Objective
A continual problem confronting the implementation of standardized vocabularies such as SNOMED CT is that their expressive flexibility and power provide more than one way to represent a given concept. The goal of this study was to investigate how the CliniClue™ Expression Transformer tool could be used to help in discerning similarities and differences among three separate sets of clinical research concepts coded in SNOMED CT by three different paid expert coding companies.
Methods
Initial editing of the companies’ coded datasets was required to enable accurate input into CliniClue Version: 2006.2.0030 Expression Transformer tool. The normal forms of the …
