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 logging in with 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.
