One key difficulty with text classification learning algorithms is that they require many hand-labeled examples to learn accurately. This disser-tation demonstrates that supervised learning algorithms that use a small number of labeled examples and many inexpensive unlabeled examples can create high-accuracy text classifiers. By assuming that documents are(More)
