加權要素對合著關系網絡的影響研究
發(fā)布時間:2018-11-13 19:45
【摘要】:本文按照社會網絡關系的研究方法,根據合著強度、作者貢獻度和合著影響力等加權要素分別構建了3種合著網絡關系計算模型,并通過實證研究對比分析3種模型對應的合著關系網絡的網絡圖形、中心性、凝聚子群、核心—邊緣結構等內容,研究探討合著強度、作者貢獻度和合著影響力等加權要素對合著關系網絡的作用和影響。結果表明,不同加權要素的選擇對點度中心性和核心—邊緣結構影響明顯;對網絡圖形的結構沒有影響,對其連接的強度(連線粗細)有影響;對中間中心性、接近中心性和凝聚子群均沒有影響。
[Abstract]:According to the research method of social network relationship, according to the weighted factors such as coauthor's strength, author's contribution degree and coauthor's influence, this paper constructs three calculating models of coauthor's network relationship, respectively. And through the empirical research and comparative analysis of the network graphics, centrality, condensed subgroup, core-edge structure and so on of the three models corresponding to the coauthor relationship network, the paper discusses the coauthoring strength. The author's contribution and coauthor's influence on the coauthor's relationship network. The results show that the choice of different weighting factors has a significant effect on the vertex centrality and core-edge structure, has no effect on the structure of the network graphics, and has an effect on the connection strength (line thickness). It has no effect on the middle centrality, proximity centrality and condensed subgroups.
