## 4 Evaluation Metrics and Experimental Results
### Experimental Results and Analysis
#### 4.3.2 Analysis of Experimental Results  
Table 3 reveals that on the PFR dataset, our proposed CHTopoNER model performs the best across all three evaluation metrics: Precision (P), Recall (R), and F1 score (F1). Compared to the baseline model BiLSTM-CRF, the CHTopoNER model exhibits improvements of 8.5% in P, 17.9% in R, and 12.4% in F1 values. Compared to the state-of-the-art BERT-BiLSTM-CRF model, the CHTopoNER model achieves improvements of 0.1% in P, 6.2% in R, and 2.1% in F1 values. Similarly, from Table 4, on the MSRA dataset, our proposed CHTopoNER model demonstrates superior performance in all the three evaluation \begin{table}
