We proposed a simple and efficient approach which can incorporate the information of unlabeled news corpus and the information of training data to merge similar features. In our approach, features were divided into two sides according to initial training process, and word2vec tool was utilized to produce auxiliary vectors for each feature. Finally, fast community detection algorithm was applied for clustering similar features. Experimental results show that our approach outperforms raw features and common dimensionality reduction techniques in most cases.1043283 bytesapplication/pdf論文公開時間: 2016/3/8論文使用權限: 同意無償授權立場偵測中文新聞立場偵測特徵合併自然語言處理機器學習stance classificationstance classification on Chinese newspaperfeature clusteringnatural language processingmachine learningthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/275584/1/ntu-105-R02922010-1.pdf
