Abstract: The previous authors’ research showed that it is not only possible, but also profitable to estimate a potential growth of a level of knowledge that appears during an integration of ontologies. Such estimation can be done before the eventual integration procedure (or at least during such) which makes it even more valuable, because it allows to decide if a particular integration should be performed in the first place. Until now, authors prepared a formal framework that can be used to estimate the knowledge increase on the level of concepts, instances and relations between concepts. This paper is devoted to the level of relations between instances.
Keywords: ontology; knowledge increase; instances’ relation; ontology integration
