Co-Citation Analyses of Science: An Evaluation

Social Studies of Science, 1977
For the past several years, Henry Small and collaborators1 have been arguing strongly on behalf of the utility of a technique called 'co-citation analysis' as a tool for understanding the specialty structure of science. Data which we have collected over the past two years on a specialty in elementary particle physics, the study of weak interactions,2 ...

Towards all-author co-citation analysis

Information Processing & Management, 2006
The present study examines one of the fundamental aspects of author co-citation analysis (ACA): the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting: on the one hand, the ...

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.

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.

Mapping Modern Science Using Co-citation Analysis

2007 11th International Conference Information Visualization (IV '07), 2007
Bibliometric analysis is used as a measuring activity technique for basic research. There are many country level analyses of trends in scientific publications. These analyses give us an understanding of the macro-scale character of scientific activities. However, it is difficult to capture the qualitative evolution of scientific activities through them.

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.

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.

Deciphering Arabidopsis thaliana gene neighborhoods through bibliographic co-citations

Computers & Chemistry, 2002
In the framework of genome annotation, scientific literature is obviously the major source of biological knowledge. The aim of the work described in this paper is to exploit this source of data for the model plant Arabidopsis thaliana. The first step has consisted in constituting a relevant bibliographic references dataset for plant genomic research ...

Extracting spam blogs with co-citation clusters

Proceedings of the 17th international conference on World Wide Web, 2008
This paper reports the estimated number of spam blogs in order to assess their current state in the blogosphere. To extract spam blogs, I developed a traversal method among co-citation clusters of blogs from a spam seed. Spam seeds were collected in terms of high out-degree and spam keyword.
