TABLE II: Details of three data sets used in this paper.
['Data Set', 'Training', 'Testing', 'Level 1', 'Level 2']
Data set WOS−46985 is the full data set with 46,985 documents, and data sets WOS−11967 and WOS−5736 are subsets of this full data set with the number of training and testing documents shown as well as the number of labels or classes in each of the two levels. For dataset WOS−11967, each of the seven level-1 classes has five sub-classes. For data set WOS−5736, two of the three higher-level classes have four sub-classes and the last high-level class has three sub-classes. We removed all special characters from all three data sets before training and testing.
