I can’t get over how phenomenal this is. Please put every one of your side project ideas into production!
One small nit from a user experience point of view..: it'd be easier on the eyes if you just truncated those cosine similarity scores (or whatever score you're using) after the, say, 5th digit. Showing the entire float is kinda messy to my eyes.
two spaces after a period
Whether someone uses an em-dash/single hyphen/double hyphens (which may correspond to house style they're used to)
Whether they use semi-colons
(Presumably harder) but consistent substitutions like loose for lose, break for brake, etc.
Use of accents
Fingerprinting certain linguistic traits and mapping that to time-zones as well as confirming there is a partial overlap in posts but never exact worked exceedingly well. Someone can't easily maintain a fluent conversation between themself on two accounts, but they can either get close, either through unnatural delays between sentences or just never interacting with the "other" party at the same time.
