This is the official code for the Microsoft's submission of SDNet model to CoQA leaderboard. It is implemented under PyTorch framework. The related paper to cite is:
SDNet: Contextualized Attention-based Deep Network for Conversational Question Answering, by Chenguang Zhu, Michael Zeng and Xuedong Huang, at https://arxiv.org/abs/1812.03593.
For usage of this code, please follow Microsoft Open Source Code of Conduct.
main.py: the starter code
Requirement: PyTorch 0.4.1, spaCy 2.0.16. The docker we used is available at dockerhub: https://hub.docker.com/r/zcgzcgzcg/squadv2/tags. Please use v3.0 or v4.0. 1. Create a folder (e.g. coqa) to contain data and running logs; 2. Create folder coqa/data to store CoQA raw data: coqa-train-v1.0.json and coqa-dev-v1.0.json; 3. Copy the file conf from the repo into folder coqa; 4. If you want to use BERT-Large, download their model into coqa/bert-large-uncased; if you want to use BERT-base, download their model into coqa/bert-base-cased; * The models can be downloaded from Huggingface: * 'bert-base-uncased': "https://s3.amazonaws.com/models.huggingface.co/bert/bert-base-uncased.tar.gz", * 'bert-large-uncased': "https://s3.amazonaws.com/models.huggingface.co/bert/bert-large-uncased.tar.gz" * bert-large-uncased-vocab.txt can be downloaded from Google's BERT repository 5. Create a folder glove in the same directory of coqa and download GloVe embedding glove.840B.300d.txt into the folder.
Your directory should look like this:
* glove/ * glove.840B.300d.txt
python main.py train path_to_coqa/conf.
If you run for the first time, CoQAPreprocess.py will automatically create folders conf~/spacyintermediatefeatures~ inside coqa to store intermediate tokenization results, which will take a few hours.
Every time you run the code, a new running folder run_idx will be created inside coqa/conf~, which contains running logs, prediction result on dev set, and best model.
