In this paper, a new co-training style semi-supervised algorithm is proposed, which employs Bagging based multimodal perturbation to label the unlabeled data. In detail, through perturbing the training data, input attributes and learning parameters together, the algorithm generates accurate but diversity k-nearest neighbor classifiers. These classifiers are refined using unlabeled examples which are...
In this paper, a new method for question classification is proposed, which employs ensemble learning algorithms to train multiple question classifiers. These component learners are combined to produce the final hypothesis. In detail, the feature spaces are obtained through extracting high-frequency keywords from questions corpus and the method of word semantic similarity is performed to adjust the...
