Synonyms Are SubClasses And Higher Taxa Are Just Tags
I have been wrestling for some time with how to handle taxonomic hierarchies when combining multiple classifications. This is partly motivated by a pressure to produce consensus hierarchies for navigation (a task that I think is probably not worth doing but which is beyond the scope of this post) and partly from a need to carry out inference over multiple classifications using OWL (something that I think is an important research topic if we are to overcome the ‘taxonomic impediment’).
Take the simplest scenario where we have classification C1 that contains family Z with two genera X and Y that contain a total of three species Xa, Xb and Yc. Now let there be another classification C2 that is identical but for the species Xb being moved to the genus Y as Yb. Read more…
