Abstract

Reification of parthood relations according to the SEP-triplet encoding pattern has been employed in the clinical terminology SNOMED CT to simulate transitivity of the part-Ofrelation via transitivity of the is-arelation and to inherit properties along part-Oflinks. In this paper we argue that using a more expressive representation language, which allows for a direct representation of the relevant properties of the part-Ofrelation, makes modelling less error prone while having no adverse effect on the efficiency of reasoning.
