Using Multi-Label Classification for Improved Question Answering
Table 3: Different Feature Combinations. (Question Word QW, Number of Token #T, Location Loc, Person Pers, Query Resource Type QRT)
['[BOLD] Feature Combination', '[BOLD] F1-Score']
To probe the influence of the different features on the performance of the metasystem, we trained on all questions and the PSt classifier, using different combinations of features. We avoided using cross-validation due to the small number of potential data points.
