Bridging Vaccine Ontology and NCIt vaccine domain for cancer vaccine data integration and analysis

Abstract

ABSTRACT The Vaccine Ontology (VO) is a community-based ontology in the domain of vaccines and vaccination. VO is aligned with the Basic Formal Ontology (BFO) and developed by following OBO Foundry principles. National Cancer Institute (NCI) Thesaurus (NCIt) serves as a reference ontology to facilitate interoperability and data sharing for cancer translational and basic research. To facilitate better cancer vaccine research, we compared the VO and NCIt vaccine domain (NCIt-vaccine) and examined the possibility of bridging and integrating these two ontologies. Our results showed that only a small portion of vaccine terms overlap between the two ontologies, and VO and NCIt-vaccine are complementary in different aspects. It is possible to integrate, map, and merge them. This study can be used as a use case for achieving the broader goal of merging and integrating NCIt and OBO library ontologies
