Abstract

In order to cope with the problem of data sparsity and curse of dimensionality in text classification, this paper proposed a short text classification framework by taking keyword as features and assigning keyword similarity as feature weight. First, it trained a word2vec model with large corpus data, then got keywords of each category text by textrank. And it selected unique keywords from the keywords collection as features. For each feature, it calculated the similarity of words in the short text by word2vec model, and assigned the maximum similarity as the weight of the feature. Finally, it chose KNN and SVM as classifier. Experiments on dataset of Chinese news headlines demonstrate that the accuracy outperforms other usual methods by 6%.
