On large amount of document category quantity, hierarchical text classification is an effective approach. However, classification methods using the top-down approach suffer from blocking. To address the problem, this paper proposes an improved hierarchical classification method, namely restricted voting method. Our experiments using Rocchio classifiers on the elementary education subjects resource have shown that it can reduce blocking and improve the classification performance.
