- Abstract:

The objective in sentiment analysis is to analyze the sentiment tendency contained in subjective text. Most sentiment analysis methods deal with text only and ignore the information provided in the corresponding pictures. In this paper, we propose a multi-view microblog analysis method based on semantic features. Using latent semantic analysis, we map both the text and image features to the semantic space in the same dimensionality, and use SVM-2K to obtain and classify the respective semantic features. We conducted experiments by crawling text and pictures from popular microblogs. The results show that, by combining the semantic features of text and pictures, the sentiment classification result is better than that obtained using text or image features alone.
