Hierarchical multilabel classification is a classification problem where an example can belong to more than one class simultaneously and these classes are structured as a hierarchy. This paper describes and evaluates two methods of hierarchical multilabel classification based on decision trees, following the standard local and global approaches, and a new variation method of the local approach, named HMCLabelPowerset. Ten biological datasets with gene functions of the Yeast organism, organized as a tree structure, were used in the experiments. The results show that the local approach can lead to better results, although a more complex set of rules is produced, reducing the interpretability of the induced model.
