There was a problem hiding this comment.
Taking a look at some related sample data, it appears that this regex would group a statement such as "I am sooooo happy" with "I am soo happy" (x2 characters), which still doesn't quite reach the intended token of "so".
I'm not certain this works as intended in some of the cases the pull request was expecting. Perhaps there is another approach that might work better? (If not, a project-specific preprocessor is always an alternative option to including one in the main codebase.

Add a preprocessor that reduces runs of three or more repeated letters
down to two (e.g. "sooooo" -> "soo"). Elongated words are common in
conversational input, and normalizing them maps spelling variations to a
consistent form so the chat bot can match input against trained
statements more reliably.
Repeated digits and punctuation are left unchanged, and naturally
occurring double letters (such as the "oo" in "cool") are preserved.
Includes unit tests and documentation for the new preprocessor.
