ROC curves to evaluate different heuristics for ranking of b-terms on the migraine-magnesium training dataset. A curve is constructed by drawing a vertical line when a term is indeed a b-term, and a horizontal line when a term is not a b-term. Therefore, the y-axis shows the number of b-terms and the x-axis shows the number of non-b-terms. The figure presents a selection of the best heuristics, where a comparison of the best, b-potential (leftmost solid line) with the random heuristics (rightmost dashed line) is indicative.
