    Multi-choice Machine Reading Comprehension

    2021.03 - 2021.04

    Converting the multi-choice machine reading comprehension task into a multi-classification problem, mainly considers the use of pre-trained language models, data enhancement, back translation, adversarial training, and model fusion to improve the effect of the model and improve the accuracy of the model.

    GIT

    Bi-directional Cognitive Thinking Network

    2020.02 - 2020.06

    Inspired by the cognitive complementary learning system, the reverse thinking network is proposed, which considers the inverse relationship between the passages and the answers, so that the machine can learn to take the initiative to ask questions, and decouple the two-way knowledge, to assist the answer generation.

    GIT

    MRC method based on Multi-step Reasoning

    2019.07 - 2020.01

    The evidence extraction module is designed for unanswerable questions in DuReader and SQuAD 2.0, and the key evidence are extracted by multi-step reasoning, which adaptively determines whether the question is answerable or not, with an improvement of 2.2% in rouge-L and 1.8% in F1 compared to the two datasets, respectively.

    GIT

    2018.10 - 2019.01

    Classification based on hierarchical Attention    
  • Combined with the GRU neural network and the Attention mechanism, considering the hierarchical structure between words, sentences and documents, the hierarchical Attention is introduced to capture word order and semantic information to a certain extent, and trained on a subset of the Tsinghua THUCNews dataset, the accuracy rate is 91.95 % increased to 93.75%.

    • 2017.12 - 2018.04

    Named Entity Recognition(NER) based on CRF+LSTM    
  • When the LSTM neural network performs NER, it only considers the local optimum, and the effect is poor, and CRF has the problem of feature engineering. Combined with the method of automatic feature extraction by neural network and global normalization of conditional random field. In the Chinese NER task, the model is improved by 4.65%, 5.34% and 5.78% compared with the CRF on person, location and recognition.
