A Reproducible Journal Classification and Global Map of Science Based on Aggregated Journal-Journal Citation Relations

  title={A Reproducible Journal Classification and Global Map of Science Based on Aggregated Journal-Journal Citation Relations},
  author={Loet Leydesdorff and Lutz Bornmann and Ping Zhou},
A number of journal classification systems have been developed in bibliometrics since the launch of the Citation Indices by the Institute of Scientific Information (ISI) in the 1960s. The best known system is the so-called "Web-of-Science Subject Categories" (WCs). Each system has its own advantages and disadvantages. Using the Journal Citation Reports 2014 of the Science Citation Index and the Social Science Citation Index (n of journals = 11,149), we examine the options for developing an… 
Visualization and analysis of SCImago Journal & Country Rank structure via journal clustering
This is the first study using Persson’s combination of most popular citation-based links (direct citation, co-citation and bibliographic coupling) in order to develop a scientogram based on Scopus journals from SJR.


Content-based and algorithmic classifications of journals: Perspectives on the dynamics of scientific communication and indexer effects
This study test the results of two recently available algorithms for the decomposition of large matrices against two content-based classifications of journals: the ISI Subject Categories and the field-subfield classification of Glanzel and Schubert (2003).
Definition and identification of journals as bibliographic and subject entities: Librarianship versus ISI Journal Citation Reports methods and their effect on citation measures
This paper explores the ISI Journal Citation Reports (JCR) bibliographic and subject structures through Library of Congress (LC) and American research libraries cataloging and classification
The structure of the Arts & Humanities Citation Index: A mapping on the basis of aggregated citations among 1,157 journals
Using the Arts & Humanities Citation Index (A&HCI) 2008, mapping techniques previously developed for mapping journal structures in the Science and Social Sciences Citation Indices are applied and a division into approximately 12 subsets is suggested.
Clustering of scientific journals
A cluster analysis procedure is described in which 288 journals in the disciplines of physics, chemistry and molecular biology are grouped into clusters and two‐step citation maps linking the clusters are presented for each discipline.
Caveats for the Use of Citation Indicators in Research and Journal Evaluations
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.

Relativity of citation performance and excellence measures: From cross-field to cross-scale effects of field-normalisation
The results show that the average citation rankings of articles substantially change with the level of observation, and the instability of impact measures should not be interpreted in terms of lack of robustness but rather as the co-existence of various perspectives each having their own form of legitimacy.
Which Type of Citation Analysis Generates the Most Accurate Taxonomy of Scientific and Technical Knowledge?
Direct citation provides a more accurate representation of the taxonomy of scientific and technical knowledge than either bibliographic coupling or co‐citation, and it is found that discipline‐level taxonomies based on journal schema are highly inaccurate compared to topic‐levelTaxonomies, and recommend against their use.
