Tóm tắt	Citation distribution modeling studies the statistical shape of how citations are spread across papers and uses that shape to compare impact fairly across very different fields. The pivotal result, from Filippo Radicchi, Santo Fortunato, and Claudio Castellano in 2008, is that although raw citation distributions differ enormously between disciplines, they collapse onto a single universal curve once each paper's citations are divided by the average for its field and year. This relative indicator turns an unfair comparison, a mathematics paper against a biomedicine paper, into a fair one by asking how each paper performs relative to its own field's baseline. The universal curve is well described by a lognormal form, and related work has used Tsallis or stretched-exponential and discounted-cumulative formulations, giving scientometrics a principled statistical foundation for normalization rather than ad hoc field adjustments.	A Sleeping Beauty is a publication that goes almost unnoticed for many years and then, sometimes decades later, suddenly attracts intense citation attention. Anthony van Raan introduced the metaphor to scientometrics in 2004, reporting the first systematic measurement of how often such delayed-recognition papers occur and deriving an awakening-probability function. Qing Ke and colleagues made the concept operational at scale in 2015 with a parameter-free beauty coefficient that, unlike earlier fixed thresholds, lets any citation trajectory be scored on a continuum of how deeply and how long it slept before awakening. Detecting Sleeping Beauties matters because they show that immediate citation impact is an imperfect proxy for scientific value: some of the most consequential ideas, including foundational work later recognized with prizes, were premature for their time and lay dormant until the field caught up.
