微博情感倾向性分析通常指对中文微博中每个句子褒义、贬义或者中性的情感进行自动分类。针对微博碎片化和情感类别失衡的特点，在半监督学习reserved self-training方法的框架基础上提取了适用于微博情感分类的文本特征，并提出了针对情感倾向性分析通过训练度阈值设定的方法来优化reserved self-training迭代终止的条件，在保留reserved self-training能有效处理微博语料中语料情感不平衡问题的优点基础上，防止了训练过度情况的发生。COAE 2014微博情感倾向性评测结果证明了该方法的有效性。
微博情感傾嚮性分析通常指對中文微博中每箇句子褒義、貶義或者中性的情感進行自動分類。針對微博碎片化和情感類彆失衡的特點，在半鑑督學習reserved self-training方法的框架基礎上提取瞭適用于微博情感分類的文本特徵，併提齣瞭針對情感傾嚮性分析通過訓練度閾值設定的方法來優化reserved self-training迭代終止的條件，在保留reserved self-training能有效處理微博語料中語料情感不平衡問題的優點基礎上，防止瞭訓練過度情況的髮生。COAE 2014微博情感傾嚮性評測結果證明瞭該方法的有效性。

Sentiment analysis of Chinese Micro-blog usually refers to classification of Micro-blogs into positive,nega-tive and neutral polarity.According to the characteristics of Micro-blogs,such as fragmentation and imbalanced of sen-timent class,on the basis of reserved self-training method we presented before,text features were extracted that are appropriate for the sentiment analysis of Micro-blog,and then a training degree threshold setup method was proposed to optimize the iteration termination condition of reserved self-training method.These methods not only take advantage of the effective treatment on imbalanced distribution problem but also prevent the overtraining problem in training process. The evaluation result in COAE2014 showed the effectiveness of these methods.
