Intellectual structure

Author co-citation

Co-citation analysis is the most commonly used bibliometric analysis method (Ding, Chowdhury, and Foo 2001), and is defined as two publications that are cited together in one article (Small 1973).

# extract author names from reference items
df <- metaTagExtraction(df,
                        Field = "CR_AU")

# author co-citation network
auth.co.mat <- biblioNetwork(df,

Author coupling

Coupling is a similarity measure that uses citation analysis to illustrate a similarity relationship between documents. Author coupling occurs when two authors reference a common third author in their bibliographies.

# author coupling network
auth.coup.mat <- biblioNetwork(df, 
                             analysis = "coupling", 
                             network = "authors", 
                             sep = ";")

# network plot
auth.coup.net = networkPlot(auth.coup.mat, 
                          n = 50,

                          edgesize = 5, 
                          edges.min = 8,

Conceptual structure

Co-word analysis

The co-word analysis maps the conceptual structure of a research domain using the co-occurrence of author keywords in the bibliographic collection.

Authors’ keywords

# using authors keywords
cw <- conceptualStructure(df, 
                          field = "DE", 
                          method = "MDS", 
                          minDegree = 2, 
                          clust = "auto", 
                          stemming = FALSE, 
                          labelsize = 10, 
                          documents = 50)

Thematic mapping

From (Cobo et al. 2011, 150–51):

  • Themes in the upper-right quadrant are both well developed and important for the structuring ofa research field. They are known as the motor-themes of the specialty, given that they present strong centrality and high density. The placement of themesin this quadrantimplies that theyare related externally to concepts applicable to otherthemesthat are conceptually closely related.
  • Themes in the upper-left quadrant have well developed internal ties but unimportant external ties and so are of only marginal importance for the field. These themes are very specialized and peripheral in character.
  • Themes in the lower-left quadrant are both weakly developed and marginal. The themes ofthis quadrant have low density and low centrality, mainly representing either emerging or disappearing themes.
  • Themes in the lower-right quadrant are important for a research field but are not developed. So, this quadrant groups transversal and general, basic themes.
