Task: Question Answering
Input (English): Yet, it is possible that the precise interpretability scores that are measured here are biased by the dataset used. However, it should be noted that the change in the interpretability scores for different word coverages might be effected by non-ideal subsampling of category words. Although our word sampling method, based on words' distances to category centers, is expected to generate categories that are represented better compared to random sampling of category words, category representations might be suboptimal compared to human designed categories. 
 Question: What are the weaknesses of their proposed interpretability quantification method?
Output (English): can be biased by dataset used and may generate categories which are suboptimal compared to human designed categories
