Abstract

Methods and systems for text classification include identifying a text sample, classified according to a first class in a set of hierarchical graphs of classes, that is more similar to a second class in the set of hierarchical graphs of classes than to the first class according to a similarity metric. A word is deleted from the identified text sample that is associated with the second class. A word is added to the identified text sample that is associated with the first class. A text classification model is trained using the text sample as training data. Text classification is performed on an input text using the trained text classification model implemented on a processor device.
