我国知识图谱研究演进特征可视化分析

A Visual Analysis of Evolutional Characteristics of Knowledge Mapping in China

【目的/意义】从动态视角出发,通过对我国知识图谱研究的时空及主题演进的可视化分析,梳理其演进特征,提出发展建议,以促进该领域的可持续发展。【方法/过程】以CNKI期刊全文数据库为信息源,以"知识图谱"为主题检索相关文献。通过函数拟合识别我国知识图谱发展阶段,以k-core方法分析相关机构研究的持续性,以阶段新关键词梳理我国知识图谱在分析方法、分析工具、应用领域及数据来源四方面的演进情况。【结果/结论】我国知识图谱研究的发展进程可分为起步阶段、低速发展阶段和高速发展阶段,且现如今正处于加速发展期。相关研究机构分布较离散,且研究持续性差。分析方法、分析工具和数据来源较固定,应用领域广,且其发展呈现出多元化、交叉化、社会化、时代化和国际化的特点。

【Purpose/significance】From the dynamic perspective,through the visual analysis of the space-time and thematic evolution of knowledge mapping research in China, we summarized its evolutional characteristics and proposed development proposals in order to promote the sustainable development of this field.【Method/process】Using CNKI as the data resource, this paper retrieved related literatures about'knowledge mapping'. We identified the development stage of knowledge mapping in China through the function fitting, and analyzed the persistence of relevant institutions by the k-core method. With the new keywords in each stage, we untangled the evolution of analysis methods, analysis tools, application fields,and data sources of knowledge mapping research in China.【Result/conclusion】The development process of China’s knowledge mapping research can be divided into starting stage, low-speed development stage and high-speed development stage,and it is now in an accelerated development stage. Relevant research institutes are distributed more discretely and their research is less sustainable. Analysis methods, analysis tools, and data sources are relatively fixed, and the application field is wide and its development is diversification, cross-cutting, socialization, modernization and internationalization.
