摘要
[目的/意义]针对论文颠覆性指数受参考文献数量及其重要程度差异的影响问题,改进颠覆性指数算法,以便更有效地区分突破性论文和其他高被引论文,科学合理地反映论文的突破性。[方法/过程]结合参考文献在焦点论文全文中对应的引文内容的全文本特征——引文目的和引文极性,筛选出在研究内容上与焦点论文相关的重要参考文献,围绕重要参考文献,修改颠覆性指数计算公式分子和分母,进而改进论文颠覆性指数。[结果/结论]研究发现,改进后的颠覆性指数使突破性论文更显著地区分于其他高被引论文;利用改进后的颠覆性指数,可从批量的高被引论文中准确识别更多的突破性论文。
[Purpose/Significance]To address the issue of disruptive index of papers being influenced by the number and importance of references,the improvement of disruptive index algorithm can distinguish breakthrough papers from other highly cited papers and reflect the breakthrough of papers more effectively.[Method/Process]The citation contents corresponding to the references in the focus paper,and their citation purpose and polarity are used to choose important references.The disruptive index algorithm is improved by revising the numerator and denominator in the formula based on important references related to the study of the focal paper.[Result/Conclusion]It finds that the improved disruptive index can more significantly distinguish breakthrough papers from other highly cited papers.More breakthrough papers can be accurately identified by the improved disruptive index from the group of highly cited papers.
