In order to improve the effect of collection information management, this paper uses intelligent computer technology to build a cultural and creative element resource library based on the collection information management system. This paper optimizes the design of TPBF by analyzing the false positive rate of the two-stage Bloomfilter query algorithm, determines the use conditions of the new algorithm, and obtains the optimal parameters of the two-stage Bloomfilter query algorithm according to the model. Aiming at the limited improvement of the standard Bloomfilter algorithm and its extended algorithm to reduce the false positive rate, this paper proposes a two-stage Bloomfilter algorithm. Moreover, this paper analyzes the parameters when the algorithm achieves the optimal result, and then proves that the result achieved by the algorithm is consistent with the theoretical expectation through simulation experiments. The experimental research shows that the cultural and creative element resource library based on the collection information management system proposed in this paper can effectively improve the information processing effect of museum collections.
