【摘要】Evaluation of the node importance is limited by single measure in existing literature, such as node degree, close-ness centrality, and betweenness centrality. Hence in this paper, the importance of the nodes in networks was ranked in an inte-grated fashion. A multi-attribution method was developed to identify important nodes more reasonably. Such an integrated multi-attribution evaluation method was applied to a keywords network of a specific school in material subject. The proposed method was compared with the frequency statistics and single-attribution methods, which shows the efficiency and advantages of multi-attribution method.%针对现有的复杂网络节点重要性的评价指标,如度、接近中心性和介数等为单一评价指标存在的局限性问题,构建了一种多属性决策的节点重要性综合评价方法。并用于探讨关键词同现网络节点的重要性,且与词频统计及单指标判断方法进行分析比较,探讨其中差异,实验验证了该方法的有效性。 【总页数】4页(461-464)
