public interface SMOntologyPath extends SMOntology
The similarity between query and case based on the shortest path between query and case node in an ontology.

To compute the similarity between two nodes first the common parent of the nodes is searched. Second, the path is traversed up from query to the common parent and traversed down to the case node. Thereby, each step upward is weighted and each step downward is weighted.

sim = weightUp^#stepsUpward * weightDown^#stepsDownward
