“…In Ráez et al (2004), the issue of class-label imbalance is identified with respect to large text categorisation problems tackled with BR, caused by the inevitable label sparsity, which yields a relatively small number of positive examples in the transformed problems. This work addresses this issue by overweighting positive examples in each of the BR models.…”

“…The columns Inst, Attr and Lbl are respectively the number of instances, attributes and labels. Label sets (lSets) is the amount of distinct label combination, proportion of unique label sets (PUL) indicates the proportion of label sets related to a single instance, label cardinality (lCard) measures the average number of labels per instance, label density (lDen) describes the average frequency of labels, dependency (Dep) shows the average unconditional labels' dependency (Luaces et al 2012), inner imbalance degree (IID) measures the average label imbalance in the binary data sets (Raez et al 2004) and, finally, correlation (Corr) indicates the average correlation between the predictive attributes and the labels.…”
