about
nx_survey_sentiment.nx -- sovereign open-text SENTIMENT for survey free-text answers.
A faithful INTEGER reimplementation of lexicon-based sentiment (VADER-style): a valence lexicon +
negation flip + intensifier boost + the VADER compound normalization compound = S / sqrt(S^2 + alpha).
EVIDENCE (banked 2024-26, knowledge/library/swc_svy_sent.txt): "VADER", "lexicon-based", "polarity",
"Opinion Mining" -- the method is grounded; this adds emotional VALENCE beside the frequency themes so the
admin sees not just WHICH words recur but whether the written feedback is warming or cooling. Admin-only:
like the theme extractor it reads the free text that is WALLED from every public page (never leaks).
All arithmetic is integer fixed-point: valences carry MILLIS (AFINN -4..+4 scale x1000), compound is
PERMILLE (-1000..+1000). Deterministic + KAT-exact (gate nx_survey_sentiment_gate). No float, no LLM.
Imports quality (which brings stats+engine+seg_store) so the serve layer gets the whole survey lib
through one import; st_isqrt (stats) is used for the compound normalization.
