| Threshhold Heymann alg. | Precision AB | Recall AB | F-measure AB | Precision AB|A..B|BA | Recall AB|A..B|BA | F-measure AB|A..B|BA | |
|---|---|---|---|---|---|---|---|
| MeSH | 0.5 | 0.28 | 0.02 | 0.04 | 0.34 | 0.02 | 0.04 |
| MeSH | 0.1 | 0.15 | 0.11 | 0.13 | 0.21 | 0.17 | 0.19 |
| MeSH | 0.01 | 0.12 | 0.13 | 0.13 | 0.19 | 0.20 | 0.19 |
Results AB only regard relations as correct which exist in MeSH, while AB|A..B|BA also regards prediction of ancestors or the inverse direct relations as correct.
