Figure 4. Similarity to target (Thermodynamic_State) vs. similarity to source (Seminar).

Semantic navigation (red trajectory) behaves similarly to shortest path (green trajectory): there are only two degenerated shortest paths and one of them coincides with the semantic path. This example shows that semantic navigation efficiency can be optimal in some cases, because the number of jumps equals to that of shortest path navigation. Conversely, shortest paths sometimes can (accidentally) yield coherent paths in terms of meaning. The remaining similarity pairs with the rest of the network are depicted as a scatter plot.
