Table 6 Average speed in CUI concept pairs per second (pairs/s) for the evaluation of random CUI pairs with three representative ontology-based similarity measures based on the SNOMED-CT US 2019AB ontology (357,406 nodes) implemented by the three UMLS-based semantic measures libraries reported in the literature
