We explore how virtual examples (artifi- cially created examples) improve perfor- mance of text classification with Support Vector Machines (SVMs). We propose techniques to create virtual examples for text classification based on the assump- tion that the category of a document is un- changed even if a small number of words are added or deleted. We evaluate the pro- posed methods by Reuters-21758 test set collection. Experimental results show vir- tual examples improve the performance of text classification with SVMs, especially for small training sets.
