Flags

Since version 1.8, it is possible to add custom flags that can be attached to mentions, entities and detached mention parts. Flags are stored in the document.

Flag Editor

The flag editor can be opened via the tools menu. The editor shows a table with four columns, each row representing one flag. A flag is defined by four features (shown in the table from left to right):

  1. Icon: Each flag is associated with an icon to help annotators to recognize it. The icon can be selected from the selection shown on this page. It's recommended to search for a useful icon on the page, as it is much easier to compare and see.
  2. Key: The key is used internally to link to the flags. Each annotation that is flagged stores this key. Initially, the key will be universally unique identifier (UUID), and it can remain this way. For merging and comparing, it is recommended to harmonize the keys in different files. If the key is changed, please note that it should still be unique within the document.
  3. Label: The label is displayed in the menus and user interface. This is what the annotators see.
  4. Target class: Flags can be associated with types of annotations. I.e., each flag can only be assigned to annotations of the kind specified here. There is currently no way of having flags applicable on different annotation types, but it is not a problem to have multiple flags with the same label/icon and different target classes.
