Source description
Purpose: This adapter is a style evaluator / judge, not a fiction writer.
It classifies and scores English prose against a 14-metric Leech & Short–derived rubric and emits structured JSON style_profiles (plus short natural-language judgments). Those judgments power a bake-off and later used to train / score a stylish fiction writer and assemble long-form novels that stay on voice, style, and tone.

Training mix (Phase 3 instruction pairs from classified prose):
Approx. 430k train / 48k validation pairs under train/style_training/.
Styled fiction chunks labeled with metadata.style_profile, then converted to instruction pairs. Corpora include (HF sources):
Labels were produced by the Phase 2 pipeline (tools/style_classification/run_pipeline.py): computable metrics (spaCy / textstat) plus LLM semantic metrics grounded in a Style-in-Fiction rubric and RAG knowledge base (source/style_rubric.json, source/extracted/style_knowledge.jsonl).
Derived from Leech & Short, Style in Fiction (2nd ed.), operationalized in source/style_rubric.json (stats.dimensions = 14).
| # | Metric ID | Category | How generated | Values / type |
|---|---|---|---|---|
| 1 | lexical_complexity | Lexical | LLM (Pass 1) | simple_colloquial / neutral / complex_literary |
| 2 | lexical_density | Lexical | Computable | continuous 0–1 (content-word ratio) |
| 3 | register | Lexical | LLM (Pass 1) | formal_literary, formal_technical, neutral_narrative, colloquial, dialect, archaic |
| 4 | sentence_complexity | Grammatical | LLM (Pass 1) |
How those labels were generated:
style_knowledge.jsonl; distill checklist + 14 operational dimensions into style_rubric.json.--pass both: Pass 1 lexical/syntax/discourse + POV; Pass 2 tone / mind style / narrative distance / FID).Additional textual principles in the rubric (end_focus, segmentation, prose_rhythm, climax, ...) may appear in full profiles from the classifier pipeline; the 14 rows above are the core training/eval dimensions for this adapter.
