%0 Journal Article %T Probabilistic Cascading for Large Scale Hierarchical Classification %A Aris Kosmopoulos %A Georgios Paliouras %A Ion Androutsopoulos %J Computer Science %D 2015 %I arXiv %X Hierarchies are frequently used for the organization of objects. Given a hierarchy of classes, two main approaches are used, to automatically classify new instances: flat classification and cascade classification. Flat classification ignores the hierarchy, while cascade classification greedily traverses the hierarchy from the root to the predicted leaf. In this paper we propose a new approach, which extends cascade classification to predict the right leaf by estimating the probability of each root-to-leaf path. We provide experimental results which indicate that, using the same classification algorithm, one can achieve better results with our approach, compared to the traditional flat and cascade classifications. %U http://arxiv.org/abs/1505.02251v1
