# MiDe22: An Annotated Multi-Event Tweet Dataset for Misinformation Detection

5,284 English tweets with their misinformation labels for several recent events between 2020 and 2022, including the Russia-Ukraine war, COVID-19 pandemic, and Refugees. The dataset also includes user engagements with the tweets in terms of likes, replies, retweets, and quotes. For user engagements please use contact at the end of the dataset card.

## Data Fields
- `tweet`: a `string` feature.
- `label`: a classification label, with possible values including `True`, `False`, `Other`.

## Data Size
|classes|true|false|other|
|-------|---:|----:|----:|
|tweets |727 |1,729|2,828|

## Annotations

Tweets are labeled in terms of three classes: True, False, and Other.
- `True`: tweets with the correct information regarding the corresponding event.
- `False`: tweets with misinformation on the corresponding event.
- `Other`: tweets that cannot be categorized under false or true information.

## Annotation process

This dataset is annotated by five annotators. Each tweet is annotated by at least two annotators, we calculate Krippendorf’s alpha reliability to measure interannotator agreement (IAA). The resulting alpha
coefficient is 0.785. Details are given in [our paper](https://aclanthology.org/2024.lrec-main.986/).
