Preprocess two datasets TianGong-SS-FSD and TianGong-Qref into the the following format:

[Reformulation Type]<tab>[Click List]<tab>[Usefulness List]<tab>[Satisfaction Label]

• Reformulation Type: A (Add), D (Delete), K (Keep), T (Transform or Change), O (Others), F (First Query).
• Click List: 1 -- Clicked, 0 -- Not Clicked.
• Usefulness List: Usefulness or Relevance, 4-scale in TianGong-QRef, 5-scale in TianGong-SS-FSD.
• Satisfaction Label: 5-scale for both datasets.

Then, bootsrap them into N samples and put the bootstapped data (directories) into ./data/bootstrap_fsd and ./data/bootstrap_qref.

The results for each metrics are shown in the following table:

To reproduce the results of traditional metrics such as RBP, DCG and BPM, we recommend you to use this repo: cwl_eval. 🤗

To train RAMs, run the script as follows:

python run.py --click_model DBN \
	--data qref --id 0 \
	--metric_type expected_utility \
	--max_usefulness 3 \
	--k_num 6 \
	--max_dnum 10 \
	--iter_num 10000 \
	--alpha 0.01 \
	--alpha_decay 0.99 \
	--lamda 0.85 \
	--patience 5 \
	--use_knowledge

• click_model: options: ['DBN', 'SDBN', 'UBM', 'PBM']
• data: options: ['fsd', 'qref']
• metric_type: options: ['expected_utility', 'effort']
• id: the bootstrapped sample id.
• k_num: the number of user intent shift type will be considered, should be less than or equal to six.
• max_dnum: the maximum number of top documents to be considered for a specific query.
• use_knowledge: whether to use the transition probability from syntactic reformulation types to intent-level ones derived from the TianGong-Qref dataset.
