煤矿安全专家合作网网络特征分析

Characteristics of coal mine safety experts' cooperation network

从科学合作的视角出发,采用社会网络分析方法,借助UCINET分析工具,构建了煤矿期刊领域十六个科技文献的专家合著网络,在分析煤矿安全专家合作网的结构特征的基础上,对中国煤矿安全领域科学合作的状况加以描述,计算了合作网络的网络连通性、网络中间中心度、平均路径长度、网络密度等指标,刻画了煤矿安全专家合作网的网络节点及网络关系。发现煤矿安全专家合作网存在一个明显的最大连通子图,揭示了煤矿安全专家合作网的本质特征即具有小世界性及无标度特性。此外还以《西安科技大学学报》为例,运用"煤矿安全"或含"煤炭安全"的词语进行文献检索,确定了关键专家,运用知识图谱演化方法分析了相关专家的知识演化过程,为安全专家合作网络研究分析提供了崭新的视角。

From the perspective of scientific cooperation, taking social network analysis method and UCI- NET, the expert co-authorship network of 16 coal mine journals of science and technology document is constructed. Based on the structural characteristics of coal mine safety expert cooperation network, we e- laborated China＇ s coal mine safety scientific collaboration. At the same time, calculated the network con- nectivity of cooperation network, network center degree, average path length and network density index, depicting network nodes and network relationships of the mine safety expert cooperation network . It is found that there is a clear and obvious way to reveal the essential characteristics of coal mine safety ex- pert cooperation network, which is characterized by small world and scale free. Also Journal of Xi＇ an U- niversity of Science and Technology as an example, using the ＂coal mine safety＂ or with ＂coal mine safety＂for literature retrieval to determine the key experts, and knowledge mapping evolution method is applied to analysis of the relevant expert knowledge evolution, providing theoretical guidance for security experts cooperation network research and analysis.
