摘要
被引频次是科技论文的重要评价指标,但因为引用同一化的问题,需要矫正使用被引频次评估带来的偏差。本文以自然语言处理领域论文的引用极性为数据,从施引文献的角度出发,研究了正面引用和中性引用论文的影响力差别,以及不同引用原因下,正面引用论文的影响力差别。进一步探讨了影响作者引用极性的施引因素。利用非参数检验和逻辑回归等统计推断方法比较发现,正面引用论文的影响力明显高于中性引用论文的影响力,且正面引用的不同引用原因中,应用类型的论文影响力更大;施引位置和引用长度对引用极性有较大的影响,而引用强度和参考文献个数对极性没有影响。本文的研究结论为进一步丰富引文分析理论和细化科技质量评价策略提供了有益的改革思路。
Citation frequency is an important evaluation index for scientific papers,but because of the issue of citation homogeneity,the deviation of citation frequency must be corrected.Based on data regarding citation polarity of natural language processing papers,this paper studies the influence of the differences between positive and neutral citations as well as between differently motivated positive citations.Furthermore,it discusses which factors influence an author's citation polarity.Using a nonparametric test,logistic regression,and other statistical inference methods,the study reveals that the influence of positive citations is significantly higher than that of neutral citations,and among the different reasons for positive citations,the influence of“applied”papers is greater.Furthermore,the position of the citation and the length of the citation sentence have a great influence on the citation polarity,but the citation intensity and the number of references have no influence on this polarity.This study's findings provide useful reform suggestions for further enriching citation analysis theory and refining evaluation strategies for technology quality.
