Adapted from: Akera, A. (2007) Constructing a representation for an ecology of knowledge: Methodological advances in the integration of knowledge and its various contexts. Social Studies of Science, 37(3), 413-441
Scientific documentsKey element in practice of science
(Callon, Courtial, Turner & Banin 1983; Latour & Woolgar 1986)
Shared conceptual system of scientific communities expressed through the terminology used in documents.
Disciplines/fields exist through a medium of ordered language.
Document titles
Function as “attention triggers” (Bazerman 1985,1989)
Have undergone a change during the 20th century, becoming
More informative
More specific
Containing a larger number of words that indicate article content
Leydesdorff (1989) : “title words seem to offer a means of making visible the internal cognitive structure” (p. 217) of a discipline.
Selecting terms for analysis
Identification of stop words and nonspecific words
Identification of unique words
Identification of phrases and construction of joint word/phrase list
Data analysis approaches
Relative word frequency analysis
Co-word analysis and hierarchical clustering
Multidimensional scaling analysis

Spatial correlation of time periods (individual years) based on the multidimensional scaling of 100 most frequently occurring article title terms in nanotechnology articles
Milojević, S..(in preparation), The formation and development of nanoscience/nanotechnology: Analysis of article title words
Heatmap of the term “scanning tunneling microscopy”. Diffusion of the term through nanotechnology subfields. PC3 = Physics and chemistry other (e.g. geochemistry & geophysics) => M5 = Materials science => MD2 = Medicine => B2 = Biophysics.
