# HousingQA (MTEB format)
This is the version of the [HousingQA](https://huggingface.co/datasets/reglab/housing_qa) evaluation dataset formatted in the [Massive Text Embedding Benchmark (MTEB)](https://github.com/embeddings-benchmark/mteb) information retrieval dataset format.

This dataset tests the ability of information retrieval models to retrieve relevant legislation to complex, reasoning-intensive legal questions.

## Structure 🗂️
As per the MTEB information retrieval dataset format, this dataset comprises three splits, `default`, `corpus`, and `queries`.

The `default` split pairs questions (`query-id`) with relevant legislation (`corpus-id`), each pair having a `score` of 1.

The `corpus` split contains legislation, with the text of a law being stored in the `text` key and its id being stored in the `_id` key. There is also a `title` column, which is deliberately set to an empty string in all cases for compatibility with the [`mteb`](https://github.com/embeddings-benchmark/mteb) library.

The `queries` split contains questions, with the text of a question being stored in the `text` key and its id being stored in the `_id` key.

## Methodology 🧪
To understand how HousingQA itself was created, refer to its [documentation](https://huggingface.co/datasets/reglab/housing_qa).

This dataset was formatted by taking the test split of HousingQA and treating questions as anchors and relevant legislation as positive passages. 500 examples were randomly sampled in order to keep the size of this dataset manageable.
