Abstract:

The authors propose C&W-SP model — a text sentiment analysis model based on the representation learning. Firstly, an improved training model based on C&W model is proposed which can integrate emotional information and part of speech information in the training process of word embedding. The evaluation of data sets of NLP&CC’2013 is used to compare experimental results with different models. The experimental results show that the C&W-SP model which combines emotion information and part of speech information has the best performance and confirm the effectiveness of the proposed method.

Key words: sentiment analysis, representation learning, deep learning, word embedding

摘要：

提出一个基于表示学习的文本情感分析模型C&W-SP。首先基于C&W模型的词表示改进训练模型, 实现在词表示训练过程中融入情感信息和词性信息的不同模型设计; 然后利用NLP&CC’2013中的评测数据集, 进行多种模型的实验对比。实验结果表明, 融入情感信息和词性信息的C&W-SP模型性能效果最优, 验证了所提方法的有效性。
