Figure 1.

Example part of an anatomy ontology. The figure shows a small yet comprehensive example anatomy ontology to illustrate regions as well as local (l c(c)) and aggregated (a c(c)) costs (left). For instance, the region ‘lung’ consists of three concepts and has aggregated costs of four. The table on the right shows the corresponding results when applying the region measures (a b s_s i z e, a b s_c o s t s, a v g_c o s t s) in this example.
