Fig. 1From: Automated SNOMED CT concept and attribute relationship detection through a web-based implementation of cTAKESA representation of a unqualified relationship between Non-small cell lung cancer and Recurrent (1) and an attribute relationship of Non-small cell lung cancer with Recurrent as Clinical course (2). The attribute relationship is modelled as a SNOMED CT concept definition diagram of recurrent non-small cell lung cancer (a new post-coordinated expression). Purple blocks represent defined concepts, blue blocks represent primitive SNOMED CT concepts and yellow blocks represent attributes. Attribute groups are represented using a white circle, and conjunctions are represented using a black dotBack to article page
