I am building a classifier for short texts in a chat system. My features are words and pairs of words.
Naturally, the sentences contain spelling mistakes. If a particular wrong spelling of a certain word hasn't appeared in the training corpus, the classifier has no chance to identify it.
I consider taking an existing spelling corrector, and integrate it with my current classifier, but I am not sure how to do it.
Do you know of a paper that integrates an automatic spelling correction tool with a short text classifier?
