摘要
文本挖掘与网络分析是知识发现的重要方式,结合已有研究,本文提出了一种基于时间拓展网络的知识发现方法。首先,通过阶段划分、关键词时间拓展网络构建、节点距离赋值、节点-弧关联矩阵,提取并进行最短路径的求解。然后,通过接近中心性的计算来确定各关键词的相对重要性,并与时间拓展网络中最短路径的组成节点予以匹配,从而确定知识发展过程中的重要路径。本文以1979—2018年24个信息管理领域重要期刊的43624篇文献为样本,将其按10年等间距划分为4个阶段,通过CiteSpace软件软件对文献的关键词进行提取与统计,采用基于时间拓展网络方法确定其知识演化最短路径。研究结果显示,信息管理研究的知识发展主要围绕管理、信息系统、创新、设计和实施5条主要路径延伸,彼此之间又通过技术、模型与方法、扩散、知识等内容相关联,从而形成了信息管理研究的知识网络。
Text mining and network analysis have become important tools for knowledge discovery. This study proposes a method based on time-expended network considering prior related research. First, through stage division and keyword time-expanded network construction, this study assigns arcs value and carries out calculation of node-arcs matrix to detect the shortest paths. Next, it ranks the relative importance of keywords based on the closeness centrality and discovers the main knowledge development paths by matching the nodes of shortest paths within time-expanded network. In addition, it takes 43,624 articles of 24 journals in the information management field from 1979 to 2018 as samples to check the fitness of this method. The development period is divided into four equal slices with 10 years, which is followed by extraction and statistical analysis of the keywords by CiteSpace software. The knowledge evolution paths are found based on the time-expanded network and nodes’ closeness centrality. The results show that the knowledge development of information management research mainly includes five main paths, such as management, information system, innovation, design, and implementation;these paths connect with each other through technology, model and method, diffusion and knowledge, etc.which formed the knowledge network of information management research.
