Database offers on-the-fly results.

A new Internet database lets users generate on-the-fly citation statistics of published research papers for free. The tool also calculates papers' impact factors using a new algorithm similar to PageRank, the algorithm Google uses to rank web pages. The open-access database is collaborating with Elsevier, the giant Amsterdam-based science publisher, and its underlying data come from Scopus, a subscription abstracts database created by Elsevier in 2004.
The SCImago Journal & Country Rank database was launched in December by SCImago, a data-mining and visualization group at the universities of Granada, Extremadura, Carlos III and Alcalá de Henares, all in Spain. It ranks journals and countries using such citation metrics as the popular, if controversial, Hirsch Index. It also includes a new metric: the SCImago Journal Rank (SJR).
The familiar impact factor created by industry leader Thomson Scientific, based in Philadelphia, Pennsylvania, is calculated as the average number of citations by the papers that each journal contains. The SJR also analyses the citation links between journals in a series of iterative cycles, in the same way as the Google PageRank algorithm. This means not all citations are considered equal; those coming from journals with higher SJRs are given more weight. The main difference between SJR and Google's PageRank is that SJR uses a citation window of three years. See Table 1

A very common workflow is to index some data based on its embeddings and then given a new query embedding retrieve the most similar examples with k-Nearest Neighbor search. For example, you can imagine embedding a large collection of papers by their abstracts and then given a new paper of interest retrieve the most similar papers to it.
TLDR in my experience it ~always works better to use an SVM instead of kNN, if you can afford the slight computational hit
Democracy was dealt a major blow in 2020. Almost 70% of countries covered by The Economist Intelligence Unit’s Democracy Index recorded a decline in their overall score, as country after country locked down to protect lives from a novel coronavirus. Find out more in our recent report.

Researchers believe that comparing products, rather than rating them on an absolute scale, will lead to algorithms that better predict customers’ preferences. ----------------- http://horicky.blogspot.com/2011/09/recommendation-engine.html

Ein Rangkorrelationskoeffizient ist ein parameterfreies Maß für Korrelationen, das heißt, er misst, wie gut eine beliebige monotone Funktion den Zusammenhang zwischen zwei Variablen beschreiben kann, ohne irgendwelche Annahmen über die Wahrscheinlichkeitsverteilung der Variablen zu machen.
Anders als Pearsons Korrelationskoeffizient benötigt er nicht die Annahme, dass die Beziehung zwischen den Variablen linear ist. Der Rangkorrelationskoeffizient ist robust gegenüber Ausreißern.
Es gibt zwei bekannte Rangkorrelationskoeffizienten: Spearmans Rangkorrelationskoeffizient (Spearmans Rho) und Kendalls Tau. Während Spearmans Rho von einer Gleichabständigkeit (= Äquidistanz) der Skalenwerte/Ränge ausgeht, basiert Tau rein auf ordinaler Information. Das ist z. B. bei den oft genutzten Likert-Skalen von Bedeutung. Zur Ermittlung der Übereinstimmung zwischen mehreren Beobachtern (Interrater-Reliabilität) auf Ordinalskalenniveau wird dagegen auf den mit den Rangkorrelationskoeffizienten verwandten Konkordanzkoeffizient W nach Kendall zurückgegriffen.
