Figure 3. Ontology VO supports asserted and inferred hierarchies.

Figure 3

(A) Asserted VO hierarchy of 8 bacterial and viral vaccines. Note that the term ‘live attenuated vaccine’ has no asserted child term. (B) Inferred hierarchy after using Fact++ description logic reasoner [70]. The results were extracted from the VO using OntoFox [51] and displayed using the Protégé ontology editor [121]. No specific vaccines were asserted under live attenuated or inactivated vaccines. However, after reasoning, 6 vaccines were inferred to be different types of live attenuated vaccines and 2 other vaccines were inferred as inactivated vaccines. VO: Vaccine Ontology. Data taken from VO.
