Research on a New Weakening Buffer Operator of Investment Forecasting for Constructing Digital Libraries

Digital libraries are an important milestone in the development of libraries.An intimate knowledge of the developing law of digital libraries is of great significance to accurate prediction of funds for library construction and to the improvement of regional libraries.In order to increase the prediction accuracy of future values of systematic characteristic data sequences,this paper analyzes the flaws of the existing achievements of research into buffer operators.According to the principle of "new information taking priority",a new weakening buffer operator(NWBO) is built and compared with the existing weakening buffer operators in weakening effects.Finally,the validity of NWBO is tested by studying a case of construction funds of a digital library.The results show that the modeling accuracy is dramatically increased when the sequence of funds for constructing digital libraries which are influenced by disturbance factors is weakened by the NWBO.
