Abstract

This paper explores the feasibility of predicting users' retweeting behaviour and ranks the influencing features affecting that behaviour. The four first-dimension features, namely author, text, recipient and relationship are extracted and split into 39 second-dimension features. This study then applies support vector machine (SVM) to build the prediction model. Data samples extracted from Sina Microblog platform are subsequently used to evaluate this prediction model and rank the 39 second-dimension features. The results show the recall rate of this model is 58.67%, the precision rate is 82.19%, and the F1 test value is 68.46%, which show that the performance of the prediction model is highly satisfactory. Moreover, results of ranking indicate four features affect retweeting behaviour of users: the active degree of microblog author, the similarity of interests between the author and the recipient, the active degree of microblog recipient and the similarity between the theme of microblog and the recipient's interest.
