Meta-Field Tag Extraction
It extracts other field tags, different from the standard WoS/SCOPUS codify.
metaTagExtraction(M, Field = "CR_AU", sep = ";", aff.disamb = TRUE)
M |
is a data frame obtained by the converting function |
||||||||||||||||||
Field |
is a character object. New tag extracted from aggregated data is specified by this string. Field can be equal to one of these tags:
|
||||||||||||||||||
sep |

(univ, research centers, etc.). The default is |
the bibliometric data frame with a new column containing data about new field tag indicated in the argument Field.
convert2df for importing and converting bibliographic files into a data frame.
biblioAnalysis function for bibliometric analysis
# Example 1: First Authors for each cited reference data(scientometrics, package = "bibliometrixData") scientometrics <- metaTagExtraction(scientometrics, Field = "CR_AU", sep = ";") unlist(strsplit(scientometrics$CR_AU[1], ";")) #Example 2: Source for each cited reference data(scientometrics) scientometrics <- metaTagExtraction(scientometrics, Field = "CR_SO", sep = ";") unlist(strsplit(scientometrics$CR_SO[1], ";")) #Example 3: Affiliation country for co-authors data(scientometrics) scientometrics <- metaTagExtraction(scientometrics, Field = "AU_CO", sep = ";") scientometrics$AU_CO[1:10]
