摘　　要：面对日益丰富与多介质的数字资源,跨媒体检索正成为图书馆为用户提供集成服务的工作重点。本文基于语义关联四大维度,依据数字资源跨媒体语义关联检索的实现机理,构建了图书馆数字资源跨媒体语义关联检索实现模型,阐述了模型中资源整合、语义分析与提取、语义关联挖掘、跨媒体本体构建、跨媒体语义检索算法、用户检索界面等模块的紧密耦合关系。该模型涉及资源体系建设、语义关联挖掘技术、检索算法等诸多因素,因而仍需进一步优化保障要素。In the face of increasingly abundant and multi-media digital resources, cross-media semantic association retrieval is becom- ing the focus of library＇s integrated services for users. Based on four dimensions of semantic association, relying on the realization mechanism of cross-media semantic association retrieval, this paper constructs the cross media semantic retrieval model. It elaborates resource consolidation, semantic analysis and extraction, semantic association mining, cross-media ontology construction, cross-media semantic retrieval algorithm, users retrieval interface module of the model tightly coupled. It needs to point out that this model in- volves many factors, such as resource system construction, semantic association mining, retrieval algorithm and so on, needs further optimize the guarantee elements.
