The coverage assessment for BioThesaurus using the test set of the BioCreAtive workshop. The percentage in the first column shows the percentage of terms in BioCreAtive text present in BioThesaurus. The percentages in the second, third, and last columns were acquired by inversing the ambiguity which refer to the precisions of a base system that randomly picks an associated entity for those ambiguous terms.
