NorMedTerm is a large Norwegian lexical resource of medical entities mapped to semantic categories. The resource contains over 77,000 unique entries and merges terms from several medical databases. Most terms are mapped based on database information, some (ca. 14%) are automatically mapped based on heuristics, of which a smaller amount (ca. 1000 terms) were also manually evaluated and revised.
This work is funded by the Norwegian Research Council, more specifically by the BigMed project.
The resource is distributed as a TAB-separated file, with the following columns:
- term
- semantic category of entity
- source ID (acronym of list / database)
- ICD code (if applicable)
- mapping method ('manual' or 'automatic')
The following 12 semantic categories are included:
| Category | Explanation |
|---|---|
| ABBREV | abbreviations and acronyms |
| ANAT-LOC | anatomical locations |
| CONDITION | diseases, findings, symptoms |
| DISCIPLINE | medical disciplines / areas |
| MICROORGANISM | bacteria, viruses etc. |
| ORGANIZATION | institutions etc. |
| OTHER | category other than the ones specified |
| PERSON | types of practitioner or patient |
| PHYSIOLOGY | physiological functions |
| PROCEDURE | medical procedure and treatment types |
| SUBSTANCE | medicines and other substances |
| TOOL | medical instruments and tools |

| Source ID | Source name |
