Abstract:

【Purpose/significance】Knowledge exchange among different disciplines promotes the generation and innovation of new

methods, and knowledge exchange between knowledge retrieval field and other disciplines is an important way of self-development.

【Method/process】This paper analyzes the time characteristics of knowledge exchange, periodical citation relations and discipline char⁃

acteristics of the literature in the field of knowledge retrieval on CNKI through citation analysis and social network analysis methods.

【Result/conclusion】In terms of time, the use of relatively new literature is weak, and its value needs to be explored in a certain period

of time. Generally, scholars refer to this kind of citation as the phenomenon of "sleeping beauty". According to the overall subject net⁃

work, subgroups can be divided into library information science, computer information science and medical information science.

Among them, library information science has the most knowledge output and influence on other subgroups. In terms of discipline char⁃

acteristics, applied discipline is the "main power" in the process of domain knowledge exchange, basic discipline only plays the role of

"heuristic knowledge output".【Innovation/limitation】According to the relationship between citations, the journals published in litera⁃

ture are divided into disciplines, and the specific network characteristics of disciplines are analyzed by combining with the method of

social network analysis; the research limitation is that the number of cited journals is limited, and the characteristics of domain knowl⁃

edge exchange are not fully revealed.
