yaaba-instruct

22,164 conversation turns in Mooré and French, the instruction data behind yaaba-4B. Mooré (mos) is spoken by about eight million people, mostly in Burkina Faso.

None of it is machine-translated. Every turn is built from written or transcribed Mooré: press, dictionaries, proverb collections, field interviews, a TV series and Bible text. Where a turn was assembled from a template, its content is still attested.

Fields

• messages: one user turn and one assistant turn, in chat format.
• task: one of the nine tasks above.
• variant: the language of the question then of the answer, when the task has several (mos_mos, fr_mos, mos_fr, fr_fr), or the kind of turn.
• register: lexique, ecrit, entretien, enquete, presse, oral, and a few smaller ones.
• formulation: where the text comes from. attestee means both sides are taken from a document as is; assemblee means an attested template filled with attested content; entree_degradee means the Mooré input carries a real typing error and the answer is the correct text; consigne_degradee means the instruction is typed carelessly (no accents, no quotes); validee_locuteur means signed off by a speaker; decidee marks the model's identity turns, written by the association.
• source: the document or collection the turn comes from.

Splits are drawn by answer, not by turn, so that the same proverb or the same title never appears on both sides.

Known limits

• Eight-digit numbers (Burkina phone numbers) are replaced by XXXXXXXX; one TV scene reads a number out.
• The lexical register dominates (54% of turns), because dictionaries are the largest clean source.
• A large share of the parallel material is religious.
• The division of dialogue into turns was inferred from layout and line order, and no speaker has reviewed that inference.
• Version of 24 September 2026. Compared with the set used to train yaaba-4B, it drops 996 correction turns whose target merely repeated the input, which taught the model to copy Mooré back instead of answering, and one title written twice in a row.
