run pip install -r requirements.txt to install the required packages.

Train QG Models

1. Prepare data

   You can use the hotpotQA dataset ./data/hotpotqa and squad1.1 dataset ./data/squad1.1 we provided, or use your own dataset which provides passages, references, and answers.

   If you use the datasets we provided, run python process.py to process the data, ready for your training.

   # For example: train T5 based on HotpotQA
   save_dir = 'directory to save processed data'
   hot = T5Hotpot()
   hot.deal_hotpot(save_dir)
   

2. Train your own QG models

   We provide codes to train T5/FLAN-T5/BART-based QG models. You may update training arguments in ./args, and run the code file for specific model to train.

   # model name: code file name
   BART-base/large_finetune: bart.py
   T5-base/large_finetune: T5.py
   Flan-T5-base/large_finetune: Flan-T5.py
   Flan-T5-xl/xxl_LoRA: Flan-T5-lora.py
   

   For example, train T5-base_finetune QG model based on HotpotQA

   • Update the arg_file ./args/t5_base_hotpot.json

     {
         "model_name_or_path": "google-t5/t5-base",
         "tokenizer_name_or_path": "google-t5/t5-base",
         "max_len": 512,
         "target_max_len": 163,
         "output_dir": "./model/t5-base/hotpotqa",
         "overwrite_output_dir": true,
         "per_device_train_batch_size": 16,
         "per_device_eval_batch_size": 16,
         "gradient_accumulation_steps": 8,
         "learning_rate": 0.0001,
         "warmup_steps": 500,
         "weight_decay": 0.01,
         "num_train_epochs": 10,
         "seed": 42,
         "do_train": true,
         "do_eval": true,
         "logging_steps": 100,
         "logging_dir": "./model/t5-base/logs",
         "train_file_path": "./data/data_t5/hotpotqa/pt/train.pt",
         "valid_file_path": "./data/data_t5/hotpotqa/pt/dev.pt",
         "remove_unused_columns": false,
         "prediction_loss_only": true,
         "load_best_model_at_end": true,
         "evaluation_strategy": "epoch",
         "save_strategy": "epoch"
     }
     

   • Run code in T5.py to train QG model

     # train model
     arg_path = './args/t5_base_hotpot.json'
     data_dir = 'directory of your data'    # processed data
     train_path = data_dir + 'train.json'
     dev_path = data_dir + 'dev.json'
     test_path = data_dir + 'test.json'   # optional
     train_qg(arg_path, train_path, dev_path, test_path)
     

Generate questions using QG models

We provide different types of QG models for question generation.

1. Use fine-tuned models in lmqg

   run python apply_lmqg.py to get the questions generated by models in lmqg.

   model_name = 'lmqg/flan-t5-base-squad-qg'
   data_json_path='./data/squad-test.json'
   save_path='./result/squad-test.csv'
   questions = apply_lmqg(
       model_name=model_name,
       data_json_path=data_json_path,
       save_path=save_path,
       batch_size=8
   )
   

2. Use fine-tuned (including LoRA) models we provided for QG

   Run specific code file for each type of model. For example, to use T5-base_finetune model to generate questions on HotpotQA Test Set, run code in T5.py.

   # test
   arg_path = './args/t5_base_hotpot.json'
   test_pt_path = './data/data_t5/hotpotqa/pt/test.pt'    # tokenized test data
   model_dir = './model/t5-base/hotpotqa/'
   tokenizer_dir = model_dir + 'tokenizer/'
   result_save_path = './result/t5-base-finetune/hotpotqa/prediction.csv'
   decoded_texts = predict(model_dir, tokenizer_dir, test_pt_path, result_save_path)
   

3. Use few-shot mode

   Run specific code file for each type of model. For example, to use Flan-T5-xl_fewshot model to generate questions on HotpotQA Test Set, run code in Flan-T5.py.

   # few-shot prediction
   model = 'google/flan-t5-large'
   few_shot_path = './data/squad1.1-few.json' # examples used for few-shot learning
   test_path = './data/squad-dev.json'
   result_save_path = './result/{}/prediction-few.csv'.format(model)
   dataset_name = 'hotpotqa'
   predict_few(model, few_shot_path, test_path, result_save_path, dataset_name)
   

4. Use GPTs

   Run code in generate_gpt.py

   data_path = './test.xlsx'    # your data for QG
   model = 'gpt-3.5-turbo'
   save_dir = './result/'
   few_shot_path = './data/hotpotqa-few.json'
   question_generation(
       data_path=data_path,
       model=model,
       save_dir=save_dir,
       few_shot_path=few_shot_path
   )
