 ## NER approach
 For the **NER** model based approach (e.g [StarPII](https://huggingface.co/bigcode/starpii)), please go to the `ner` folder. 
 
-We provide the code used for training a PII NER model to detect : Names, Emails, Keys, Passwords & IP addresses (more details in our paper: [StarCoder: May The Source Be With You](https://drive.google.com/file/d/1cN-b9GnWtHzQRoE7M7gAEyivY0kl4BYs/view)).  You will also find the code (and `slurm` scripts) used for running PII Inference on [StarCoderData](https://huggingface.co/datasets/bigcode/starcoderdata), we were able to detect PII in 800GB of text in 800 GPU-hours on A100 80GB.

To replace secrets we used the following tokens:
 `<NAME>, <EMAIL>, <KEY>, <PASSWORD>`
 To mask IP addresses, we randomly selected an IP address from 5~synthetic, private, non-internet-facing IP addresses of the same type.
 
 ## Regex approach
-Below we explain the regex based approach to dectect Emails, IP addresses adn keys only:
+Below we explain the regex based approach to detect Emails, IP addresses and keys only:
 We use regexes for emails and IP addresses (they are adapted from [BigScience PII pipeline](https://github.com/bigscience-workshop/data-preparation/tree/main/preprocessing/training/02_pii)). And we use [detect-secrets](https://github.com/Yelp/detect-secrets) for finding secrets keys. We additionally implement some filters on top to reduce the number of false positives. There is also some evaluation code to test the pipeline on a PII benchmark we annotated.
 
 ## Usage of the regex approach

 * **fertility**: filter based on the character to token ratio after calling the tokenizer on the code file. Different thresholds for Python (2.5), Java (2.9) and JavaScript (2.6) for data after near-dedup + basic filtering & PII redaction.
