Do SNOMED CT relationships qualify?
An important feature of SNOMED CT is post-coordination, which is enabled as SNOMED CT specifies refinability of target concepts of relationships. In this paper the use of refinable relationships in SNOMED CT is analysed, and the interplay between refinable and defining relationships. Refinability is used in 10 out of 61 relationships, and the interplay between refinable and defining relationships is low. The results indicate that the usage of refinable relationships can be further enhanced in SNOMED CT.
