The dynamic mapping of science using the data in theScience Citation Index was put on the research agenda of science studies byDe Solla Price in the mid 1960s. Recently, proponents of ‘co-citation cluster analysis’ have claimed that in principle their methodology makes such mapping possible. The study examines this claim, both methodologically and theoretically, in relation to other means of mapping science. A detailed study of a co-citation map, its core documents' citation patterns and the… 
The delineation of specialties in terms of journals using the dynamic journal set of the SCI
TLDR
The study discusses the various choices which have to be made, in both conceptual and methodological terms, and empirical reslts indicate the feasibility of dynamic journal-journal mapping by using these methods.
Reassessment of co-citation methods for science indicators: Effect of methods improving recall rates
TLDR
These investigations indicate that at the level of micro/meso studies high recall rates can be achieved by the use of appropriate clustering techniques limiting singletons and the enrichment of cocited cores by medium-cited items, providing that careful trade-offs are sought between the extension and relevance of recall.
Using co-authorship and citation analysis to identify research groups: a new way to assess performance
TLDR
The results show that the understanding of the scientific performance of an institution changes with a more careful account for the unit of analysis used in the assessment.
A global map of science based on the ISI subject categories
TLDR
The nested maps of science (corresponding to 14 factors, 172 categories, and 6,164 journals) are brought online and an analysis of interdisciplinary relations is pursued at three levels of aggregation using the newly added ISI subject category of "Nanoscience & nanotechnology".
A comparison of two bibliometric methods for mapping of the research front
TLDR
It was suggested that the research front was portrayed in two considerably different ways by the methods applied, and would support a further comparative study of these methods on a more detailed and qualitative ground.
Which Type of Citation Analysis Generates the Most Accurate Taxonomy of Scientific and Technical Knowledge?
TLDR
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.
Mapping the backbone of science
TLDR
A new map representing the structure of all of science, based on journal articles, is presented, including both the natural and social sciences, including biochemistry, which appears as the most interdisciplinary discipline in science.
Visualization of the citation impact environments of scientific journals: An online mapping exercise
TLDR
Aggregated journal–journal citation networks based on the Journal Citation Reports 2004 of the Science Citation Index and the Social science Citation Index are made accessible from the perspective of any of these journals.
Can scientific journals be classified in terms of aggregated journal-journal citation relations using the Journal Citation Reports?
TLDR
The factor-analytic solutions allow us to test classifications against the structures contained in the database; in this article the process will be demonstrated for the delineation of a set of biochemistry journals.
Top-down decomposition of the Journal Citation Reportof the Social Science Citation Index: Graph- and factor-analytical approaches
The aggregated journal-journal citation matrix of the Journal Citation Report 2001of the Social Science Citation Indexis analyzed as a single domain in terms of both its eigenvectors and the

Clustering the science citation index using co-citations. II. Mapping science
TLDR
The map shows a tightly integrated network of approximate disciplinary regions, unique in that for the first time links between mathematics and biomedical science have brought about a closure of the previously linear arrangement of disciplines.
Clustering of scientific journals
TLDR
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.
A technique of two-stage clustering applied to environmental and civil engineering and related methods of citation analysis
A method of two‐stage clustering of literature based on citation frequency is developed. This method enables one to cluster thousands of articles Into a simplified dendrogram by introducing a
Authors as markers of Intellectual Space: Co‐citation in studies of Science, Technology and Society
Interrelations of writings in a complex field such as studies of science, technology and society, turn out to be highly patterned when data on author co‐citations are statistically analysed and
The Structure of Scientific Literatures I: Identifying and Graphing Specialties
In this paper we report a first experiment using a new computer-based technique to identify clusters of highly interactive documents in science. We contend that these clusters represent the
Interrelationships of scientific journals
TLDR
A large amount of consistency was found between the citing characteristics of the journals in the different scientific fields, with quite clear boundaries between fields and a few well known cross disciplinary journals as cross field information links.
Advances in factor analysis and structural equation models
TLDR
The methods in this book do not provide final answers to the question of model specification but offer the researcher the flexibility to formulate and test a variety of causal models and to guide the analysis toward more adequate explanations of the relationships embedded in data.
Displaying strengths and weaknesses in national R&D performance through document cocitation
TLDR
Document cocitation analysis, as developed by Small and Griffith, was employed as a means of assessing current Dutch participation in science and the ideal distribution of scientific productivity for those countries was considered.
