        China National Knowledge Infrastructure (CNKI) CNKI 1.0 CNKI 2.0

        • The concept of National Knowledge Infrastructure (NKI) was put forward by the World Bank’s 1998 World Development Report. In March 1999, with the general goal of fully opening up information channels in all aspects of knowledge production, dissemination, diffusion and utilization, and building an exchange and cooperation platform that supports knowledge innovation, learning and application in various industries across the country, Wang Mingliang proposed the construction of China National Knowledge Infrastructure project, which was listed as a key project of Tsinghua University.
        • CNKI 1.0 is an important transformation from document information services to knowledge services after the completion of the basic project of "China Knowledge Resources Database". The goal of CNKI1.0 is to conduct systematic and customized knowledge organization for the knowledge needs of specific industries, construct the "Knowledge Network Node" based on the internal relevance of content, and dig for the knowledge elements and their associated relationship based on Knowledge discovery。It represents the industrial strategic development direction of CNKI in serving knowledge innovation and knowledge learning, and supporting scientific decision-making.
        • After CNKI 1.0 was basically completed, CNKI has fully summarized the experience of industry knowledge services in the past five years. With the full application of big data and artificial intelligence technology to create a knowledge innovation service industry as a new starting point, CNKI project has entered the 2.0 era. The goal of CNKI2.0 is to deepen the CNKI1.0 knowledge service which based on the integration of public knowledge to integrate with the process and results of knowledge innovation in various industries and institutions through more precise, systematic and complete explicit management and tacit knowledge management in embed work and learning process in order to provide a collaborative research platform that supports problem-oriented knowledge services and stimulates group wisdom. Its important signs are the establishment of the "World Knowledge Big Data (WKBD)", the establishment of National Knowledge Infrastructure (NKI) that makes full use of the "World Knowledge Big Data" for internal and external brain collaborative innovation and collaborative learning, and the launch of the "Knowledge Innovation Service Project for Various Industries", all-round service for the construction of China's world-class scientific and technological journals and the co-construction of the "Double First-class Digital Library".
