 # PolyFact
 
-Parallel multilingual factual multiple-choice QA grounded in Wikidata. 100K facts × 12 languages, fully aligned by `fact_id` across all per-language configs.
+Parallel multilingual factual multiple-choice QA grounded in Wikidata. 100K facts x 12 languages, fully aligned by `fact_id` across all per-language configs.
 
 ## Usage
 
 ```python
 from datasets import load_dataset
 
-# One language at a time (SFT / eval)
 ds = load_dataset("jvonrad/PolyFact", "en")
 print(ds["train"][0])
 
-# All languages aligned per fact (cross-lingual training)
 par = load_dataset("jvonrad/PolyFact", "parallel")
 print(par["train"][0]["translations"]["en"])
-Schema
-Per-language configs (ar, bn, de, en, es, fr, id, ja, pt, ru, sw, zh) — flat, one row per (fact, language):
+```
 
-Column	Type	Description
-fact_id	string	Cross-language join key — `<subject_qid>language	string	ISO language code
-subject	string	Subject entity label
-relation	string	Relation name (e.g. educated at)
-object	string	Object entity label (the canonical answer)
-question	string	Natural-language question in language
-option_a..option_d	string	Four multiple-choice options
-answer_text	string	The correct option as text (matches one of option_a..option_d)
-answer_index	int	0-based index of the correct option
-For Wikidata Q-/P-ids (subject_id, property_id, object_id), load the parallel config and join on fact_id.
+## Schema
 
-parallel config — one row per fact:
+**Per-language configs** (`ar`, `bn`, `de`, `en`, `es`, `fr`, `id`, `ja`, `pt`, `ru`, `sw`, `zh`) - flat, one row per (fact, language):
 
-Column	Type	Description
-fact_id, subject, subject_id, relation, property_id, object, object_id	—	Shared across languages; Wikidata grounding lives here
-translations	dict	{lang_code: {question, option_a..d, answer_text, answer_index}}
-Splits are parallel across languages: every fact_id in a split is present in all per-language configs.
