Example compilation of the textual descriptors t of vaccine codes X, Y1, Y2, and Y3 into classes in VaccO. Above: VaccO classes are identified in the code descriptors (blue boxes in the source and target code descriptors on the left) and compiled into vaccine classes (V(X), V(Y1), ...). Below: Representation of the vaccine descriptors in the VaccO similarity methods. The classes identified in the descriptor of code X do not overlap with those in the descriptors of codes Y1, Y2, or Y3, and the DL-expressions are not equivalent, resulting in a similarity of 0 for similarity methods Classes and Equivalence and a missing alignment for X. However, property values of code X and the target codes overlap, and X is assigned in Properties to code Y1, which has maximal similarity with X (Y1: 0.5, Y2: 0.3, Y3: 0)
