[0069] The invention discloses a machine reading comprehension method based on iterative screening and pre-training enhancement. The method is applied to the need to adopt automatic means to improve the question and answer effect and improve the user's search or language question and answer experience.
[0070] like figure 1 As shown, the present invention provides a machine reading comprehension method based on iterative screening and pre-training enhancement, comprising the following steps:
[0071] Step 1. Use the HotpotQA dataset (References: Zhilin Yang, Peng Qi, Saizheng Zhang, Yoshua Bengio, William Cohen, Ruslan Salakhutdinov and Christopher D. Manning. HotpotQA: A dataset for diverse, explainable multi-hop questionanswering [C]. In EMNLP, 2018) Training the relevant document model, using whether it is a supporting document as a label and using equal sampling to obtain training positive and negative samples;
[0072] Step 2, use the pre-trained model to fine-tune the ...
