What are base and sub-themes?

Thematic works by organically finding themes in your data. Each theme contains mapped phrases that are used to tag responses. A single comment can be tagged with multiple themes.

Example mapped phrases for "Good seats"

  • "amazing seating"
  • "fantastic seats"
  • "seats are great"
  • "seats which was awesome"

Base theme and sub-theme hierarchy

Thematic groups these themes into a two-level hierarchy of base and sub-themes, that can be edited.

  • Base themes are general concepts or topics, while sub-themes are more specific. 
  • Sub-themes are grouped under the most relevant Base theme. 
  • Base theme volume is equal to the number of responses tagged by at least the base theme, and/or one or more of the sub-themes.

An example of a base theme and its sub-themes is "airplane seats" from our airline's demo.

airplane seats (Base theme)

  • seats comfort (Sub-theme)
  • seat space (Sub-theme)
  • airplane seats (other) (Sub-theme)
  • good seats (Sub-theme)
  • seat assignments (Sub-theme)
  • seats in front (Sub-theme)
  • no assigned seating (Sub-theme)
  • middle seat (Sub-theme)
  • seats purchased (Sub-theme)
  • choose a seat (Sub-theme)

What is an (other) sub-theme? 

The (other) sub-theme is used to identify comments that fall under the base themes but not any of its specific sub-themes. This is best for responses that might mention a specific topic without going into more detail. eg. "rude staff, also airplane seats"

Does all the sub-themes volume add up to the base themes volume?

Not necessarily because comments can be tagged with multiple themes, but will only count towards the base theme once.

Editing themes and mapped phrases

Thematic themes and mapped phrases can be edited for any of your data sets. If you have admin rights you can edit themselves in your themes editor, and if you don't you can contact an admin at your organization to help coordinate changes.
