“…A few scientometric studies are available for the philosophy of science [GEISLER, 2005] and mathematical logic [WAGNER-DÖBLER, 1997], the latter of which is the core in the philosophy of science. But they are not for the definition of science.…”

“…Recently, Wagner‐Döbler (1997) has shown that there are qualitative differences between the distributions of publications in journals over time. We applied the Mann‐Whitney test to the Mathematical Logic successive decades in Table 1.…”

The fields of informetrics and scientometrics have suffered from the lack of a powerful test to detect the differences between two samples. We show that the Mann-Whitney test is a good test on the publication productivity of journals and of authors. Its main limitation is a lack of power on small samples that have small differences. This is not the fault of the test, but rather reflects the fact that small, similar samples have little to distinguish between them.

“…There are numerous of examples of applications of Bradford law in various disciplines like natural sciences and social sciences (e.g. Wagner-Döbler, 1997;Peritz, 1990). This law seems to be a very robust and commonly appearing phenomenon in most of the current literature databases and bibliographies.…”

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 laboratorybased 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 TTest.
