+# Uses
+ 
+
+## Direct Use
+The model authors also note in the [GitHub Repo](https://github.com/basketballandlearn/MRC_Competition_Dureader)
+> 此mrc模型可直接用于open domain，点击体验
+ 
+## Downstream Use [Optional]
+ 
+The model authors also note in the [GitHub Repo](https://github.com/basketballandlearn/MRC_Competition_Dureader)
+> 将此模型放到下游 MRC/分类 任务微调可比直接使用预训练语言模型提高2个点/1个点以上
+ 
+## Out-of-Scope Use
+ 
+The model should not be used to intentionally create hostile or alienating environments for people. 
+ 
+# Bias, Risks, and Limitations
+ 
+ 
+Significant research has explored bias and fairness issues with language models (see, e.g., [Sheng et al. (2021)](https://aclanthology.org/2021.acl-long.330.pdf) and [Bender et al. (2021)](https://dl.acm.org/doi/pdf/10.1145/3442188.3445922)). Predictions generated by the model may include disturbing and harmful stereotypes across protected classes; identity characteristics; and sensitive, social, and occupational groups.
+
+
+
+## Recommendations
+ 
+ 
+Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. More information needed for further recommendations.
+
+
+# Training Details
+ 
+## Training Data
+ 
+The model authors also note in the [GitHub Repo](https://github.com/basketballandlearn/MRC_Competition_Dureader)
+> 网上收集的大量中文MRC数据 （其中包括公开的MRC数据集以及自己爬取的网页数据等， 囊括了医疗、教育、娱乐、百科、军事、法律、等领域。）
+ 
+## Training Procedure
+
+ 
+### Preprocessing
+The model authors also note in the [GitHub Repo](https://github.com/basketballandlearn/MRC_Competition_Dureader): 
+>**清洗**
+舍弃：context>1024的舍弃、question>64的舍弃、网页标签占比超过30%的舍弃。
+重新标注：若answer>64且不完全出现在文档中，则采用模糊匹配: 计算所有片段与answer的相似度(F1值)，取相似度最高的且高于阈值（0.8）
+**数据标注**
+收集的数据有一部分是不包含的位置标签的，仅仅是(问题-文章-答案)的三元组形式。 所以，对于只有答案而没有位置标签的数据通过正则匹配进行位置标注：
+ 若答案片段多次出现在文章中，选择上下文与问题最相似的答案片段作为标准答案（使用F1值计算相似度，答案片段的上文48和下文48个字符作为上下文）；
+ 若答案片段只出现一次，则默认该答案为标准答案。
+采用滑动窗口将长文档切分为多个重叠的子文档，故一个文档可能会生成多个有答案的子文档。
+**无答案数据构造**
+     在跨领域数据上训练可以增加数据的领域多样性，进而提高模型的泛化能力，而负样本的引入恰好能使得模型编码尽可能多的数据，加强模型对难样本的识别能力：
+1.)  对于每一个问题，随机从数据中捞取context，并保留对应的title作为负样本;（50%）
+2.)  对于每一个问题，将其正样本中答案出现的句子删除，以此作为负样本；（20%）
+3.)  对于每一个问题，使用BM25算法召回得分最高的前十个文档，然后根据得分采样出一个context作为负样本， 对于非实体类答案，剔除得分最高的context（30%）
