This is a review article
This is a clear, precise and well-written article describing the topic. It covers the motivation, process and technology of this approach for the development of a polyhierarchy while being clear that the axiomatisation necessary can have upfront costs. The article also makes clear use of figures demonstrating the use, as well as examples clarifying the more technical statements.
The latter half of the article addresses the issue of normalisation which is a development methodology that enables automatic maintenance of multiple inheritance ontologies. Well this is appropriate material for the article, it is not strictly necessary to completely normalize an ontology to use reasoning. The conclusions, in particular, could be improved in structure by saying that automatic maintaince can be supported by reasoning, and that normalisation exploits this fully.
Otherwise, an excellent article.
The section titles should use HTML headers, rather than the typographic markup used. Authors email should be hyperlinked.
The effort is considerable, but worthy, as the automated reasoner is able to maintain the whole structure, avoiding human errors. Also, using such expressive axiomisation enables richer queries and other advantages.
