摘    要:目的/意义]针对采用不同引证网络探测新兴趋势的问题,比较群体动力学方法用于直接引证网络和文献耦合网络上的效能差异。方法/过程]首先构建并分析直接引证网络、文献耦合网络和同被引网络的特征,然后基于群体动力学方法对文献耦合网络进行实证研究。结果/结论]对比以往的研究结果发现:群体动力学方法作用于直接引证网络进行新兴趋势的预测结果较基线方法为好,而在文献耦合网络中预测的效果并不比基线方法更佳。

关 键 词:引证网络  引证分析  文献耦合  群体动力学  新兴趋势

Abstract:Purpose/significance] This paper compares the performance of direct citation network and bibliographic coupling network for detecting emerging trends with collective dynamics method. Method/process] First, we analyzed the characteristics and the difference on emerging trends detection of three kinds of knowledge networks:direct citation, bibliographic coupling and co-citation network. Then, an empirical study on bibliographic coupling network was performed based on the emerging trends detection model of collective dynamics. Result/conclusion] Compared with previous studies, it is found that the prediction result of collective dynamics method on the direct citation network is priority to the result of baseline method on the same network, but in terms of the bibliographic coupling network, the collective dynamics method shows no priority to the baseline method.
Keywords:citation network  citation analysis  bibliographic coupling  collective dynamics  emerging trends detection
