Ranganath, Jurafsky & McFarland · EMNLP, 2009 ↗What this tells us
946 complete four-minute dates. On the top and bottom 10% of self-reported ratings, combined prosodic, dialogue and lexical features classified women’s intent at 71.5% accuracy and men’s at 69%. The model outperformed partners on this task. Both genders showed misperception; this is not a universal attraction detector or a Charlotte result.
