Abstract：This paper builds the adjacent matrix based on the retweet relationship in micro-blogging to find the opinion leaders through improved HITS algorithm. Then a net of opinion leaders is built based on the relationship of retweet to prove the efficiency of the improved algorithm and to analyze the function of opinion leaders. The research shows that the improved HITS algorithm can find the opinion leaders effectively. The hub of an opinion leader is highly positive correlated with the amount of his fans. According to the analysis of the net of opinion leader, the authors find that the opinion leaders play important roles in the key nodes,and their function is not weakened by the increasing of information sources in the micro-blogging.
