摘要
关联聚合与关联分析技术可以提高数字资源的沟通与利用效率,优化数字资源使用环境,为数字图书馆知识发现服务提供新的技术支撑。基于关联聚合与关联分析的数字图书馆知识发现服务要遵循整体性与协调性、科学性与规范性、优先性与可持续性原则。从服务层、知识发现层、资源层构建知识发现服务体系,从做好数据集范围规划、分层次对元数据进行描述、建立关联立体的知识点体系实现数字图书馆知识发现服务。
Association aggregation and association analysis can improve the communication and utilization efficiency of digital resources,optimize the use environment of digital resources,and provide new technical support for the knowledge discovery services of digital libraries.Knowledge discovery services of digital libraries based on association aggregation and association analysis should follow the principles of integrity and coordination,scientificity and standardization,priority and sustainability.The knowledge discovery service system is constructed from the service layer,knowledge discovery layer,and resource layer,and knowledge discovery services of digital libraries can be realized by planning the scope of data set,describing metadata at different levels,and establishing a three-dimensional knowledge point system.
