Table 8 Precision and recall rates from the machine learning approach and CRIS’ pattern matching approach
Types of PI | MIST performance | CRIS performance |
|---|---|---|
Total Number of Notes scanned | 20 | 20 |
Total number of PI instances | 191 | 191 |
Number of PIs correctly identified and masked (True Positives) | 154 | 169 |
Number of PIs that should have been masked (False Negatives) | 43 | 22 |
Number of instances masked that should not have been masked (False Positives) | 8 | 0 |
Precision | 95.1% | 100% |
Recall | 78.1% | 88.5% |
