Tracing scientific influence
Scientometrics is the field of quantitative studies of scholarly activity. It
has been used for systematic studies of the fundamentals of scholarly practice
as well as for evaluation purposes. Although advocated from the very beginning
the use of scientometrics as an additional method for science history is still
under explored. In this paper we show how a scientometric analysis can be used
to shed light on the reception history of certain outstanding scholars. As a
case, we look into citation patterns of a specific paper by the American
sociologist Robert K. Merton.Comment: 25 pages LaTe
The Evolution of the Science Citation Index
El Science Citation Index (SCI) va ser proposat fa més
de 50 anys per facilitar la disseminació i recuperació de literatura
científica. El seu cercador era únic pel fet de basar-se en una
recerca per cites, però no va ser àmpliament adoptat fins que
va estar disponible en la xarxa en l'any 1972. El Journal Citation
Reports, que apareix com a conseqüència d'aquest en
1975, incloïa a més una classificació basada en el factor d'impacte.
No era comú utilitzar els factors d'impacte fins a fa una
dècada quan van començar a ser usats com una alternativa
per a calcular les freqüències esperades de cites a articles publicats
recentmentuna aplicació molt polèmica de la cienciometria
com eina per avaluar institucions i científics. L'inventor
de l'SCI, i la seva base de dades companya, l'SSCI, examinarà
la seva història i discutirà el seu ús més recent en la visualització
gràfica de microhistories de temes acadèmics. Mitjançant
HistCite, un programari patentat per a l'anàlisi historiogràfic algorítmic,
es parlarà sobre la genealogia del descobriment de
Watson-Crick de la estructura de la doble hèlix del DNA i la
seva relació amb el treball de Heidelberger, Avery i altres.The Science Citation Index was proposed over 50
years ago to facilitate the dissemination and retrieval of scientific
literature. Its unique search engine, based on citation
searching, was not widely adopted until it was made available
online in 1972. Its by product, Journal Citation Reports, became
available in 1975 and included its rankings by impact
factor. Impact factors were not widely implemented until about
a decade ago, when they began to be used as surrogates for
expected citation frequencies for recently published papersa
highly controversial application of scientometrics in evaluating
scientists and institutions. Here, the inventor of both the SCI
and its companion, Social Sciences Citation Index, review the
history of these instruments and discusses their more recent
use in graphically visualizing microhistories of scholarly topics.
In an example thereof, the patented HistCite software for algorithmic
historiographic analysis is used to follow the genealogy
of the Watson-Crick discovery of the double-helix structure of
DNA and its relationship to the work of Heidelberger, Avery,
and others

An evaluation of Bradfordizing effects
The purpose of this paper is to apply and evaluate the bibliometric method Bradfordizing for information retrieval (IR) experiments. Bradfordizing is used for generating core document sets for subject-specific questions and to reorder result sets from distributed searches. The method will be applied and tested in a controlled scenario of scientific literature databases from social and political sciences, economics, psychology and medical science (SOLIS, SoLit, USB Köln Opac, CSA Sociological Abstracts, World Affairs Online, Psyndex and Medline) and 164 standardized topics. An evaluation of the method and its effects is carried out in two laboratory-based information retrieval experiments (CLEF and KoMoHe) using a controlled document corpus and human relevance assessments. The results show that Bradfordizing is a very robust method for re-ranking the main document types (journal articles and monographs) in today’s digital libraries (DL). The IR tests show that relevance distributions after re-ranking improve at a significant level if articles in the core are compared with articles in the succeeding zones. The items in the core are significantly more often assessed as relevant, than items in zone 2 (z2) or zone 3 (z3). The improvements between the zones are statistically significant based on the Wilcoxon signed-rank test and the paired T-Test
