KOAN
KOAN is a simple tool for finding duplicate concepts in groups of ontologies. It takes a number of ontologis in SKOS format as an input and produces a the number of duplicates between each ontology pair. It can also be used to provide a list of duplicate concepts.
The main intended use for KOAN is in cleaning up the Finnish Collaborative Holistic Ontology KOKO in order to make sure that the different domain ontologies comprising it are in alignment. Below is a table showing the duplicate concepts within a number of different domain ontologies in KOKO.
