Abstract: Network properties are studied in the perspective of member correlation.Firstly，a correlation computing algorithm called Ad-Ch algorithm is introduced.The advantages and disadvantages of Ad-Ch algorithm are analyzed through experiments.Subsequently，a new correlation computing algorithm called disjoint paths weight accumulating algorithm is proposed.Finally，experiments are conducted to verify the performances of disjoint paths weight accumulating algorithm.Disjoint paths weight accumulating algorithm is proved to be effective in correlation computing by analyzing the results of the experiments.
