知識鏈接及其在網(wǎng)絡(luò)知識服務(wù)中的應(yīng)用研究
[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.
