基于Altmetrics指标和Burst强度的前沿探测方法研究——以光伏发电技术为例

Research on Frontier Detection Method Based on Altmetrics Index and Burst Intensity:Case Study of Photovoltaic Power Generation Technology

[目的/意义]将研究成果的社会影响力指标与学术影响力指标相结合来开展前沿探测研究,可以更充分地发掘科技前沿。[方法/过程]基于Altmetrics指标与Burst强度,将社会影响力与学术影响力相结合,构建了知识基础影响力加权评分指数,并在此基础上对研究前沿文献进行关键词共现分析,绘制了研究前沿关键词共现图谱,最后以光伏发电技术为例对其前沿研究主题进行了总结分析。[结果/结论]基于Altmetrics指标的研究前沿主题与基于Burst强度的研究前沿主题既有联系也有区别,基于两种指标开展的前沿探测研究可以为前沿探测方法的拓展提供新的思路。

[Purpose/significance]Conducting the frontier detection researches with the combination of social impact indicators and academic impact indicators can explore the scientific and technological frontiers more completely.[Method/process]Based on Alt-metrics index and Burst intensity􀆯the paper constructs weighted score index of basic knowledge impact with the combination of social im-pact and academic impact.And on this basis􀆯it analyses the keyword co-occurrence of frontier papers and plots a keyword co-occurrence graph.Finally􀆯taking photovoltaic power technology as an example􀆯the paper analyses and summaries the topics of frontier researches.[Result/conclusion]The results show that the research frontier topics based on Altmetrics index and Burst intensity have connections and differences􀆯and the frontier detection research based on the two indicators provides new ideas for the expansion of frontier detection method.
