EM clustering – Expectation Maximization (EM) clustering nodes based on various attributes such as citations, citation half-life, and betweenness centrality. The use of temporal attributes can help the visualization of emerging trends.
Citation – an instance that a publication references to another publication.
Citation half-life – the number of years that a publication receives half of its citations since its publication.
Citation tree-rings – outwards growing rings of a node to depict its time series of citations. The thickness of a ring is proportional to the citations in the corresponding year.
0. Glossary
Betweenness centrality – a metric of a node in a network that measures how likely an arbitrary shortest path in the network will go through the node.
MeSH terms – Medical Subject Heading terms are a set of controlled vocabulary compiled by the National Library of Medicine. CiteSpace shows MeSH terms assigned to nodes if there are matches in PubMed.
Co-citation – an instance in which two items, such as authors, documents, or journals, that are cited by a publication.
Color map – a spectrum of colors used by CiteSpace to depict temporal order of observations.
Pivotal points – see Turning points.
Publication types – study design types extracted from PubMed for clinical trial studies, including meta-analysis and randomized clinical trials.
Pathfinder network scaling – a network scaling algorithm that removes links that violate triangle inequality conditions so as to simplify a network by retaining salient links and paths only.
