We provide Quasar-T, SearchQA and TrivialQA dataset we used for the task in data/ directory. We preprocess the original data to make it satisfy the input format of our codes, and can be download at here.
To run our code, the dataset should be put in the folder data/ using the following format:
datasets/
-
train.txt, dev.txt, test.txt: format for each line: {"question": quetion, "answers":[answer1, answer2, ...]}.
-
train.json, dev.json, test.json: format [{"question": question, "document":document1},{"question": question, "document":document2}, ...].
embeddings/
- glove.840B.300d.txt: word vectors obtained from here.
corenlp/
- all jar files from Stanford Corenlp.
The source codes of our models are put in the folders src/.
For training and test, you need to:
-
Pre-train the paragraph reader: python main.py --batch-size 256 --model-name quasart_reader --num-epochs 10 --dataset quasart --mode reader
-
Pre-train the paragraph selector: python main.py --batch-size 64 --model-name quasart_selector --num-epochs 10 --dataset quasart --mode selector --pretrained models/quasart_reader.mdl
-
Train the whole model: python main.py --batch-size 32 --model-name quasart_all --num-epochs 10 --dataset quasart --mode all --pretrained models/quasart_selector.mdl
