AI-generated feedback messages shown to young learners solving mathematics exercises in the Levebee educational application, paired with their English translations. The messages are short instructional hints and encouragements ("Choose the picture...", "Try listening to the instruction again.") whose source languages include Czech, Slovak, Polish, German, Hungarian, Romanian, Ukrainian, Russian, Mongolian, and Vietnamese. The corpus is a realistic, quirk-preserving benchmark for the package's embedding, similarity, segmentation, and topic-modeling workflow: translations repeat (templates such as "Try again." recur), some source messages remain in their original language, and a few are identical to their translation.
Format
A data frame with 8,757 rows and 2 character columns:
- feedback
The original feedback message in the source language.
- translation
The English translation of the message.
There are 8,005 distinct translations. Messages are at most 193 characters long.
Source
Anonymized export of the AI mathematics feedback of the Levebee educational application (<https://www.levebee.com/>), December 2025. The messages address learners generically and contain no personal names or identifiers.
