While I agree to Pat's comment about the evaluation quality there is
something else that is important with providing "similarity" relations
in a *Harmonisation* scenario. Even though formalism is lacking such
relations could be of great usefulness for ontology authors when looking
for previous work and good ideas. When adding a goal of harmonisation,
i.e reducing unnecessary work, especially for untrained ontology
workers, such comparative functionalities could be of high value.Ex Web
search and wikipedia kind of linking, while lacking formalist they
provide high values to many. (02)
Many unexperienced ontology workers or modelers have little to no
knowledge of the wast amount of work that already has been performed in
various group so what happens? Intellectual work is redone, often with
the effect of *reduced* ontological quality since a new team often dont
have the ability to repeat all deep thoughts performed by ontological
experts with time on their hands. (03)
Preparing and planning for harmonisation is one possibility to use when
trying to circumvent some of the locks (often mental) that
standardisation or the creation of *one*, *single* or *common to all*
ontological elements. (04)
