# Dataset Card for TweetQA

## Dataset Structure

### Data Instances

Sample data:

{
"Question": "who is the tallest host?",
"Tweet": "Don't believe @ConanOBrien's height lies. Sam Bee is the tallest host in late night. #alternativefacts\u2014 Full Frontal (@FullFrontalSamB) January 22, 2017",
"qid": "3554ee17d86b678be34c4dc2c04e334f"
}

### Data Fields

Question: a question based on information from a tweet Answer: list of possible answers from the tweet Tweet: source tweet qid: question id

### Data Splits

The dataset is split in train, validation and test. The test split doesn't include answers so the Answer field is an empty list.

## Dataset Creation

### Curation Rationale

With social media becoming increasingly popular on which lots of news and real-time events are reported, developing automated question answering systems is critical to the effectiveness of many applications that rely on realtime knowledge. While previous datasets have concentrated on question answering (QA) for formal text like news and Wikipedia, we present the first large-scale dataset for QA over social media data. To ensure that the tweets we collected are useful, we only gather tweets used by journalists to write news articles. We then ask human annotators to write questions and answers upon these tweets. Unlike other QA datasets like SQuAD in which the answers are extractive, we allow the answers to be abstractive

### Source Data

#### Initial Data Collection and Normalization

We first describe the three-step data collection process of TWEETQA: tweet crawling, question-answer writing and answer validation. Next, we define the specific task of TWEETQA and discuss several evaluation metrics. To better understand the characteristics of the TWEETQA task, we also include our analysis on the answer and question characteristics using a subset of QA pairs from the development set.
