### Dataset Summary

ComQA is a dataset of 11,214 questions, which were collected from WikiAnswers, a community question answering website.
By collecting questions from such a site we ensure that the information needs are ones of interest to actual users.
Moreover, questions posed there are often cannot be answered by commercial search engines or QA technology, making them
more interesting for driving future research compared to those collected from an engine's query log. The dataset contains
questions with various challenging phenomena such as the need for temporal reasoning, comparison (e.g., comparatives,
superlatives, ordinals), compositionality (multiple, possibly nested, subquestions with multiple entities), and
unanswerable questions (e.g., Who was the first human being on Mars?). Through a large crowdsourcing effort, questions
in ComQA are grouped into 4,834 paraphrase clusters that express the same information need. Each cluster is annotated
with its answer(s). ComQA answers come in the form of Wikipedia entities wherever possible. Wherever the answers are
temporal or measurable quantities, TIMEX3 and the International System of Units (SI) are used for normalization.

## Dataset Structure

We show detailed information for up to 5 configurations of the dataset.

### Data Instances

#### default

- **Size of downloaded dataset files:** 1.59 MB
- **Size of the generated dataset:** 1.05 MB
- **Total amount of disk used:** 2.65 MB

An example of 'validation' looks as follows.
```
{
    "answers": ["https://en.wikipedia.org/wiki/north_sea"],
    "cluster_id": "cluster-922",
    "questions": ["what sea separates the scandinavia peninsula from britain?", "which sea separates britain from scandinavia?"]
}
```

### Data Fields

The data fields are the same among all splits.

#### default
- `cluster_id`: a `string` feature.
- `questions`: a `list` of `string` features.
- `answers`: a `list` of `string` features.

### Data Splits Sample Size
