A Sentiment Analysis Method of Short Texts in Microblog

Traditional approaches to analysis the sentiment of short text don't consider the relationship between emotion words and modifiers and simply accumulate the sentiment of the sentence to obtain the sentiment of short text. In this paper, we show how to mitigate the problems through sentiment structure and the sentiment calculation rules. The sentiment structure is obtained from the dependency parsing with the relationship migration and modified distance, which makes a good contribution to understanding the sentiment of short text. The sentiment of short text is accumulated according to the different influence of relationships between the modifier and the emotion word and the contribution of each sentence to the sentiment calculation of short text. Experiment results validate the effective of the approach.
