Abstract: 【Purpose/significance】In order to reveal and sort out the research status of cognitive computing at home and abroad and its
application in the field of library and information【. Method/process】Using CiteSpace visualization software, this paper comprehensively combs the discipline distribution and research hotspots of cognitive computing at home and abroad from the perspective of literature metrology and comparative analysis, and provides relevant suggestions on the application status and future practical application of cog? nitive computing in the field of Library and information.【Result/conclusion】The findings are as below: The discipline distribution of domestic cognitive computing research presents an interdisciplinary and multidisciplinary form. The research hotspots of common con? cern at home and abroad are artificial intelligence, machine learning, big data and granular computing. A hot research direction com? bining cognitive computing and graphic intelligence has been formed in China, which is mainly used in information retrieval and analy? sis, big data processing and knowledge discovery, intelligent human-computer interaction and academic paper evaluation【. Innovation/limitation】Using scientific measurement tools, this paper systematically combs the research status of cognitive computing at home and abroad, analyzes the application status in the field of graphics and information, and puts forward the application scenarios and uses inthe future.
