Entity type | Description | Example |
---|---|---|
Condition | Symptom, diagnosis, complication, conditions, problems, functions and processes, injury | In example 1, there are two melanoma entities of type condition: one in the right groin, and one in the right second toe. The melanoma in the right groin has two mentions: "melanoma" and "it". |
Intervention | Action performed by doctor or other clinician targeted at a patient, Locus, or Condition with the objective of changing (the properties) of, or treating, a Condition. | In example 1, there is one intervention entity, the dissection. In example 2, the radiotherapy is an intervention. |
Investigation | Interaction between doctor and patient or Locus aimed at measuring or studying, but not changing, some aspect of a Condition. Investigations have findings or interpretations, whereas Interventions usually do not. | In example 1, there are three investigation entities: a biopsy, a PET scan and a CT scan. |
Result | The numeric or qualitative finding of an Investigation, excluding Condition | In example 1, the PET scan has a result of "normal". Other examples include the numeric values of tests, such as "80mg". |
Drug or device | Usually a drug. Occasionaly, medical devices such as suture material and drains will also be mentioned in texts. These will also be annotated along with drugs. | Example 3 contains a single drug entity, co-codamol. |
Locus | Anatomical structure or location, body substance, or physiologic function, typically the locus of a Condition. | There are five loci entities in example 1: lymph node, the right groin, second toe, the groin that needs a dissection, and pelvic side wall. It is debatable as to whether the two groins are the same entity, although you could perhaps infer that the dissection would be on the groin that contains the melanoma. |
