摘　　要：为了提高数字图书馆信息共享空间服务能力,提出基于OGSA的数字图书馆信息共享空间服务模式构建方法。构建数字图书馆信息共享的节点分布模型,结合自适应寻优的方法对图书馆信息共享空间大数据进行分析,根据数字图书馆信息空间分布存储节点的分布特性,实现信息融合,构建数字图书馆信息共享空间服务信息特征检索模型,对数字图书馆信息共享空间服务信息特征进行检索,采用网格分块聚类分析方法,实现对数字图书馆信息共享空间服务模式下的特征聚类,结合OGSA实现数字图书馆信息共享空间服务模式优化构建。仿真结果表明,采用该方法进行数字图书馆信息共享空间服务模式设计的信息检索性能较好,语义识别能力较强,提高了数字图书馆信息共享服务水平。In order to improve the service capability of digital library information sharing space,a construction method of digital library information sharing space service mode based on OGSA is proposed.A node distribution model is constructed for digital library information sharing,the big data in the library information sharing space is analyzed with an adaptive optimization method,and information fusion is realized according to the distribution characteristics of the storage nodes of the digital library information space distribution,and a digital library Information sharing space service information feature retrieval model is built,build to retrieve the information characteristics of digital library information sharing space service information,using grid block clustering analysis method to realize the feature clustering under the digital library information sharing space service mode,combined with OGSA Realize the optimized construction of the information sharing space service mode of the digital library.The simulation results show that using this method to design the digital library information sharing space service mode has better information retrieval performance and strong semantic recognition ability,which improves the level of digital library information sharing services.
