This paper introduces a method of short text classification based on semi-supervised learning and builds a semi-supervised classification model. It is feasible to accomplish the self-training of the training samples and takes full advantages of the unlabeled parts of training texts by using the initial classifier. The bottleneck problem of annotation is solved and the good performance of classifier is shown. The contrast experiment shows that the algorithm of short text classification based on semi-supervised learning can get better classified effect.
