📄 [RAG over Tables: Hierarchical Memory Index, Multi-Stage Retrieval, and Benchmarking](https://arxiv.org/abs/2504.01346) | 👨🏻‍💻 [Code](https://github.com/jiaruzouu/T-RAG) | 🤗 [MultiTableQA Hub Collection](https://huggingface.co/collections/jiaruz2/multitableqa-68dc8d850ea7e168f47cecd8)

This repository contains **MultiTableQA-TabFact**, one of the five datasets released as part of the comprehensive **MultiTableQA** benchmark. MultiTableQA-TabFact focuses on **table fact-checking** tasks. The overall MultiTableQA benchmark extends the traditional single-table QA setting into a multi-table retrieval and question answering benchmark, enabling more realistic and challenging evaluations.

Other datasets in the MultiTableQA benchmark include:

### Sample Usage

To download and preprocess the **MultiTableQA** benchmark, navigate to the `table2graph` directory in the code repository and run the `prepare_data.sh` script:

```bash
cd table2graph
bash scripts/prepare_data.sh
```

This script will automatically fetch the source tables, apply decomposition (row/column splitting), and generate the benchmark splits.
