We investigate the current extent of term reuse and overlap among biomedical
ontologies. We use the corpus of biomedical ontologies stored in the BioPortal
repository, and analyze three types of reuse constructs: (a) explicit term reuse,
(b) xref reuse, and (c) Concept Unique Identifier (CUI) reuse. While there is a
term label similarity of approximately 14.4% of the total terms, we observed that
most ontologies reuse considerably fewer than 5% of their terms from a concise
set of a few core ontologies. We developed an interactive visualization to
explore reuse dependencies among biomedical ontologies. Moreover, we identified a
set of patterns that indicate ontology developers did intend to reuse terms from
other ontologies, but they were using different and sometimes incorrect
representations. Our results suggest the value of semi-automated tools that
augment term reuse in the ontology engineering process through personalized
recommendations.
