【摘要】：随着人类社会的不断发展,各种高新技术如雨后春笋般涌现,全球进入了知识经济时代。区别于农业经济时代和工业经济时代,知识经济时代中经济发展的最大推动力来自于知识。知识是人类智慧的结晶,它推动着人类社会的前进。顺应时代发展趋势,信息服务机构转型向知识服务发展成为必然趋势。要想提供知识服务,必须先对知识进行管理。知识链接是实施知识管理的有效方法和手段。本文沿用从理论到应用再到实证的线索对知识链接进行了系统研究。首先对知识链接的国内外研究现状进行分析,综合研究了目前已有的研究成果,并且进行了简短的述评,认为如何让知识链接的对象资源更加多样、让知识链接系统更加开放、让知识链接的质量更加优化是这一领域亟待解决的问题。然后对知识链接的概念、类型、产生、发展、特征、功能、原理、模型以及构建方式等相关理论进行了研究,认为知识链接是指一个知识单元与另一个知识单元之间的链接关系。它以知识单元之间的逻辑关联关系为客观基础,按照一定的规则将知识单元联系起来,根据特定的需求将知识单元进行排列组合,并且进一步构成系统的知识网络;从链接状态和链接对象两个维度对知识链接进行分类,按时间顺序整理了它的发展历程,分析了它的特征和功能,并且构建了知识链接的简易模型,还进一步阐述了知识链接的四步构建方法。以基础理论研究为基础,本文接下来对知识链接在网络知识服务中的应用理论问题进行了研究。对网络知识服务的概念和特征进行了简单分析,将网络知识服务理解为在互联网环境下进行的知识服务活动。将知识链接与网络知识服务结合起来进行研究,认为知识链接在网络知识服务中应用具有四大优势:知识对象描述模型一致、知识关联描述语义化、知识发现机制灵活和知识获取机制统一,这些优势使知识链接成为网络环境下知识服务的热点应用。目前将知识链接应用于知识服务的技术主要体现为语义web技术、网格技术、导航库技术、知识仓库技术等,应用模式主要有基于咨询服务的应用、基于web自主服务的应用和基于个性化定制服务的应用三种。同时对其应用原则和功能进行了分析。最后,以CNKI和WIKI为案例进行了实证分析,分析了其结构及知识链接的具体应用。
[Abstract]:With the development of human society, all kinds of high and new technologies have sprung up, and the world has entered the era of knowledge economy. Different from the age of agricultural economy and industrial economy, the biggest driving force of economic development in the era of knowledge economy comes from knowledge. Knowledge is the crystallization of human wisdom, it promotes the progress of human society. In line with the trend of development of the times, the transformation of information service institutions to knowledge services has become an inevitable trend. To provide knowledge services, knowledge must be managed first. Knowledge link is an effective method and means to implement knowledge management. This paper makes a systematic study on knowledge link from theory to application to empirical clue. First of all, this paper analyzes the current research situation of knowledge link at home and abroad, synthesizes the existing research results, and makes a brief comment on how to make the object resources of knowledge link more diverse and the knowledge link system more open. To optimize the quality of knowledge link is an urgent problem in this field. Then the concepts, types, generation, development, features, functions, principles, models and construction methods of knowledge link are studied. Knowledge link refers to the link relationship between one knowledge unit and another knowledge unit. It is based on the logical relation between the knowledge units, links the knowledge units according to certain rules, arranges and assembles the knowledge units according to the specific needs, and further forms the knowledge network of the system. This paper classifies the knowledge link from the two dimensions of link state and link object, arranges its development course in chronological order, analyzes its characteristics and functions, and constructs a simple model of knowledge link. Furthermore, the four-step construction method of knowledge link is further expounded. Based on the basic theory research, this paper studies the application theory of knowledge link in network knowledge service. In this paper, the concept and characteristics of network knowledge service are simply analyzed, and the network knowledge service is understood as the knowledge service activity under the Internet environment. This paper studies the combination of knowledge link and network knowledge service, and points out that the application of knowledge link in network knowledge service has four advantages: consistent description model of knowledge object, semantic description of knowledge association, and so on. Knowledge discovery mechanism is flexible and knowledge acquisition mechanism is unified. These advantages make knowledge link become a hot application of knowledge service in network environment. At present, the technology of applying knowledge link to knowledge service is mainly embodied in semantic web technology, grid technology, navigation database technology, knowledge warehouse technology and so on. There are three kinds of applications based on web and personalized services. At the same time, the application principle and function are analyzed. Finally, taking CNKI and WIKI as case studies, the structure and application of knowledge link are analyzed.
