Summary
This paper presents a new semi-supervised learning algorithm.
It decomposes multi-class classification problem into n binary ones using ECOC and Co-training is used for learning each individual binary classifier.
Hoovers dataset that contains over 108,000 web pages of different companies. Since there are no natural feature split, the author randomly split the vocabulary into two halves and treat them as two separate feature sets. Another dataset used for experiments is Jobs dataset. Job titles and job description are used separate feature sets for Co-training.
