Hierarchical Classification refers to assigning of one or more suitable categories from a hierarchical category space to a document. While previous work in hierarchical classification focused on virtual category trees where documents are assigned only to the leaf categories, we propose a top-down level-based classification method that can classify documents to both leaf and internal categories. As the standard performance measures assume independence between categories, they have not considered the documents incorrectly classified into categories that are similar or not far from the correct ones in the category tree. We therefore propose the Category-Similarity Measures and Distance-Based Measures to consider the degree of misclassification in measuring the classification performance. An experiment has been carried out to measure the performance four proposed hierarchical classification method. The results showed that our method performs well for Reuters text collection when enough training documents are given and the new measures have indeed considered the contributions of misclassified documents.
