云检索系统是利用云计算的理念,对现有检索系统的一种改进。文章从云检索系统的理念设计着手,对云检索系统的概念、研究内容、系统要素等进行界定。利用系统分析和综合的方法,从狭义和广义两个角度构造了云检索的系统结构图,对结构图中的主要模块分别进行了介绍,指出系统结构图对云检索研究的意义,展望了云检索的研究方向。 Cloud retrieval system is the use of cloud computing concept, an improvement on the existing retrieval system. The article begins with the concept design of cloud retrieval system and defines the concept, research content and system elements of cloud retrieval system. By means of system analysis and synthesis, the system structure of cloud retrieval is constructed from the narrow and broad perspectives. The main modules of the structure diagram are respectively introduced. The significance of system structure drawing on cloud retrieval research is pointed out. Retrieve the research direction.
