Recently, network services have been increasing and we think it is very important to develop many OSSs (Operation Support Systems) to support these services. We think it will be possible to develop OSS efficiently by the reuse of the deliverables in the past developments. Using ontologies in the new OSS development, we could find models similar to new ones from the deliverables in the past developments. We propose how to calculate the similarity between ontologies.
