“…The main directions for microblog data analysis are as follows: topic-event analysis (Ritter et.al, [14]; Yang et.al, [15]), sentiment analysis (Bollen et.al, [16]; Thewall et.al, [17]), information retrieval and recommendation (Spina et.al, [18]; Yao et.al, [19]), user network relation analysis (Recuero et.al,[20]; Yin et.al, [21]), information dissemination (Naaman et.al, [22]; Xue et.al, [23]), impact analysis (Ding et.al, [24]; Steeg and Galstyan, [25]), and analysis of intra-urban human mobility (Li et.al,[26]; Wu et.al, [27]). Li et al [9] constructed China's intercity geo-social network based on the relations among Sina Microblog (SM) users and revealed that China's intercity social network was substantially imbalanced with significant global heterogeneity and local heterogeneity. Zhen et al [4] analysed China's urban network hierarchy from the perspective of the microblog social network space and identified the centre cities of China's urban network and their clustering distribution.…”
