Applying labels

User permissions required: ‘View Sources’ AND ‘Review and label’


Apply a single label


  • Navigate to Discover or Explore
  • Click 'Add label +' or just '+' (for verbatims that have predictions) underneath the verbatim to either select labels previously created within this taxonomy or use the text box to create new labels
  • Click enter or the tick icon to apply the label, or if sentiment analysis is enabled click either of the A close up of a logo

Description automatically generated icons to apply the label with positive or negative sentiment


Please Note: The format for label structure should be one of the following:


  1. [Standalone Parent / Root Label]
  2. [Parent / Root Label] > [Leaf Label]
  3. [Parent / Root Label] > [Branch Label] > [Leaf Label]


We do not recommend having more than three levels in a label hierarchy, as it becomes increasingly complex for users to train. In certain cases, this might be required, but it should not be considered best practice.


Apply labels in bulk


Applying labels to groups of verbatims can massively speed up the labelling process:


  • Navigate to Discover – you can use either the cluster functionality or search
  • Use thebutton to either select previously created labels or use the text box to create new labels
  • Add as many labels as necessary to fully annotate the verbatims
  • When you have fully labelled the verbatims double clickto apply these labels to the verbatims you have selected
  • Please Note: all verbatims will automatically be selected, clicking the toggle button on the bottom right-hand corner of a verbatim will de-select it


Next to thebutton are three other buttons:

-  Hide the labels currently applied to the verbatims shown

- Invert your selection so selected verbatims become de-selected and vice versa

- De-select or select all verbatims

Next: Reviewing verbatims
