The invention discloses a method for comprehensively sorting scientific literature entities based on a connective network, which comprises the following steps: (1) constructing a literature correlation network according to relationship among the literature entities; (2) setting initial sorting values of nodes in the literature correlation network and expressing the initial sorting values of the nodes as vectors v; (3) constructing a correlation matrix A of the literature correlation network; (4) performing normalization of row vectors and normalization of column vectors to matrixes respectively and setting the obtained matrixes to a matrix B and a matrix C respectively; (5) calculating v' equal to B multiplied by (C plus H) multiplied by vT; (6) calculating v' equal to dv'a minus 1; then adding 1 minus d to each element in v' so as to obtain the vector v new, and expressing each component of the vector v new as the current sorting value; and (7) calculating an absolute value of difference between the current sorting value and the old sorting value of each node, and finding the maximum value thereof; if the maximum value is greater than a threshold value, transferring v equal to v new into 5 for continuous iteration; otherwise, expressing each component of the vector v new as a final sorting value of each node and finishing the operation. The comprehensive sorting method overcomes defects in the prior sorting method, sorts the entities in the literature field according to various relationships existing in the literature world; in addition, the experimental result in the literature indicates that the comprehensive sorting method in the literature is more accurate than the prior sorting method.
