3、ness 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.中介中心性Burst terms single or multi-word phrases extracted from the title,abstract,or other fields of a bibliographic record and the frequency of the term bursts,i

4、.e.sharply increases,over a period of time.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

5、series of citations.The thickness of a ring is proportional to the citations in the corresponding year.Cluster view a network is visualized in a modified spring-embedder node placement algorithm.Co-authors authors who appear in the author field of the same bibliographic record.Co-citation an instanc

6、e 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.EM clustering Expectation Maximization(EM)clustering nodes based on various attributes such as citations,citation half-

7、life,and betweenness centrality.The use of temporal attributes can help the visualization of emerging trends.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 P

8、ubMed.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.Pivotal points see Turning points.Publication types study design types extracted from PubMed for clinical

9、trial studies,including meta-analysis and randomized clinical trials.Spotlight visualized networks rendered by fading out links that are not connecting pivotal points.Thresholds selection criteria used by CiteSpace items must have measures above threshold values to be included in modeling and visual

10、ization processes.极限Time slicing a divide-and-conquer strategy that divides a period of time into a series of smaller windows.时间片Time-zone view a restricted view in which the movement of nodes is limited to vertical time zones corresponding to the time of their publication.Turning points nodes of hi

11、gh betweenness centralities(1.00).Such nodes tend to be critical in network transitions from one time slice to another.1.Access/Obtain CiteSpaceTwo Ways to Run CiteSpace1.Java WebStartUsing Java WebStart ensures you are always using the latest version because the link always points to the most recen
