- Performance measure: F = 2 * Precision * Recall / (Recall + Precision)
- Precision: percentage of named entities found by the algorithm that are correct
- Recall: percentage of named entities defined in the corpus that were found by the program
- Exact calculation of precision and recall is explained in the MUC scoring software
- Training data: Training section of MUC-7 dataset
- Testing data: Formal section of MUC-7 dataset
