跨学科知识融入对学科知识体系扩展效应研究OA

[Purpose/significance]Under the context of New Liberal Arts construction,the resolution of many major scientific and techno-logical issues requires transcending traditional disciplinary boundaries.By identifying and integrating interdisciplinary knowledge,it becomes possible to grasp the direction of disciplinary development and predict emerging innovative trends.[Method/process]This study takes the full-text information of articles from six academic journals in China's library and information science(LIS)from 2017 to 2021 as its research object.Drawing on the kinetic energy theory from physics,it constructs a kinetic energy model for interdisciplinary knowl-edge integration from the dual dimensions of quoting scholars driving force and disciplinary attraction,and conducts empirical research.[Result/conclusion]The results indicate that the disciplinary gravitation coefficient can effectively quantify the gravitational effect of a dis-ciplinary knowledge system on interdisciplinary knowledge,helping to characterize the expansion effect of the peripheral boundaries of the disciplinary knowledge system from the perspective of kinetic energy.The study also reveals that the development of library and infor-mation science exhibits significant technology-driven and social management-oriented characteristics.In terms of knowledge categories,the expansion of the library and information science knowledge system is primarily driven by thematic concepts and technological meth-ods,while theoretical models are consistently sourced from sociology,management,and computer science.Indicator tools,however,face certain limitations due to their disciplinary attributes and adaptability factors.
