 ## Model Behavior & Limitations
 
 - **Evaluation Focus:**  
-  The metrics shown above reflect performance on the test split of the [open-pii-masking-500k-ai4privacy](https://huggingface.co/datasets/ai4privacy/open-pii-masking-500k-ai4privacy) dataset. This model not only redacts PII but also classifies it into specific categories (e.g., SURNAME, EMAIL, etc.). Real-world performance may vary depending on the text domain and language, so additional validation is recommended. For support, contact **[email protected]**.
+  The metrics above reflect performance on the test split of the [open-pii-masking-500k-ai4privacy](https://huggingface.co/datasets/ai4privacy/open-pii-masking-500k-ai4privacy) dataset. This model both redacts and classifies PII into specific categories (e.g., GIVENNAME, EMAIL). Real-world performance may vary depending on text domain and language, so additional validation is recommended. For support, contact **[email protected]**.
 
 - **Strengths:**  
-  - High recall (98.49%) ensures most PII is detected.  
-  - Perfect performance (100% F1) on labels like TIME, DATE, and EMAIL.  
+  - High recall (95.76%) ensures most PII is detected.  
+  - Exceptional performance on labels like "EMAIL" (100% F1), "DATE" (99.91% F1), and "TIME" (99.88% F1).  
 
 - **Limitations:**  
-  - Lower precision for certain labels (e.g., PASSPORTNUM at 56.91%) indicates a higher rate of false positives.  
-  - The "O" (Non-PII) label has no true positives, so precision and recall are not applicable (n/a).  
+  - Lower precision for labels such as "PASSPORTNUM" (62.84%) and "DRIVERLICENSENUM" (67.43%), indicating a higher rate of false positives.  
+  - The "O" (Non-PII) label has no true positives, making precision, recall, and F1 score not applicable (n/a).
