Analysis And Application Of Knowledge Mapping Based On Complex Network

In the era of knowledge economy,knowledge has increasingly become the core factor that determines the competitiveness of individuals,enterprises and even the nation.With the development of information technology,network and globalization,more and more large and complex knowledge structure,research activities have undergone profound changes,using knowledge mapping technology research discipline development becomes more and more popular and achieved remarkable results.Most of the problems in knowledge mapping can be expressed in the form of network,and complex network theory has a significant advantage in describing the structure and relationship of complex systems and the evolution process of the system.Research methods in the research activities on the relationship network,citation network,knowledge map,knowledge dissemination model of complex networks can be combined with knowledge map,more in-depth analysis of research subject,knowledge base,research focus and research frontier,has important academic value and significance to our country theory and technology system practice research.The main work of this paper is as follows:(1)The basic knowledge of complex network and knowledge mapping are summarized and summarized,introduces the common measure of complex network and its connotation,four typical complex network model of the real world: small world network and scale-free network model,local world evolution model and evolution model of water rights.This paper expounds the basic conception and knowledge mapping object,theory and application,summarizes the method of multivariate statistical analysis,frequency analysis,citation analysis,citation analysis,social network analysis of the five common research methods,provides four can be used for the introduction of knowledge mapping tools.(2)Identify and introduces two kinds of construction of knowledge map of available data sources,data content and data acquisition.In this study,to reflect the body of knowledge in complex networks: innovation cluster and knowledge unit embodied in complex networks: knowledge activities with the description and analysis,introduces the hierarchical clustering algorithm and the analysis of the dissemination of knowledge evolution algorithm.Finally,given the overall design principles and scheme of knowledge map based on complex network.(3)The overall plan for reference,using Web of UAV technology in Science core collection as a data source,UAV research subject,knowledge base,research hotspots,trends and frontier knowledge map was constructed,the UAV technology is now in the rapid development of it has not yet formed a mature and stable stage of development innovation cluster and knowledge structure.Whether it is to expand the application of existing research or try to innovate,new methods,new applications have great potential for development.The two hotspots of UAV research are summarized as "economic UAV application" and "UAV programming control".
