> **Raw CommonCrawl crawls, annotated with Creative Commons license information** |
|
|
|
|
|
This dataset is an effort to collect Creative Commons-licensed web data in one place. |
|
|
|
|
|
The licensing information is extracted from the web pages based on whether they link to Creative Commons licenses either overtly in `a` tags (like in the footer of Wikipedia) or in metadata fields indicating deliberate Creative Commons publication. **However, false positives may occur!** While further filtering based on the location type of the license should improve the precision (e.g. by removing hyperlink (a_tag) references), false positives may still occur. **See Recommendations and Caveats below!** Also see [Personal and Sensitive Information](#personal-and-sensitive-information). |
|
|
|
|
|
## Code |
|
|
|
|
|
I am very grateful to the Flemish Supercomputer to provide compute necessary to create this dataset, but as you can tell there is still a lot of data left to be processed. Therefore, I am happy to collaborate to process as many Common Crawl crawls as possible. [Shoot me a message](mailto:bram.vanroy@kuleuven.be) if you want to sponsor this project with compute! You can also simply run the code yourself if you'd like. You can find the whole code base, based on `datatrove`, on [Github](https://github.com/BramVanroy/CommonCrawl-CreativeCommons). If you use the code, please [reference my work](https://github.com/BramVanroy/CommonCrawl-CreativeCommons?tab=readme-ov-file#citation) accordingly and share your processed crawls with the rest of the world (or get in touch with me so I can add them to this repo). |
|
|
|
|
|
## Usage |
|
|
|
|
|
```python |
|
|
from datasets import load_dataset |
|
|
|
|
|
# Everything, most recent -- massive, you will need streaming |
|
|
ds = load_dataset("BramVanroy/CommonCrawl-CreativeCommons", streaming=True) |
|
|
|
|
|
# v1 (2019-30, 2020-05, 2022-05, 2023-06, 2024-51, 2025-05, 2024-46) |
|
|
ds = load_dataset("BramVanroy/CommonCrawl-CreativeCommons", "v1", streaming=True) |
|
|
|
|
|
# Single dump, all languages -- large, you may need streaming on non-server hardware |
|
|
ds = load_dataset("BramVanroy/CommonCrawl-CreativeCommons", "CC-MAIN-2019-30") |
|
|
|
|
|
# Single language, all dumps -- very large, you will likely need streaming |
|
|
ds = load_dataset("BramVanroy/CommonCrawl-CreativeCommons", "nld", streaming=True) |
|
|
|
|
|
# Single language, single dump |
|
|
ds = load_dataset("BramVanroy/CommonCrawl-CreativeCommons", "CC-MAIN-2019-30-nld") |
|
|
``` |
|
|
|
|
|
## Fields |
|
|
|
|
|
In some cases, multiple licenses are found on a single page. All licenses are collected in `potential_licenses`. From these, the "best guess" is selected |
|
|
based on three criteria: |
|
|
|
|
|
1. location_preference_order: meta_tag, json-ld, link_tag, a_tag |
|
|
2. head_preference_order: True, False |
|
|
3. footer_preference_order: True, False |
|
|
|
|
|
Based on these criteria, the "best guessed" license is picked as the one in the `license_*` columns. Potential disagreement between multiple licenses is given in `license_disagreement`. |
|
|
|
|
|
- text: the extracted text (unmodified) |
|
|
- id: WARC-Record-ID |
|
|
- dump: Common Crawl crawl |
|
|
- url: original url for document |
|
|
- date: crawl date |
|
|
- file_path: file path on the S3 bucket |
|
|
- license_abbr: the license type. Possible values: "cc-unknown" (recommended to filter this one out), "by", "by-sa", "by-nd", "by-nc", "by-nc-sa", "by-nc-nd", "zero", "certification", "mark". If multiple licenses were found (`potential_licenses`) |
|
|
- license_version: the license version, e.g. "4.0" |
|
|
- license_location: the location where the license was found. Possible values: "meta_tag", "json-ld", "link_tag", "a_tag" |
|
|
- license_in_head: whether the license was found inside a `head` HTML element |
|
|
- license_in_footer: whether the license was found inside a `footer` HTML element, or an HTML element that had `footer` in the ID or class name |
|
|
- potential_licenses: |
|
|
- abbr: list of all found license abbreviations |
|
|
- version: list of all found license versions |
|
|
- location: list of all found license locations |
|
|
- in_head: list of whether licenses were found in the head |
|
|
- in_footer: list of whether licenses were found in a footer |
|
|
- license_parse_error: whether there was a problem when trying to extract the license, e.g. an unparseable HTML document |
|
|
- license_disagreement: whether the `potential_licenses["abbr"]` disagree, i.e., different types of licenses were found. License *versions* are not included in the comparison! |
|
|
- language: the language, as detected by glotlid |
|
|
- language_score: the language identification confidence score |
|
|
- found_in_fw: whether this sample was found in FineWeb(-2). For non-English, crawls that are more recent than FW2 (everything after 2024-18) is marked as None. For English, crawls that are more recent than FW v1.3 is marked as None (after 2024-51). |
|
|
|
|
|
|
|
|
## Progress |
|
|
|
|
|
In the `v1` release, the following crawls are included |
|
|
|
|
|
- CC-MAIN-2019-30 |
|
|
- CC-MAIN-2020-05 |
|
|
- CC-MAIN-2023-06 |
|
|
- CC-MAIN-2024-51 |
|
|
- CC-MAIN-2024-46 |
|
|
- CC-MAIN-2025-05 |
|
|
- CC-MAIN-2022-05 |
|
|
|
|
|
Other crawls are continuously being added. |
|
|
|
|
|

|
|
|
|
|
- Afrikaans: afr |
|
|
- German: deu |
|
|
- English: eng |
|
|
- French: fra |

## Quantity |
|
|
|
|
|

|
|
|
|
|
## Recommendations and Caveats |
|
|
|
|
|
- Raw CommonCrawl data is processed in an attempt to extract licensing information. No quality filtering is done!! It is **highly** recommended to filter this data further on quality, fluency, toxicity, etc. |
|
|
- Similarly, the data has **not been deduplicated**. |
|
|
- The licenses include all possible Creative Commons licenses, including non-commercial ones. Take care about what kind of data you wish to use, and filter out non-commercial licenses when needed. |
|
|
- The column `license_disagreement` indicates whether multiple licenses were found that have not the same abbreviation, e.g. `cc-by` and `cc-by-nc`. It is recommended to filter these out. |
|
|
- The column `license_parse_error` indicates whether an error occurred when parsing the license. You probably want to filter out documents where this was the case, though this should be extremely rare. |
|
|
- Unsurpisingly, the data contains a lot of Wikipedia/Wikimedia content. Depending on what you need, you may wish to filter those out. For Wikipedia specifically, you may opt to use the more thoroughly parsed (but potentially more outdated) [wikimedia/wikipedia](https://huggingface.co/datasets/wikimedia/wikipedia) set. |
|
|
- In exceptional cases, a link to creativecommons.org is found but the exact license could not be found. These are under `license_abbr="cc-unknown"` which you may wish to filter out. |
|
|
|
|
|
|
|
|
Recommendation: |
|
|
|
|
|
```python |
|
|
from datasets import load_dataset |
|
|
|
|
|
|
|
|
ds = load_dataset("BramVanroy/CommonCrawl-CreativeCommons", "CC-MAIN-2019-30", split="train") |
|
|
ds = ds.filter( |
|
|
lambda x: ( |
|
|
(not x["license_disagreement"]) and # Only use pages with a consistent license |
|
|
x["found_in_fw"] and # Only use pages that are in FineWeb(-2) |
|
|
"nc" not in x["license_abbr"] and # Exclude non-commercial licenses |
|
|
x["license_abbr"] != "cc-unknown" and # Exclude unknown licenses |
|
|
"wiki" not in x["url"] # Exclude Wiki-like pages (best to get those from a more reliable parser) |
|
|
), |
|
|
num_proc=16 |
|
|
) |
|
|
``` |
|
|
|
|
|
## Personal and Sensitive Information |
|
|
|
|
|
This dataset is a heavily filtered version of the Common Crawl dataset. CommonCrawl respects robots.txt and will not include websites if their robots.txt say so. Even so, if you find that your website was included you can submit a [removal request](https://docs.google.com/forms/d/e/1FAIpQLSddAIuUui5xnAzBqft6MnzPYihr-AaS-Nj8x01Y6AM8NQ0YLQ/viewform?usp=sharing) indicating that you are the owner of the website. |
|
|
|
|
|
Take-down notices on other Common Crawl-based datasets such as FineWeb are considered. Domains specified and verified in those take-down notices are not included in this dataset. |
|
|
|
|
|
In this dataset, measures are taken to anonymise email addresses and public IP addresses following the [FineWeb-2 approach](https://huggingface.co/datasets/HuggingFaceFW/fineweb-2#personal-and-sensitive-information-and-opt-out). Email addresses matching a regular expression are replaced with `firstname.lastname@example.org`. Similarly, IP addresses allocated for [public networks](https://www.iana.org/assignments/iana-ipv4-special-registry/iana-ipv4-special-registry.xhtml) are replaced by unused IP addresses. Despite these best efforts on such large volumes of text, you may still encounter that your personal information is present in the dataset. In that case you can submit a [removal request](https://docs.google.com/forms/d/e/1FAIpQLSddAIuUui5xnAzBqft6MnzPYihr-AaS-Nj8x01Y6AM8NQ0YLQ/viewform?usp=sharing). |
