摘　　要：为了提高资源整合系统在对海量图书情报信息分类时的并发性能和图书情报信息的类型匹配效果,文中设计一种基于元数据的图书情报信息资源整合系统。在硬件方面,设计SDRAM电路,选择型号为MT48LC4M16A2TG的SDRAM,为信息资源融合系统提供存储内存,将MAX3232芯片作为收发芯片保证系统可以接收不同类型的信息,进行RS 323总线电路设计,从而抑制噪声和其他干扰信息。在软件方面,根据元数据描述数字化图书情报信息设计项目配置表,采用DSpace的构建模式设计逻辑架构,设置信息采集交换规范,由此实现对图书情报信息资源整合系统的构建。实验结果表明,所提方法得到的MAE值和RMSE值更低,可见此次设计的系统在保证错误率的前提下有更好的图书情报信息分类匹配效果,为图书情报信息资源整合提供更高效的技术支持。A metadata⁃based resource integration system of library information is designed to improve the concurrent performance and type matching effect of the resource integration system in the classification of massive library information.In terms of hardware,SDRAM circuit is designed,the SDRAM⁃MT48LC4M16A2TG is selected to provide the storage memory for the information resource integration system,the MAX3232 chip is used as transceiving chip to ensure that the system can receive the different types of information,and RS323 bus circuit is designed to suppress noise and other interference information.In terms of software,the configuration table of design project for the digital library information is described according to metadata,the DSpace construction mode is adopted to design the logical architecture,and the specifications of the information collection and exchange are set.Thereout,the construction of resources integration system for library information is realized.The experimental results show that the MAE and RMSE values obtained by the proposed method are lower.It can be seen that the designed system has better information classification and matching effect of the library information on the premise of ensuring a certain error rate,and can provide more efficient technical support for the resources integration of library information.
