【Abstract】 This paper studies the method for establishing the literature obsolescence model based on neural network,discusses the basic ideas of the method and its algorithm implementation process,and makes the calculation through actual examples,and figures out the literature’s half-life period by using the established neural network model,and makes the comparison with traditional calculating method based on B-K model,showing that the algorithm,which is feasible for the literature obsolescence,has higher accuracy.更多还原
