摘要提出了一套对非结构化数据进行分析和检索系统的设计方案。采用分布式技术在windows平台上建立了一套以任务分发服务器为中心,运算终端为任务处理单元,带有反馈和容错机制的分布式数据检索系统。在给出系统模型和设计思想基础上,对各个功能部件进行了模块化设计、并对各模块故障进行了测试,结果表明,系统能够在部分模块出错的情况下稳定运行,能够满足在实际工作中的需求。

Abstract Authors propose a set of pairs of unstructured data analysis and retrieval system design. Use of distributed technology in the windows platform to establish a set of task-distribution server as the central task of computing the terminal processing unit, with feedback and fault-tolerant mechanism for distributed data retrieval system. In the given system model and design based on the idea of the various functional components of the modular design, and failure of each module was tested, results show that the system can go wrong in some cases the module stable operation to meet the actual work requirements.
