面向含时引文网络的论文现时影响力评价

Current impact evaluation of papers based on temporal citation network

【目的】构建基于含时引文网络的论文现时影响力评价模型,以体现科学引文网络中的动态时变特征对期刊论文影响力评价的影响。【方法】在LeaderRank算法的基础上进行改进,同时考虑节点新鲜度及邻居节点的数量和质量的作用,构建一个论文现时影响力评价模型。以1970—2013年有机发光二极管领域科学文献数据为实验对象,并且使用这些论文2014—2018年的被引频次作为验证数据,对所提模型的有效性进行验证。【结果】所构建的模型能够顾及网络中时间因素的影响,对论文现时影响力评价得出较为合理的结果。【结论】含时引文网络的论文现时影响力评价模型为期刊论文的影响力评价提供了一种新思路。

[Purposes]A paper current impact evaluation model of the temporal citation network is constructed to reflect the influence of the dynamic time-varying characteristics in the scientific citation network on the impact evaluation of journal papers. [Methods]Based on the LeaderRank algorithm,the current paper impact evaluation model was proposed,taking into account the role of nodes’ freshness and the number and quality of neighbor nodes. The scientific paper data in the field of organic light-emitting diodes from 1970 to 2013 were used as the experimental objects,and the citation frequency data of these papers from 2014 to 2018 were used as the validation data to verify the effectiveness of the proposed model. [Findings] The proposed method can consider the influence of time factor in the network,and get a reasonable result for the current impact evaluation of the paper. [Conclusions] The current impact evaluation model of citation network provides a new idea for the impact evaluation of journal papers.
