Defining a taxonomy for machine learning topic detection


Define the taxonomy that you want to use for topic detection. You can use an existing taxonomy, upload your own taxonomy file, or create a new taxonomy.

If you want to upload your own taxonomy, prepare a .csv, .xls, or .xlsx file that contains the taxonomy. For guidelines on creating a taxonomy, see Requirements and best practices for creating a taxonomy for rule-based classification analysis on Pega Community.
