Caveats for the Use of Citation Indicators in Research and Journal Evaluations
TLDR
The assumption that citation and publication practices are homogenous within specialties and fields of science is invalid and the delineation of fields and among specialties is fuzzy.Abstract:
Ageing of publications, percentage of self-citations, and impact vary from journal to journal within fields of science. The assumption that citation and publication practices are homogenous within specialties and fields of science is invalid. Furthermore, the delineation of fields and among specialties is fuzzy. Institutional units of analysis and persons may move between fields or span different specialties. The match between the citation index and institutional profiles varies among institutional units and nations. The respective matches may heavily affect the representation of the units. Non-ISI journals are increasingly cornered into "transdisciplinary" Mode-2 functions with the exception of specialist journals publishing in languages other than English. An "externally cited impact factor" can be calculated for these journals. The citation impact of non-ISI journals will be demonstrated using Science and Public Policy as the example.read more

hg-index: a new index to characterize the scientific output of researchers based on the h- and g-indices
TL;DR: This paper presents a new index, called hg-index, to characterize the scientific output of researchers which is based on both h-index and g-index to try to keep the advantages of both measures as well as to minimize their disadvantages.

Detecting the historical roots of research fields by reference publication year spectroscopy RPYS
TL;DR: Reference Publication Year Spectroscopy (RPYS) as discussed by the authors is a method based on the analysis of the frequency with which references are cited in the publications of a specific research field in terms of the cited references.

On generalising scientometric journal mapping beyond ISI's journal and citation databases
TL;DR: Results of this study indicate that a journal content-based map was not only far superior to the journal citation map, but also outperformed the map derived from the combination of both types of data.
