【摘要】 运用知识组织的方法和原理,结合OA期刊资源库的建设需求,对OA期刊知识自动组织的系统进行设计,该系统分为知识组织工具、OA期刊资源收割、OA期刊知识自组织和OA期刊知识组织展示四部分。在该模式下,用学科分类法作为OA期刊知识组织体系,通过网络蜘蛛实现OA期刊资源的自动收割,通过分词处理、特征词选择和特征词权重计算实现OA期刊学科标引和知识组织,最后用导航目录树与元数据组织相结合的方式来展现OA期刊。更多还原

【Abstract】 Using the methods and principles of knowledge organization,incorporating OA repository requirements,the self-organizing system for OA journals knowledge is designed.The system has 4 parts such as knowledge organization tools,OA journals resource harvesting,OA journals knowledge self-organization and OA journals knowledge organization exhibiting.In this mode,with the subject taxonomy to build OA journals knowledge organization system,automatic harvesting OA journals resources through web spider,OA journals discipline indexing and knowledge organization achieved through word processing,feature word selection and feature weighting calculation.Finally,combination of navigation tree and metadata organization is used to exhibit the OA journals.更多还原
