## Overview
This repo contains the data for CheckThat!Lab 2026 - [Task 1: Source Retrieval for Scientific Web Claims](https://checkthat.gitlab.io/clef2026/task1/)

## Task Definition

Source Retrieval for Scientific Web Claims: Given a social media post that contains a scientific claim and an implicit reference to a scientific paper (mentions it without a URL), retrieve the mentioned paper from a pool of candidate papers.


## Datasets

The collection set contains information about 10k publications. The query sets (train and dev) comprise English, German, and French social media posts.

- **collection_data.json** collection set with 10k publications (columns: pubkey, title, abstract, venue / location, authors) 
- **de_train.json** DE training data (columns: index, pubkey, text)
- **de_dev.json** DE development data (columns: index, pubkey, text)
- **en_train.json** EN training data (columns: index, pubkey, text)
- **en_dev.json** EN development data (columns: index, pubkey, text)
- **fr_train.json** FR training data (columns: index, pubkey, text)
- **fr_dev.json** FR development data (columns: index, pubkey, text)

## Usage
Below is an example for usage:
```python
from datasets import load_dataset

lang = "fr"
split = "train"

data = load_dataset("sschellhammer/CT26_Task1_SourceRetrievalForScientificWebClaims", lang)
split_data = data[split]
labels = np.array(split_data["pubkey"])
```
