Dataset Card for Bernice Pre-train Data

Dataset Summary

Tweet IDs for the 2.5 billion multilingual tweets used to train Bernice, a Twitter encoder. Read the paper here. The tweets are from the public 1% Twitter API stream from January 2016 to December 2021. Twitter-provided language metadata is provided with the tweet ID. The data contains 66 unique languages, as identified by ISO 639 language codes, including und for undefined languages. Tweets need to be re-gathered via the Twitter API. We suggest Hydrator or tweepy.

To load with HuggingFace:

from datasets import load_dataset
dataset = load_dataset("jhu-clsp/bernice-pretrain-data")

for i, row in enumerate(dataset["train"]):
    print(row)
    if i > 10:
        break

If you only want Indic languages, use

dataset = load_dataset("jhu-clsp/bernice-pretrain-data", "indic")

Dataset Creation

Curation Rationale

Data was gathered to support the training of Bernice, a multilingual pre-trained Twitter encoder.

Source Data

Initial Data Collection and Normalization

Data was gathered via the Twitter API public 1% stream from January 2016 through December 2021. Tweets with less than three non-username or URL space-delimited words were removed. All usernames and URLs were replaced with @USER and HTTPURL, respectively.

Who are the source language producers?

Data was produced by users on Twitter.

Annotations

N/A

Personal and Sensitive Information

As per Twitter guidelines, only tweet IDs and not full tweets are shared. Tweets will only be accessible if user has not removed their account (or been banned), tweets were deleted or removed, or a user changed their account access to private.
