Characteristics Of Knowledge Diffusion On Big Data In The Foreign And Domestic

Knowledge diffusion is the core of knowledge production, playing an important role in the inheritance and innovation of knowledge. Inera of Big Data, scientific research institution has abundant research on it, arising a large number of excellent scientific research achievement. In this setting,exploring foreigncharacteristics of knowledge diffusion from the discipline, author, keywords based on WOS;elaborating domestichumanitycharacteristics of knowledge diffusion from the discipline, journal, institution, keywords based on CSSCI in CNKI.Measuring knowledge diffusion of discipline from intensity and extent;buildingauthor cooperationnetworks, journal citation networks,institutioncitation networks, keywords co-occurrence network, evaluating them fromdensity, centrality, cohesive subgroups analysis, core-peripheral structure by virtue of Ucinet, using Netdraw to display.Disscussing knowledge diffusion characteristics on foreign Big Data,knowledge diffusion breadth has relatively stable characteristics in discipline angle, knowledge diffusion has relatively closedcharacteristics from authors cooperation, having nodes cluster fromresearch hot spots. Elaborating knowledge diffusion characteristics on domestic humanity Big Data, knowledge diffusion breadth has relatively stable state after criticalpoint, knowledge difusion has relatively closedcharacteristics from inter-citation journals and institutions, Knowledge diffusion nodes are relatively concentrated from research topic. Generally speaking, Big Data research belongs to the emerging field, relevant subjects need to strengthen exchanges, learn about their own research trends, promoting the knowledge diffusion, to improve the efficiency of knowledge utilization efficiency.
