Co‐citation analysis and the invisible college

Journal of the American Society for Information Science, 1984
AbstractCo‐citation analysis is based on the assumption that all citing articles view the scientific literature from a common point‐of‐view. When a co‐citation matrix is analyzed, this assumption affects measures of the dimensionality and clustering of articles.

Critical thresholds in co‐citation graphs

Journal of the American Society for Information Science, 1985
AbstractUsing the Random Graph Hypothesis, the statistical validity of co‐citation graphs has been investigated as a function of co‐citation strength for a given value of citation frequency. The results show that for both high and low values of co‐citation strength the partition of cited documents produced by the co‐citation relationship may be ...

Analysis of citation and co-citation in chemical engineering

Scientometrics, 1993
This paper presents the results of the citation study in 24 leading journals on chemical engineering for 1987. The selective methodology or the analysis of co-citation limited only to this discipline is based on relatively low thresholds of citation and co-citation. The established research fronts refer mostly to basic research. The flow of information

Enhanced co-citation analysis using frameworks

Technology Analysis & Strategic Management, 2008
Abstract The valuation of intangible assets, such as patents, has recently been considered an important technique for R&D strategies. This paper proposes a citation analysis as a method of valuation on patent clusters having patent networks. A citation analysis is a method that examines the value of a patent on the basis of the number of citations of ...

CO-CITATIONS AND RELEVANCE OF AUTHORS AND AUTHOR GROUPS

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2011
The way an author or a group of authors are cited tells more about the real impact of their work than authorship and collaborations. Indeed, the connections within the scientific community can be more accurately elicited from the co-citation graph than from the collaboration graph.

Journal co-citation analysis of semiconductor literature

Scientometrics, 2003
The purpose of this study is to map semiconductor literature using journal co-citation analysis. The journal sample was gathered from the INSPEC database from 1978 to 1997. In the co-citation analysis, the data compiled were counts of the number of times two journal titles were jointly cited in later publications.

Author co-citation analysis of semiconductor literature

Scientometrics, 2003
The purpose of this study is to map semiconductor literature by author co-citation analysis in order to highlight major subject specializations in semiconductors and identify authors and their relationships within these specialties and within the field. Forty-six of the most productive authors were included in the sample list.

Co-citations and co-sitations: A cautionary view on an analogy

Scientometrics, 2002
Like the citation network of scientific publications, the Web is also a graph where pages are connected together by hypertext links or “sitations”. In the new research field Webometrics, scholars have investigated equivalencies between citationist concepts established in bibliometrics and hyperlinks networks.

Evaluations of context-based co-citation searching

Scientometrics, 2012
Since machine-readable documents have become widespread, some recent studies have proposed retrieval methods using a combination of citation linkage and its context. In the case of co-citation linkage, there have been attempts to discern `strong' co-citations from `weak' ones by examining the positions of citations in a document.

A Co-Citation Study of AIDS Research

Communication Research, 1989
A co-citation analysis of research on acquired immune deficiency syndrome is presented, covering the years 1982 to 1987. Through the use of cluster strings and co-citation maps at various levels of aggregation, the development of the field is traced, including major findings and shifts in research emphasis.
