摘　　要：【目的/意义】采用当前方法检索信息知识时,存在检索效率低和查全率低的问题。为用户提供全面的检索,需设计效率更好的知识检索系统。【方法/过程】提出了基于元数据的信息知识组织智能检索系统设计方法,利用Agent实现人机交互层、信息处理层和信息收集层在检索系统中的交互,分析了存储管理模块、用户接口模块、搜索引擎和索引模块、通信管理模块、特征提取模块的主要功能,通过自适应路由机制、查询机制和自配置机制实现信息知识的检索,完成信息知识组织智能检索系统的设计。【结果/结论】实验结果表明,本文方法具有信息知识检索效率高和查全率高的优点。【Purpose/significance】When using current methods to retrieve information and knowledge, there are problems of low retrieval efficiency and recall ratio. To provide a comprehensive retrieval for users, it is necessary to design a new information and knowledge retrieval system with high efficiency.【Method/process】A design method of metadata-based intelligent retrieval system for information and knowledge organization is proposed in this paper. The interaction between human-computer interaction layer, information processing layer and information collection layer in the retrieval system is realized by using Agent. The main functions of storage management module, user interface module, search engine and index module, communication management module and feature extraction module are analyzed. Information and knowledge retrieval is realized by adaptive routing mechanism, query mechanism and self-configuration mechanism.【Result/conclusion】The experimental results show that this method has the advantages of high retrieval efficiency and recall ratio for information and knowledge.
