QuestA joined with OpenR1-Math-220k
This dataset joins foreverlasting1202/QuestA back to the corresponding rows in
open-r1/OpenR1-Math-220k.
Contents
Each row contains the complete OpenR1 fields, including:
solutionproblem_type,question_type, andsourceuuid- all original
generations correctness_math_verifyandcorrectness_llamafinish_reasonsandcorrectness_countmessages
The original QuestA values are retained explicitly as:
questa_indexquesta_problemquesta_answerquesta_generation
The provenance of the selected OpenR1 row is recorded in openr1_config and
openr1_source_index.
Join procedure
Rows were matched by exact problem text and answer, with Unicode/whitespace normalization needed for only seven candidate matches. When the same UUID appeared in both OpenR1 configs, the config containing the exact QuestA generation was selected. Seven QuestA rows had the same problem and answer but multiple distinct OpenR1 UUIDs; these ambiguous rows were dropped.
- QuestA source rows: 12,506
- Joined rows: 12,499
- Dropped ambiguous rows: 7
- Exact retained-generation matches: 12,499
The dropped QuestA indices are recorded in manifest.json.
