[Sigmetrics] Identification of long-term concept-symbols among citations

[T V Gopal]

Dear Prof. Loet Leydesdorff,

Thank you for an interesting paper.

At times, the seminal work may be in a seemingly unrelated domain. How is
it reflected / factored in your paper ?

Can documents be clustered in terms of common intellectual histories?


Jordan A. Comins and Loet Leydesdorff



"Citation classics" are not only highly cited, but also cited during
several
decades. We test whether the peaks in the spectrograms generated by
Reference Publication Years Spectroscopy (RPYS) indicate such long-term
impact by comparing across RPYS for subsequent time intervals. Multi-RPYS
enables us to distinguish between short-term citation peaks at the
research
front that decay within ten years versus historically constitutive
(long-term) citations that function as concept symbols (Small, 1978).
Using
these constitutive citations, one is able to cluster document sets (e.g.,
journals) in terms of intellectually shared histories. We test this
premise
by clustering 40 journals in the Web of Science Category of Information
and
Library Science using multi-RPYS. It follows that RPYS can not only be
used
for retrieving roots of sets under study (cited), but also for algorithmic
historiography of the citing sets. Significant references are historically
rooted symbols among other citations that function as currency.
