x-index：量化科学家科学影响力的奇妙新指标
x-index: a fantastic new indicator for quantifying a scientist's scientific impact
摘要：
h指数已成为量化科学家在各个科学领域的科学影响力的最流行指标。h指数定义为引用数大于或等于h的论文的最大数量，它平等对待每一个引用。然而，不同的引文通常来自不同的论文，具有不同的影响力和质量，而来自高影响力论文的引文比来自普通论文的引文更能体现对目标论文的认可。基于这一假设，我们提出了一个新的指标，称为x指数来量化一个科学家的科学影响力，只考虑来自有影响力的论文的引文。x指数定义为有影响力的引文数大于或等于x的最大数量的论文，其中每个有影响力的引文来自其作者的平均ACNPP（每篇论文的平均引文数）大于或等于x的论文。通过对APS数据集的分析，我们发现本文提出的x指数能够更好地区分物理学奖获得者和普通物理学家。
英文摘要：
h-index has become the most popular indicator for quantifying a scientist's scientific impact in various scientific fields. h-index is defined as the largest number of papers with citation number larger than or equal to h and it treats each citation equally. However, different citations usually come from different papers with different influence and quality, and a citation from a highly influential paper is a greater recognition of the target paper than a citation from an ordinary paper. Based on this assumption, we proposed a new indicator named x-index to quantify a scientist's scientific impact by considering only the citations coming from influential papers. x-index is defined as the largest number of papers with influential citation number larger than or equal to x, where each influential citation comes from a paper for which the average ACNPP (Average Citation Number Per Paper) of its authors larger than or equal to x . Through analysis on the APS dataset, we find that the proposed x-index has much better ability to discriminate between Physics Prize Winners and ordinary physicists.
