+- **BIO Tagging**: Model outputs entities in BIO (Beginning-Inside-Outside) format
+- **Multiple Entity Types**: Supports PERSON, ORG, LOC, and MISC entities
+- **Entity-Level Evaluation**: Metrics calculated at entity level rather than token level
+- **Comprehensive Coverage**: Evaluates across different text domains
