图书馆数字资源跨媒体语义关联检索的实现模型及保障措施
|
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 becoming 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 involves many factors,such as resource system construction,semantic association mining,retrieval algorithm and so on,needs further optimize the guarantee elements.
