From: Unintended consequences of existential quantifications in biomedical ontologies
Occurrence of existential restrictions in DL axioms. Occurrence of existential restrictions in DL axioms in OBO Foundry ontologies and close candidates (left), cross products (right). Rating results as heat map: green - no erroneous restrictions to deep red - only erroneous restrictions. Sample size is encoded as normal font: less than 20 axioms, boldface: 20-39 axioms and italic boldface: 40 and more axioms.
