微博用户情感分析main是什么

微博言论往往带有强烈的情感色彩,对微博言论的情感分析是获取用户观点态度的重要方法。许多学者都是将研究的重点集中在句子词性、情感符号以及情感语料库等方面,然而用户自身的情感倾向性并没有受到足够的重视,因此,提出了一种新的微博情感分类方法,其通过建模用户自身的情感标志得分来帮助识别语句的情感特征,具体地讲,将带有情感信息的微博语句词向量序列输入到长短期记忆网络(LSTM),并将LSTM输出的特征表示与用户情感得分进行结合作为全连接层的输入,并通过Softmax层实现了对微博文本的情感极性分类。实验表明,提出的方法UA-LSTM在情感分类任务上的表现超过的所有基准方法,并且比最优的基准方法MF-CNN在F1值上提升了34%,达到091。

Abstract:

Micro-blog's speech often has strong sentimental color, and the sentiment analysis of Micro-blog's speech is an important way to get users' opinions and attitudes Many researchers conduct research via focusing on the parts of speech (POS), emotion symbol and emotion corpus This paper proposes a novel method for Micro-blog sentiment analysis, which aims to identify the sentiment features of a text by modeling user sentiment tendency Specifically, we construct a sentiment information embedded word embedding sequence, and input it into a long short term memory (LSTM) model to get a sentiment embedded output representation Then we merge both the user sentiment tendency score and the output representation of LSTM, and use it as the input of a fully connected layer which is followed by a softmax layer to get the final sentiment classification result The experiment shows that the performance of our proposed method UA-LSTM is better than all the baseline methods on the sentimental classification task, and it achieves the F1-score up to 091, with an improvement of 34% over the best baseline method MF-CNN
