基于发现系统的资源调度知识库结构研究

Research on Structure of Resource Scheduling Knowledge Base Built upon Discovery System

图书馆的资源调度能力是随着信息组织与信息管理工具的演进而发展的。在情景敏感的调度要求下资源调度知识库呼之欲出。资源调度知识库是发现系统下的新型资源目录系统,是原有资源调度模块的继承与发扬和联合目录系统中共享思想的创新型运用。本文采用分数加权计算与分数排序的思想,通过资源特性和用户情景特性的匹配关系来说明该知识库的工作原理,并设计出支持知识库情景敏感调度实现的物理结构和逻辑结构,分析了在资源调度知识库结构构建过程中需要解决的问题。重点关注了知识库所具有的数据类型和表格类型、表格之间的逻辑关系、表格之间的数据传递及调度工作流程、每张表格在物理结构上的存储位置等方面的细节。

The resource scheduling capability of library develops with the evolution of information organization and information management tools.The resource scheduling knowledge base is ready to emerge under the context sensitive scheduling requirements.The resource scheduling knowledge base is a new resource directory system beneath the discovery system,and it is the inheritance and development of the original resource scheduling module and the innovative application of shared ideas in the union directory system.This paper adopts the idea of weighted calculation and score ranking,and illustrates the working principle of the knowledge base by matching resource characteristics and user context characteristics.It also designs the physical structure and logical structure that support the realization of knowledge base context sensitive scheduling.The problems that need to be solved in the process of constructing the structure of resource scheduling knowledge base are analyzed.It focuses on details of the data types and table types of the knowledge base,logical relationships of the tables,data transfer and scheduling process of the tables,and storage location of the tables on the physical structure.
