Rada R, Mili H, Bicknell E, Blettner M: Development and application of a metric on semantic nets. Ieee Transactions On Systems Man And Cybernetics 1989, 19:17-30. In this implementation no restriction is made on the shortest path, i.e. if the underlying data structure is a DAG the shortest path can in some case not contain a common ancestor of the compared concepts.
