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.

We consider ontology evolution in a system of light-weight Linked Data ontologies, aligned with each other to form a larger ontology system. When one ontology changes, the human editor must keep track of the actual changes and of the modifications needed in the related ontologies in order to keep the system consistent. This paper presents an analysis tool MUTU, by which such changes and their potential effects on other ontologies can be found. Such an analysis is useful for the ontology editors for understanding the differences between ontology versions, and for updating linked ontologies when changes occurred in other components of an ontology system.
