Pylon

This repo includes the codebase and data of paper Pylon: Semantic Table Union Search in Data Lakes.

Environment Setup

conda env create -f pylon_environment.yml

Models & Data

Model checkpoints are available at our Google Drive.

pylon_benchmark.tar.gz contains the benchmark we created from a real-world corpus (GitTables) for semantic table union search.

Evaluation

To run the evaluation, follow the steps below:

1. cd wte_cl
2. Change paths as appropriate in bash scripts under scripts/
3. Run, for example, the evaluation on the Pylon benchmark ./scripts/run_wte_cl_pylon.sh

Pre-training

To pre-train an embedding model, follow the steps below:

1. cd wte_cl/wte_cl_training
2. Change paths and hyperparameters as appropriate in train_model.py
3. python train_model.py

TLDR: One paper with the same idea as ours is published in VLDB 2023. The first author, she was a friend.
