How To Count Citations If You Must
针对现有引用指标（如h指数）依赖直觉和粗略规则导致不良结论的问题，提出满足五个自然属性的欧几里得指数，即个人引用列表的欧几里得长度，实证表明其优于h指数。
Citation indices are regularly used to inform critical decisions about promotion, tenure, and the allocation of billions of research dollars. Nevertheless, most indices (e.g., the h-index) are motivated by intuition and rules of thumb, resulting in undesirable conclusions. In contrast, five natural properties lead us to a unique new index, the Euclidean index, that avoids several shortcomings of the h-index and its successors. The Euclidean index is simply the Euclidean length of an individual's citation list. Two empirical tests suggest that the Euclidean index outperforms the h-index in practice.
