MUTU: An Analysis Tool for Maintaining a System of Hierarchically Linked Ontologie
We consider ontology evolution in a system of light weight Linked Data ontologies, aligned with each other to form a large global ontology. When changes occurs in one ontology, it is difficult for the human editor to keep track of what actually has been changed and what modifications in related ontologies may be needed, in order to keep the system consistent. Using MUTU, such changes and their potential effects to other ontologies can be found. Such an analysis in useful for the ontology editors to understand the differences between ontology versions, and for updating related ontologies when changes in other components of the ontology system occur.
