# Dataset Card for "tner/tweetner7"

## Dataset Description

- **Repository:** [https://github.com/asahi417/tner/tree/master/examples/tweetner7_paper](https://github.com/asahi417/tner/tree/master/examples/tweetner7_paper)
- **Paper:** [https://arxiv.org/abs/2210.03797](https://arxiv.org/abs/2210.03797)
- **Dataset:** TweetNER7
- **Domain:** Twitter
- **Number of Entity:** 7


### Dataset Summary
This is the official repository of TweetNER7 (["Named Entity Recognition in Twitter:
A Dataset and Analysis on Short-Term Temporal Shifts, AACL main conference 2022"](https://arxiv.org/abs/2210.03797)), an NER dataset on Twitter with 7 entity labels. Each instance of TweetNER7 comes with a timestamp which distributes from September 2019 to August 2021.
The tweet collection used in TweetNER7 is same as what used in [TweetTopic](https://huggingface.co/datasets/cardiffnlp/tweet_topic_multi).
The dataset is integrated in [TweetNLP](https://tweetnlp.org/) too.
- Entity Types: `corperation`, `creative_work`, `event`, `group`, `location`, `product`, `person` 

### Preprocessing
We pre-process tweets before the annotation to normalize some artifacts, converting URLs into a special token `{{URL}}` and non-verified usernames into `{{USERNAME}}`.
For verified usernames, we replace its display name (or account name) with symbols `{@}`.
For example, a tweet

```
Get the all-analog Classic Vinyl Edition
of "Takin' Off" Album from @herbiehancock
via @bluenoterecords link below: 
http://bluenote.lnk.to/AlbumOfTheWeek
```

is transformed into the following text.
```
Get the all-analog Classic Vinyl Edition
of "Takin' Off" Album from {@herbiehancock@}
via {@bluenoterecords@} link below: {{URL}}
```

A simple function to format tweet follows below.

```python
import re
from urlextract import URLExtract
extractor = URLExtract()

def format_tweet(tweet):
    # mask web urls
    urls = extractor.find_urls(tweet)
    for url in urls:
        tweet = tweet.replace(url, "{{URL}}")
    # format twitter account
    tweet = re.sub(r"\b(\s*)(@[\S]+)\b", r'\1{\2@}', tweet)
    return tweet

target = """Get the all-analog Classic Vinyl Edition of "Takin' Off" Album from @herbiehancock via @bluenoterecords link below: http://bluenote.lnk.to/AlbumOfTheWeek"""
target_format = format_tweet(target)
print(target_format)
'Get the all-analog Classic Vinyl Edition of "Takin\' Off" Album from {@herbiehancock@} via {@bluenoterecords@} link below: {{URL}}'
```


We ask annotators to ignore those special tokens but label the verified users' mentions.


### Data Split

| split             | number of instances | description |
|:------------------|------:|------:|
| train_2020        |  4616 | training dataset from September 2019 to August 2020 |
| train_2021        |  2495 | training dataset from September 2020 to August 2021 |
| train_all         |  7111 | combined training dataset of `train_2020` and `train_2021` |
| validation_2020   |   576 | validation dataset from September 2019 to August 2020 |
| validation_2021   |   310 | validation dataset from September 2020 to August 2021 | 
| test_2020         |   576 | test dataset from September 2019 to August 2020 |
| test_2021         |  2807 | test dataset from September 2020 to August 2021 |
| train_random      |  4616 | randomly sampled training dataset with the same size as `train_2020` from `train_all` |
| validation_random |   576 | randomly sampled training dataset with the same size as `validation_2020` from `validation_all` |
| extra_2020        | 87880 | extra tweet without annotations from September 2019 to August 2020 |
| extra_2021        | 93594 | extra tweet without annotations from September 2020 to August 2021 |

For the temporal-shift setting, model should be trained on `train_2020` with `validation_2020` and evaluate on `test_2021`.
In general, model would be trained on `train_all`, the most representative training set with `validation_2021` and evaluate on `test_2021`.

## Dataset Structure

### Data Instances
An example of `train` looks as follows.
