The target entities are: Names, Usernames, Emails, IP addresses, Keys, Passwords, and IDs. The annotation process involved 1,399 crowd-workers from 35 countries with [Toloka](https://toloka.ai/). It consists of **12,099** samples of ~50 lines of code in 31 programming languages. You can also find a PII detection model that we trained on this dataset at [bigcode-pii-model](https://huggingface.co/loubnabnl/bigcode-pii-model). ## Dataset Structure You can load the dataset with: ```python from datasets import load_dataset ds = load_dataset("bigcode/bigcode-pii-dataset", use_auth_token=True) ds ``` ```` DatasetDict({ test: Dataset({ features: ['text', 'type', 'language', 'fragments', 'id'], num_rows: 12099 }) }) ```` It has the following data fields: - text: the code snippet - type: indicated if the data was pre-filtered with regexes (before annotation we selected 7100 files that were pre-filtered as positive for PII with regexes, and selected 5199 randomly) - language: programming language - fragments: detected secrets and their positions and categories - category: PII category - position: start and end - value: PII value ## Statistics Figure below shows the distribution of programming languages in the dataset: The following table shows the distribution of PII in all classes, as well as annotation quality after manual inspection of 300 diverse files from the dataset: | Entity | Count | Precision | Recall | | ---------------- | ----- | --------- | ------ | | IP\_ADDRESS | 2526 | 85% | 97% | | KEY | 308 | 91% | 78% | | PASSWORD | 598 | 91% | 86% | | ID | 1702 | 53% | 51% | | EMAIL | 5470 | 99% | 97% | | EMAIL\_EXAMPLE | 1407 | | | | EMAIL\_LICENSE | 3141 | | | | NAME | 2477 | 89% | 94% | | NAME\_EXAMPLE | 318 | | | | NAME\_LICENSE | 3105 | | | | USERNAME | 780 | 74% | 86% | | USERNAME\_EXAMPLE| 328 | | | | USERNAME\_LICENSE| 503 | | | | AMBIGUOUS | 287 | | | `AMBIGUOUS` and `ID` were not used in our [NER model](https://huggingface.co/loubnabnl/bigcode-pii-model) training for PII detection. # Dataset Creation We selected the annotation samples from [The Stack](https://huggingface.co/datasets/bigcode/the-stack) dataset after deduplication, a collection of code from open permissively licensed repositories on GitHub. To increase the representation of rare PII types, such as keys and IP addresses, we pre-filtered 7100 files from a larger sample. This pre-filtering was carried out using the [detect-secrets](https://github.com/Yelp/detect-secrets) tool with all default plugins activated, in addition to the regular expressions to detect emails, IPv4 and IPv6 addresses. To avoid introducing bias, the remaining 5100 files were randomly sampled from the dataset without pre-filtering. We then annotated the dataset through [Toloka Platform](https://toloka.ai/) with 1,399 crowd-workers from 35 countries. To ensure that crowd-workers received fair compensation, we established an hourly pay rate of \$7.30, taking into consideration different minimum wage rates across countries and their corresponding purchasing power. We limited annotation eligibility to countries where the hourly pay rate of \$7.30 was equivalent to the highest minimum wage in the US (\$16.50) in terms of purchasing power parity. # Considerations for Using the Data When using this dataset, please be mindful of the data governance risks that come with handling personally identifiable information (PII). Despite sourcing the data from open, permissive GitHub repositories and having it annotated by fairly paid crowd-workers, it does contain sensitive details such as names, usernames, keys, emails, passwords, and IP addresses. To ensure responsible use for research within the open-source community, access to the dataset will be provided through a gated mechanism. We expect researchers and developers working with the dataset to adhere to the highest ethical standards and employ robust data protection measures. To assist users in effectively detecting and masking PII, we've also released a PII model trained on this dataset. Our goal in providing access to both the dataset and the PII model is to foster the development of privacy-preserving AI technologies while minimizing potential risks related to handling PII.
