Tóm tắt	Structural variation analysis (SVA), developed by Chaomei Chen in 2012, is a predictive bibliometric method that estimates the transformative potential of a newly published paper from how much it perturbs the existing structure of a field's literature. Building on the idea that scientific breakthroughs typically recombine previously disconnected bodies of knowledge, SVA represents a field as a baseline co-citation network and then measures the structural change a new paper introduces by adding the novel links implied by its reference list. Papers that forge boundary-spanning connections — bridging clusters that were formerly separate — are hypothesized to be more likely to attract future citations. Chen operationalized this with metrics such as the modularity-change rate, cluster linkage, and centrality divergence, and showed that they help predict a paper's eventual citation impact, giving the field an early, structural signal of potentially high-impact work.	Kleinberg burst detection identifies periods during which a feature in a document stream — a keyword, a phrase, or citations to a particular paper — suddenly surges in frequency, signaling an emerging topic or a moment of intense attention. Introduced by Jon Kleinberg in 2003 to find bursty structure in streams such as email and news, the algorithm models the arrival of events with an infinite-state automaton in which higher states correspond to faster emission rates. A burst is detected when the optimal explanation of the stream requires moving into a high-rate state, with a built-in cost that discourages spurious switching. In scientometrics the method has become a standard way to detect rising research terms and 'citation bursts' — papers or topics whose citation rate spikes — making sudden growth in the literature visible and datable.
