Crowd workers rated sentences from four genres (news, blogs, emails and Yahoo Answers) on a scale from -3 (very informal) to +3 (very formal), and the agreement among raters is measured. A ridge regression model is then trained on eleven groups of features: n-grams, word embeddings, POS tags, parse productions, dependency tuples, entity types, casing and punctuation, a frequency-based formality score, readability, language-model perplexity and a lexicon. Cross-validated, the full model beats the strongest n-gram baseline by up to 11 points, and the feature ablation shows that n-grams and embeddings carry most of the signal. As a test of real style rather than topic, a pairwise task asks which of an original sentence and its rewrite is more formal: the model is right 88 percent of the time, while readability alone gets 57 percent. Applied to online debates, formality tracks lower shared context and other pragmatic ratings, as the theories predict. ## Ideas - I1. Build a count-based formality score for each meta token from function-word and POS-tag frequencies, in the spirit of the paper's frequency-based score, and sum it over a frame. Counts are deterministic and easy to audit. - I2. Use the pairwise test as a measure. Given a source sentence and a standard rewrite, check whether the score prefers the author's version. Keep the readability-only baseline as the negative control, since 57 percent is the floor the paper reports. - I3. Train and score per genre, as the paper does, so a register delta is learned per style class (open problem 8). Do not pool genres when the labels differ. - I4. Run a feature-group ablation for the translator's meta-token features (open problem 4): drop one group at a time and report the change on held-out verses. ## For Mova The code is `tools/translate` (`meta.rs` for the meta-token features, `measure.rs` for the pairwise test). The ridge model is not for Mova, but the feature groups and the pairwise check are. They address open problem 4 (function words and boundaries as features) and open problem 8 (style deltas per class).
