A novel algorithm of extracting hierarchies with the maximal F-measure for improving multilabel classification performance, the PHOCS, builds Predicted Hierarchy Of Classifiers. Nodes contain classifiers, and each intermediate node corresponds to a set of labels, and a leaf node to a single label. Any classifier in the extracted hierarchy deals with a(More)
The problems of taxonomy evaluation criteria comparison and corresponding benchmark creation are considered. The classes of Primitive Ideal Taxonomies (PITs), their WordNet and disrupted versions are proposed as the sets of benchmark taxonomies for the comparison of taxonomy evaluation methods. For WordNet PITs and their perturbations, the performances of(More)
