 # Model Description
 
-* A RoBERTa [Liu et al., 2019](https://arxiv.org/pdf/1907.11692.pdf) model fine-tuned for de-identification of medical notes.
+* A RoBERTa [[Liu et al., 2019]](https://arxiv.org/pdf/1907.11692.pdf) model fine-tuned for de-identification of medical notes.
 * Sequence Labeling (token classification): The model was trained to predict protected health information (PHI/PII) entities (spans). A list of protected health information categories is given by [HIPAA](https://www.hhs.gov/hipaa/for-professionals/privacy/laws-regulations/index.html).
-* A token can either be classified as non-PHI or as one of the 11 PHI types. Token predictions can be aggregated to span (e.g., making use of BILOU tagging).

 * The PHI labels that were used for training and other details can be found here: [Annotation Guidelines](https://github.com/obi-ml-public/ehr_deidentification/blob/master/AnnotationGuidelines.md)
 * More details on how to use this model, the format of data and other useful information is present in the GitHub repo: [Robust DeID](https://github.com/obi-ml-public/ehr_deidentification).
