What counts as a duplicate?

Keywords that match after case and spacing are normalized are merged. Hyphen and plural variants, such as "e-mail" and "email", are flagged for you to decide rather than merged.

Does it use stemming?

No. It applies no language-specific stemming, so variants beyond hyphens and plurals stay separate.

What comes after deduplication?

Group the cleaned list into topics with the Keyword Clusterer.
