What is the text classification's high limit of classes number? #130

We can use CNN to classify more than 10 thousands of images of the ImageNet. I find that CNN could only classify 10-20 text classes as this paper write. So what is the high limit of short text classification's classes' number?

1) That paper only used 5-10 categories, but that was not due to limitations of the CNN; it was a choice made by the researchers reflecting the nature of the data that they used. 2) That paper has been superceded by https://arxiv.org/abs/1509.01626 3) I do not know of any high limit. The approach is constrained by available data and the computational power requited.
