They generate the pairs from Hindi WordNet, apply parameter-efficient fine-tuning, and test it on a language-learning task.\n\nWhat stands out is the scale of the generated data and the focus on low-resource settings where WordNet already exists. This is a practical demonstration rather than a new algorithm, but it shows one workable route for languages that have structured lexical databases.\n\nThe soft spot is the evaluation. The abstract reports 91.0 pedagogical effectiveness against 79.4-83.6 for general models, yet gives no protocol, no description of the test items, no information on how the baselines were prompted or evaluated, and no statistical details. Without those controls the numeric gap cannot be read as evidence that the structured-data approach is responsible. Semantic performance is called competitive but no numbers appear.\n\nThe paper is aimed at people building task-specific systems for low-resource languages who already have WordNet or similar resources. A reader looking for a worked example of data generation plus efficient fine-tuning will find usable steps.\n\nIt deserves peer review so the authors can supply the missing evaluation details and let referees check whether the comparison holds.
