A Public Opinion Classification Algorithm Based on Micro-Blog Text Sentiment Intensity: Design and Implementation

On the features of short content and nearly real-time broadcasting velocity of micro-blog information, the authors' lab constructed a public opinion corpus named MPO Corpus. Then, based on the analysis of the status of the network public opinion, it proposes an approach to calculate the sentiment intensity from three levels on words, sentences and documents respectively in this paper. Furthermore, on the basis of the MPO Corpus and HowNet Knowledge-base and sentiment analysis set, the feature words' semantic information is brought into the traditional vector space model to represent micro-blog documents.
