摘要

[目的/意义] 为满足用户多粒度的知识需求,提出一种数字图书馆多粒度集成知识服务模式。[方法/过程] 首先对知识元的类型与描述规则以及不同类型知识元的实体对象结构加以定义;然后根据知识元抽取、标引和链接的方法,提出基于显性、隐性知识链接的多粒度知识集合集成方法;最后通过规范化分解用户提交的知识需求,构建"需求——知识——资源"三级映射,实现数字图书馆多粒度的集成知识服务模式。[结果/结论] 该方法将知识服务的控制单位从粗粒度的文献单元,深入到以知识元、知识元集合为单位的细粒度知识单元中,为用户提供不同粒度的知识资源。

Abstract

[Purpose/significance] The research aims to propose the multi-granularity integrated knowledge service model to meet the needs of multi-granularity knowledge.[Method/process] Firstly, we define the description method, types and entity structure of knowledge element. Secondly, we propose a method of knowledge organization based on explicit and tacit knowledge links, according to extraction, indexing and linking of knowledge element. Finally, we construct "demand-knowledge-resources" mapping to achieve the multi-granularity integrated knowledge service model, by decomposing the needs of user's knowledge.[Result/conclusion] This method makes the control unit of knowledge service from the coarse-grained literature unit to the fine-grained knowledge element or knowledge set, and provides users with multi-granularity knowledge resource.
