指出科学合作网络中节点重要性鉴别通常是利用社会网络分析中的节点程度中心性或中介中心性来进行。这类指标并未考虑科学合作网络中的引文特性,因而并不能完全体现节点在合作网络中的重要性。比较和分析科学合作网络中各种节点影响力指标,并在Brner提出的引用强度指标基础上进一步提出节点合作收益指标,最后以禽流感合作网络为例评测和分析科学合作网络中具有重要意义的节点。 It is pointed out that the importance identification of nodes in scientific cooperation networks is usually made by using the degree of centrality or intermediary center of nodes in social network analysis. Such indicators do not take into account the citation features in scientific cooperation networks and therefore do not fully reflect the importance of nodes in cooperative networks. Compare and analyze the influence indexes of all kinds of nodes in the scientific cooperation network, and further put forward the index of cooperation benefits of nodes based on Brner’s reference strength index. Finally, taking bird flu cooperation network as an example, it is important to evaluate and analyze the scientific cooperation network Meaning of the node.
