Summary
Concept mapping — linking an institution’s local codes to standard vocabularies (SNOMED, LOINC, RxNorm…) — is a full step of data preparation. It is a major module of Linkr, with its own documentation section.
A step in preparing data
Preparing a warehouse before analysis means describing its schemas, loading its databases, checking their quality and, often, aligning its vocabulary with standard terminologies. This last step makes data interoperable and comparable across institutions.
Because concept mapping spans several steps on its own (mapping projects, target concepts, editor, AI-assisted suggestions, review, export), it is documented in a dedicated section rather than on a single page.
See the Concept mapping section
The whole module’s documentation lives in the Concept mapping section:
- Overview — what mapping is for and how it is organised.
- Mapping projects — create and organise your projects.
- Target concepts — prepare the destination vocabularies.
- Mapping editor — the main screen.
- Suggestions — AI-assisted pre-mapping.
- Evaluation — review and validation.
- Export — produce a usable file (SSSOM, OMOP, Usagi).
