Methods flowchart. This figure illustrates how the methods used in this study are linked to each other. Except for the inputs shown in the figure KSH97-P and SNOMED CT's concepts, relationships and descriptions are used in all methods.
The methods build upon the baseline category mapping that was manually built in the previous study . The initial chapter mapping is manually built in this study and the baseline category mapping is converted to the same SNOMED CT version as the initial chapter mapping. The category mapping and chapter mapping are put together and are manually compared to each other and the mappings are updated. The category mapping is used to create the statistical chapter mapping. The statistical chapter mapping and the manually created chapter mapping are manually compared to each other and the manual chapter mapping is updated. The chapter mapping and category mapping are used for creating the multiple chapter division and the category mapping are used for creating the additional attributes.
