摘　　要： 分析了2006—2010年图情类核心期刊相互引用网络节点度、中介度等两个拓扑测度及其变化,引入节点度指数、节点度活跃指数、节点度上升指数以量化期刊被引频次变化方向及其速率,引入中介度指数、中介度活跃指数、中介度上升指数以量化和比较期刊在被引网络中起中介作用的程度及其发展变化,最终得出各期刊的节点度评分、中介度评分及总分,以期有效评估期刊的影响力和发展前景。 The paper analyzes two topological measurements and their changes of node degree and betweenness degree in the cross-citation network of core journals on library and information sciences from 2006 to 2010, introduces node degree index, node degree active index and node degree rise index to quantify the changing direction and speed of the citied frequency of a journal, as well as introduces betweenness degree index, betweenness degree active index and betweenness degree rise index to quantify and compare the bridge role and development of a journal in cited network. Finally it gets node degree score, betweenness degree score and total score of each journal respectively to assess journal’s influence and development foreground effectively.
