OT:
What do the cognoscenti recommend for doing automatic text classification/categorization? I have been looking at Spam filters, and they're mostly boolean type predicates that return Spam/NotSpam results along with a confidence number. I want to be able to do that same for a large number of categories.
- thomaspaine 17y agoFor simple classification tasks, naive bayes performs surprisingly well, is very easy to setup and run, and is relatively computationally inexpensive. It's excellent for getting a good baseline performance approximation because it's just so easy to use. If you have a lot of training data and computational power, an SVM will almost always outperform naive bayes, but they take longer to train and tune. Try naive bayes first.
