The Big Bad NLP Database (BBNLPDB) was introduced in 2020 as a free, searchable and sortable directory for finding natural language processing datasets. KDnuggets described it then as containing nearly 300 datasets. That figure and the directory’s availability are historical: its current status and inventory have not been confirmed.
What was the Big Bad NLP Database?
BBNLPDB was a centralized directory intended to make it easier to find accessible, relevant datasets for NLP learning and task work. In a February 28, 2020 article, KDnuggets Managing Editor Matthew Mayo described it as a collection curated from around the internet and wrote: “BBNLPDB provides access to nearly 300 well-organized, sortable, and searchable natural language processing datasets.” Read the KDnuggets announcement.
The directory was presented as a way to discover datasets, not as a dataset itself or as a guarantee that any listed resource would fit every project.
What kinds of NLP datasets did it cover?
The 2020 announcement named a range of task areas. Its examples included:

- Document classification and intent classification
- Question answering
- Automated image captioning
- Dialog
- Clustering
- Language modeling
- Machine translation
- Text corpora
These are categories cited in the original announcement, not a verified description of the directory’s current catalogue. The article did not provide counts by task.
Which languages were represented?
The announcement described the collection as English-heavy and also mentioned datasets in Arabic, Chinese, German, Dutch, Indian languages, and multiple languages. It did not give a language-by-language count, so the relative coverage beyond the English-heavy characterization is unclear. The list should be read as a historical overview, not a confirmed current language inventory.

How could learners and practitioners use the directory?
KDnuggets presented the collection as useful for practicing NLP skills and benchmarking against standard datasets. A directory can simplify discovery, but selecting a dataset still requires checking whether it suits the work at hand.
Check the task match
Start with the task you need to study or evaluate—such as text classification, question answering, or machine translation—and confirm that the dataset actually measures that task. A broad label alone may not capture the details of your intended problem.
Rank #3
Check language coverage
Confirm that the dataset’s language matches your project. The announcement’s general note about language availability does not establish which languages are present in any particular dataset.
Check whether it represents your intended use
The original article cautioned that convenient, well-organized datasets do not necessarily represent real-world data. A standard dataset may be useful for a repeatable benchmark, but that alone does not show that results will transfer to a different population, domain, or deployment setting. Treat benchmark performance and evidence of real-world fitness as separate questions.
Rank #4
Is BBNLPDB still available?
Its current operating status, maintenance, and contents are unconfirmed. The official directory link, datasets.quantumstat.com, timed out when checked for this article, so it is not possible to verify that the directory remains online or that its contents match the 2020 description. KDnuggets’ “nearly 300” figure refers to its February 2020 announcement and should not be treated as a current count.
