摘要 [目的/意义]从融合主题的视角提出一种更为全面地揭示和描述学科主题的科学知识结构模型,并验证模型系统内部的耦合性和协同性。[方法/过程]基于系统论、相关性原理和三螺旋理论提出一种科学知识结构融合主题表征方法,定义“主题指纹”概念并进行模型构建;以《中国图书馆分类法》二级目录体系中“信息&科学”“计算机技术”和“自动化”三个类别分支为入口,选取数据挖掘、机器学习、自然语言处理作为实证案例,运用熵值方法量化科学知识结构模型系统内部的耦合度和协同度。[结果/结论]以上所构建的融合主题的科学知识结构模型形成了融合三元主题来揭示和描述知识结构的新思路,由文献主题指纹所映射的知识系统各要素之间具有耦合特征,各要素之间的相互作用共同促进知识系统协同演化。 [Purpose/significance]From the perspective of integrating subjects,this paper proposes a scientific knowledge structure model for knowledge evolution analysis,interprets and verifies the coupling and synergy features of the model.[Method/process]Firstly,this paper proposes a method of integrating subjects to represent knowledge structure based on system theory,relativity theory and Triple-helix theory,defines the concept of“subject fingerprint”to construct the model.Secondly,this paper chooses three cases which are data mining,machine learning and natural language processing from the three categories of“Information&Science”“Computer Technology”and“Automation”in the secondary directory system of Chinese Library Classification,aiming to quantitative analysis of its degree of coupling and synergy by entropy method.[Result/conclusion]The model of subject knowledge structure constructed above forms a new idea of integrating three-dimensional subjects to reveal and describe the structure of subject knowledge.The knowledge system mapped by the“subject fingerprint”of publications has coupling characteristics,and the interaction between the elements promotes synergistic evolution of knowledge system.
