Thematic theme creation
Thematic creates themes using it's unassisted NLP AI, which is then refined by Thematic data scientists, and the data set stakeholders.
The initial set of themes created by Thematics algorithm are very specific and cover a wide variety of topics. Thematic will merge two themes together which it believes have a similar meaning (eg. "Good experience" and "Great time") and will combine their mapped phrases, which are the terms Themtic uses to tag comments with a theme. Each comment can be tagged by more than one theme, but never the same theme twice.
An example theme with two other similar themes merged into it, and some of the mapped phrases Thematic uses to tag comments
Thematic then tries to group the themes into a 2 level hierarchy of similar topics (eg. Base theme "People", with sub-themes "Friendly", "Grumpy" or "Rude")
Example base theme with it's sub-themes sorted by Thematic
This list of themes is then sense checked by a data scientist at Thematic and then handed to the data set stakeholders, who can make more refinements using the in portal theme editor. The types of refinements typically include
- Removing unhelpful or unactionable themes
- Merging similar themes together
- Creating new themes and moving themes under them
- Adding contextual understanding to the themes (eg. Users rarely say UI, but a UI base theme can be useful for analysis)
- Adding or removing existing mapped phrases to tighten up the accuracy of the themes
Thematic can also run more theme discovery when new data is loaded, or if a specific topic is desired. These new themes with typically be put into a holding theme until a data set stakeholder can double check them, and then move them into the existing hierarchy.
