Medical text analysis

Annotation manual

The goal is to mark the occurrence of known medical entities or other important information in the text of health records.

You will familiarize yourself with the BRAT annotation tool. After (quite nonintuitive) logging in with the credentials assigned to you, you will be able to highlight the entities to be annotated, after which a pop-up will appear, letting you choose the category of the entity you highlighted.

Within the pop-up, you will choose the category of the annotation and in the Notes field you will be able to enter or correct additional content relevant to the annotation (in the case of Abbreviations, you may correct the meaning of it).

You do not have to specify confidence but if you are unsure if your annotation is correct, you can select the option "Confidence: Low".
