# Dataset Card for FreshStack (Corpus)

[Homepage](https://fresh-stack.github.io) | 
[Repository](https://github.com/fresh-stack/freshstack) |
[Paper](https://arxiv.org/abs/2504.13128)

FreshStack is a holistic framework to construct challenging IR/RAG evaluation datasets that focuses on search across niche and recent topics.

This dataset (October 2024) contains the query, nuggets, answers and nugget-level relevance judgments of 5 niche topics focused on software engineering and machine learning. 

The queries and answers (accepted) are taken from Stack Overflow, GPT-4o generates the nuggets and labels the relevance between each nugget and a given document list.

This repository contains the corpus of GitHub chunked documents of five niche topics in freshstack. The queries, answers and nuggets can be found [here](https://huggingface.co/datasets/freshstack/queries-oct-2024).

## Dataset Structure

To access the data using HuggingFace `datasets`:
```
topic='langchain'  # or any of the 5 topics
freshstack = datasets.load_dataset('freshstack/corpus-oct-2024', topic)

# train set
for data in freshstack['train']:
  doc_id = data['_id']
  doc_text = data['text'] 
```

## Dataset Statistics 
The following table contains the number of documents (`#D`) and the number of GitHub repositories used (`#G`) in the FreshStack collection.

| Topic | Versions | Domain | Train |        |
|:----:|:-----:|:-----:|:-----:|:------:|
|            |     |     | **#D**| **#G** |
|  langchain | -   |Machine Learning     | 49,514  | 10 |
|  yolo      | v7 & v8 | Computer Vision      | 27,207  | 5  |
|  laravel   | 10 & 11 | Back-end Development | 52,351  | 9  |
|  angular   | 16, 17 & 18 | Front-end Development| 117,288 | 4  |
|  godot     | 4 | Game Development     | 25,482  | 6  |
