘要任务，在数个中文摘要数据集上微调后的，中文版的PAGASUS-large。
  
  Good at solving text summarization tasks, after fine-tuning on multiple Chinese text summarization datasets, Chinese PAGASUS-large.

  ## 模型信息 Model Information
  
  参考论文：[PEGASUS: Pre-training with Extracted Gap-sentences for Abstractive Summarization](https://arxiv.org/pdf/1912.08777.pdf)
  
  基于[Randeng-Pegasus-523M-Chinese](https://huggingface.co/IDEA-CCNL/Randeng-Pegasus-523M-Chinese)，我们在收集的7个中文领域的文本摘要数据集（约4M个样本），使用实体过滤后数据集（约1.8M）重新微调，在不损伤下游指标的情况下提升了摘要对原文的忠实度，得到了summary-v1版本。这7个数据集为：education, new2016zh, nlpcc, shence, sohu, thucnews和weibo。
  
  Based on [Randeng-Pegasus-523M-Chinese](https://huggingface.co/IDEA-CCNL/Randeng-Pegasus-523M-Chinese), we fine-tuned a text summarization version (summary-v1) on a filted dataset(1.8M), which we use entitys to filter these 7 Chinese text summarization datasets, with totaling around 4M samples. We can improve the faithfulness of summaries without damage to the downstream task, eg. Rouge-L on lcsts. The datasets include: education, new2016zh, nlpcc, shence, sohu, thucnews and weibo.

  ## 使用 Usage
  
  ```python
  from transformers import PegasusForConditionalGeneration
  # Need to download tokenizers_pegasus.py and other Python script from Fengshenbang-LM github repo in advance,
  # or you can download tokenizers_pegasus.py and data_utils.py in https://huggingface.co/IDEA-CCNL/Randeng_Pegasus_523M/tree/main
  # Strongly recommend you git clone the Fengshenbang-LM repo:
  # 1. git clone https://github.com/IDEA-CCNL/Fengshenbang-LM
  # 2. cd Fengshenbang-LM/fengshen/examples/pegasus/
  # and then you will see the tokenizers_pegasus.py and data_utils.py which are needed by pegasus model
  
  from tokenizers_pegasus import PegasusTokenizer
  
  model = PegasusForConditionalGeneration.from_pretrained("IDEA-CCNL/Randeng-Pegasus-523M-Summary-Chinese-V1")
  tokenizer = PegasusTokenizer.from_pretrained("IDEA-CCNL/Randeng-Pegasus-523M-Summary-Chinese-V1")
  
  text = "在北京冬奥会自由式滑雪女子坡面障碍技巧决赛中，中国选手谷爱凌夺得银牌。祝贺谷爱凌！今天上午，自由式滑雪女子坡面障碍技巧决赛举行。决赛分三轮进行，取选手最佳成绩排名决出奖牌。第一跳，中国选手谷爱凌获得69.90分。在12位选手中排名第三。完成动作后，谷爱凌又扮了个鬼脸，甚是可爱。第二轮中，谷爱凌在道具区第三个障碍处失误，落地时摔倒。获得16.98分。网友：摔倒了也没关系，继续加油！在第二跳失误摔倒的情况下，谷爱凌顶住压力，第三跳稳稳发挥，流畅落地！获得86.23分！此轮比赛，共12位选手参赛，谷爱凌第10位出场。网友：看比赛时我比谷爱凌紧张，加油！"
  inputs = tokenizer(text, max_length=1024, return_tensors="pt")
  
  # Generate Summary
  summary_ids = model.generate(inputs["input_ids"])
  tokenizer.batch_decode(summary_ids, skip_special_tokens=True, clean_up_tokenization_spaces=False)[0]
  
  # model Output: 自由式滑雪女子坡面障碍技巧决赛谷爱凌摘银
