Mapping Australian geophysics: A co-heading analysis

Abstract

Descriptive capacities of a new bibliometric method, namely co-heading analysis, are investigated. The method uses the appearance and co-appearance of classification subdivisions ~ (headings) in the document records of 1988 INSPEC database to display correspondingly the main topics of Australian geophysics and their links. The findings, in the form of inclusion maps (resulting from multidimensional scaling and cluster analysis) provide new insights into geophysics national activity and into its structure.

Bibliometric Methods: Pitfalls and Possibilities

“…Text mining offers a variety of approaches for extracting information and knowledge from textual data (Leopold et al 2004). Co‐heading analysis has been developed by Todorov & Winterhager (1990) and Todorov (1992), and is based on the co‐occurrence of subject headings. This approach shows some advantage as compared to other bibliometric coupling methods.…”

Contrasting views of software engineering journals: Author cocitation choices and indexer vocabulary assignments

“…Examination of classification terms, such as headings or descriptors, is an established method for structural analysis of a knowledge domain (Coulter et al, 1996;Engelsman & van Raan, 1994;Healey, Rothman, & Hoch, 1986;Hinze, 1994;McCain, 1995aMcCain, , 1995bTodorov & Winterhager, 1990). The assignment of indexing terms represents the subject analyst's view of the subject content rather than the author's view, as expressed in word and citation choice.…”

Assessment of journal similarity based on citing discipline analysis

“…The use of subject categories as a basis for the comparison of bibliographic entities or disciplinary areas can also be found in the research literature. Todorov and Winterhager () applied coheading analysis of records in the Inspec database and multidimensional scaling to provide insights into the structure of Australian geophysics research. Tijssen () used a similar approach that he referred to as “coclassification analysis” based on the co‐occurrence of different subject classification headings assigned to publications to reveal the interdisciplinary structure of energy research and the strength of interdisciplinary relationships.…”
