Recently, hierarchical text classification has become an active research topic. The essential idea is that the descendant classes can share the information of the ancestor classes in a predefined taxonomy. In this paper, we claim that each class has several latent concepts and its subclasses share information with these d- ifferent concepts respectively. Then, we pro- pose a variant Passive-Aggressive (PA) algo- rithm for hierarchical text classification with latent concepts. Experimental results show that the performance of our algorithm is com- petitive with the recently proposed hierarchi- cal classification algorithms.
