MOBIUSI INCThis dataset provides structured question-answer examples about representative errors made by French learners, addressing why an expression is incorrect, which grammar or usage rule applies, and how to express the intended meaning correctly. Records can include the erroneous expression, learner question, error analysis, corrected expression, applicable rule, and supporting reference details such as title, excerpt, and locator. It is designed for supervised fine-tuning and evaluation of French learning assistants, grammar correction systems, and domain-specific question-answering models.
