Abstract: Microblog is an important platform, from which people can obtain and transmit information, and also is important data source to analyze and grasp the public opinion. In order to grasp aerospace event's influence on public opinion, this paper carried out a study on aerospace microblog data sentiment analysis, via manual training data construction, feature designing and support vector machine(SVM) model training, we propose a method to judgment the aerospace microblogging is positive or negative. Experiment result show that, the method discussed in this paper get high precision and recall value, which verify the effectiveness of proposed method in aerospace microblogging sentiment analysis judgment.
