CFEVER-data

Introduction to CFEVER

This repository contains the dataset for our AAAI 2024 paper, "CFEVER: A Chinese Fact Extraction and VERification Dataset". Paper link.

Leaderboard website

Please visit https://ikmlab.github.io/CFEVER to check the leaderboard of CFEVER.

How to load CFEVER

from datasets import load_dataset

# Get ready data ["train", "dev", "test"]
ds = load_dataset("IKMLab-team/cfever")

# Get separted data by:
train, dev, test = ds["train"], ds["dev"], ds["test"]

# If you only want a part of data
train = load_dataset("IKMLab-team/cfever", name="train")["train"]
# or
train = load_dataset("IKMLab-team/cfever", split="train")

# wiki page data:
wiki_pages = load_dataset("IKMLab-team/cfever", name="wiki_pages")["plain"]

Evaluation

• Please refer to our codebase: https://github.com/IKMLab/CFEVER-baselines/?tab=readme-ov-file#evaluations

Submission

• Please include three fields (necessary) in the prediction file for each claim in the test set.
  • id
  • predicted_label
  • predicted_evidence
• The id field has been already included in the test set. Please do not change the order.
• The predicted_label should be one of supports, refutes, or NOT ENOUGH INFO.
• The predicted_evidence should be a list of evidence sentences, where each evidence sentence is represented by a list of [page_id, line_number]. For example:

# One evidence sentence for the claim
{
    "id": 1,
    "predicted_label": "REFUTES",
    "predicted_evidence": [
        ["page_id_2", 2],
    ]
}

# Two evidence sentences for the claim
{
    "id": 1,
    "predicted_label": "SUPPORTS",
    "predicted_evidence": [
        ["page_id_1", 1],
        ["page_id_2", 2],
    ]
}

# The claim cannot be verified
{
    "id": 1,
    "predicted_label": "NOT ENOUGH INFO",
    "predicted_evidence": None
}

• After creating the prediction file, please email the file to yingjia.lin.public@gmail.com with a brief description of your method. We will evaluate your submission and update the leaderboard.
• A randomly generated submission file can be found here.
  • Note that claim is not necessary to be included in the submission file.
• You can also check the prediction example for the development set and follow the evaluation steps from our CFEVER-baselines repo.
