Metadata records duplicate detection and management of federated digital library are one of key issues to ensure metadata quality and improve federal retrieval services. Many duplicate record detection methods exist for conventional federated digital library, but they are computationally intensive and low accuracy and so on. This paper proposes an efficient duplication approach for a relatively large federated digital library based on improved N-Gram method. Simulation experimental results show that the method improve the performance of duplicate detection effectively, accelerate the rate of duplicate detection.
