This is the source code for our paper Leveraging Adjective-Noun Phrasing Knowledge for Comparison Relation Prediction in Text-to-SQL (EMNLP 2019).

In this paper, we propose to leverage adjective-noun phrasing knowledge mined from the web to predict the comparison relations in text-to-SQL. Experimental results on both the original and the re-split Spider dataset show that our approach achieves significant improvement over syntaxSQL and SQLNet on comparison relation prediction.

1. The baseline codes use Python 2.7 and Pytorch 0.2.0 GPU. Install Python dependency: pip install -r requirements.txt Alternatively use docker: docker pull buaa1156/py27torch0.2cuda8vim:latest
2. The preprocess scripts use Python >= 3.5.

1. The dataset comes from the Spider task website, and the singletable and resplitdata used in our paper are under data/singletable and data/resplitdata respectively.
2. The knowledge used in this paper is under the folder data/knowledge.
3. Download the pretrained Glove, and put it under syntaxSQL and SQLNet folders as glove/glove.42B.300d.txt
4. Download evaluation.py and process_sql.py from the Spider github page, and evaluate the results following their instructions.

1. Generated train and dev data by running:
   • python3 preprocess_syntaxSQL.py train|dev singletable|resplitdata
2. Preprocess knowledge features by running:
   • python3 preprocess_direction_features.py syntaxSQL singletable|resplitdata weighted|direct
3. Run run_train.sh and run_test.sh under the directory syntaxSQL after setting the data_type, feats_format, and DATE at first lines.
   • data_type: singletable or resplitdata
   • feats_format: weighted or direct
   • DATE: automatically set as local time while training and manually assigned while testing

1. Copy files in data/ directory to SQLNet/data/
2. Preprocess knowledge features by running:
   • python3 preprocess_direction_features.py SQLNet singletable|resplitdata weighted|direct
3. Run run_train.sh and run_test.sh under the directory SQLNet after setting the data_type, feats_format, and DATE at first lines.
   • data_type: singletable or resplitdata
   • feats_format: weighted or direct
   • DATE: automatically set as local time while training and manually assigned while testing
