This chapter proposes a specification language known as HCL (Hierarchical Classification Language), designed to describe a hierarchical classification method including the definition of a category tree and training of classifiers associated with the categories.

Abstract

Hierarchical text classification refers to assigning text documents to the categories in a given category tree based on their content. With large number of categories organized as a tree, hierarchical text classification helps users to find information more quickly and accurately. Nevertheless, hierarchical text classification methods in the past have often been constructed in a proprietary manner. The construction steps often involve human efforts and are not completely automated. In this chapter, we therefore propose a specification language known as HCL (Hierarchical Classification Language). HCL is designed to describe a hierarchical classification method including the definition of a category tree and training of classifiers associated with the categories. Using HCL, a hierarchical classification method can be materialized easily with the help of a method generator system.

Analysis and empirical evidence suggest that the evaluation results on some versions of Reuters were significantly affected by the inclusion of a large portion of unlabelled documents, mading those results difficult to interpret and leading to considerable confusions in the literature.

Hierarchically Classifying Documents Using Very Few Words

840 Citations1997Daphne Koller, Mehran Sahami

This work proposes an approach that utilizes the hierarchical topic structure to decompose the classification task into a set of simpler problems, one at each node in the classification tree, which can be solved accurately by focusing only on a very small set of features, those relevant to the task at hand.
