摘要

As the popularity of research on digital library is rapidly increasing on the Internet, technologies for digital resource management have become an important topic. This paper presents a system of Digital Resource Management Engine (DME) in CADAL digital library. The DME system consists of four modules: the duplication elimination module of the digital resource, the autocheck module of the digital resource, the information-extraction module, the backup module of the digital resource. By means of DME, raw digital data are transformed into fine ones, and manipulated effectively then. Moreover, the DME system builds up a foundation for further use of the digital resource such as knowledge-based services. The DME system provides a valuable reference for future digital library projects in China.
