New analysis features of the CRExplorer for identifying influential publications
presentation

Reference Publication Year Spectroscopy (RPYS) to publication sets
downloaded from Scopus or Web of Science. RPYS reveals quantitatively
which historical papers are of particular importance for a given
publication set. In this paper, we present some new advanced statistics
included in CRExplorer to identify and characterize cited references
(CRs) which have been influential across a longer period of time (i.e.,
many citing years). The indicators N_TOP50, N_TOP25, and N_TOP10 can be
used to find those CRs with (significantly) higher impact than
comparable CRs from the same publication year. Furthermore, CRExplorer
analyses the sequence of citations across many citing years to identify
specific types of citation distributions. For example, "hot papers" have
early, but not late impact. The new statistics are demonstrated using
all the papers published in the journal Scientometrics between 1978 and
2016. The analysis of the example dataset revealed, for example, that
the paper by Lotka (1926) entitled "The frequency distribution of
scientific productivity" belongs to the 10% most frequently cited
publications in 36 citing years. However, such papers are exceptions;
many publications show citation distributions which are characterized by
changes in citation impact intensities over the citing years.
