Computing the shortest paths between two terms. Figure 2 presents the principle for the computing of the shortest paths sp between two MedDRA terms (Abdominal abscess and Pharyngeal abscess) and between the elements of their formal definitions (axis Disorders and Body structure). Blue nodes are inherited from MedDRA, red nodes from SNOMED CT.
