On large amount conditions of text quantity, hierarchical text categorization was an effective approach. 摘要在文本分類的類別數量龐大的情況下，層次分類是一種有效的分類途徑。
Finally, experiment results show that the new approach, proposed in this paper, outperforms plain or generic hierarchical methods with improved accuracy. 實驗表明，該方法相對於平面分類和一般的層次分類方法，有較高的準確率。
There is now a hierarchical object store. 現在有一個分層的對象存儲。
That identifies the hierarchical path relative to the current node. 標識相對當前節點的分層路徑。
