 ## Model Description
 
-This is an Arabic Named Entity Recognition (NER) model fine-tuned on BERT architecture specifically for Arabic text processing. The model is based on `MutazYoune/ARAB_BERT` and has been trained to identify and classify named entities in Arabic text.
+This is an Arabic Named Entity Recognition (NER) model fine-tuned on BERT architecture specifically for Arabic text processing and PII detection. The model is based on `MutazYoune/ARAB_BERT` and trained to identify and mask Personally Identifiable Information (PII) in Arabic sentences.
+
+PII categories covered include:
+
+- Personal names (first, middle, family)
+- Phone numbers
+- Email addresses
+- Physical addresses
+- National ID numbers
+- Bank account information
+- Dates of birth
+
+The model was developed and submitted as part of the **Arabic PII Redaction Challenge** hosted on Hugging Face.
