metaTagExtraction: Meta-Field Tag Extraction

In xiangtuochen/bibliometrixfullname: Comprehensive Science Mapping Analysis

Description

It extracts other field tags, different from the standard WoS/SCOPUS codify.

Usage

metaTagExtraction(M, Field = "CR_AU", sep = ";", aff.disamb = TRUE)

Arguments

M	is a data frame obtained by the converting function convert2df. It is a data matrix with cases corresponding to articles and variables to Field Tag in the original WoS or SCOPUS file.
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: "CR_AU" First Author of each cited reference "CR_SO" Source of each cited reference "AU_CO" Country of affiliation for co-authors "AU1_CO" Country of affiliation for the first author "AU_UN" University of affiliation for each co-author and the corresponding author (AU1_UN) "SR" Short tag of the document (as used in reference lists)
sep	is the field separator character. This character separates strings in each column of the data frame. The default is sep = ";".
aff.disamb	is a logical. If TRUE and Field="AU_UN", then a disambiguation algorithm is used to identify and match scientific affiliations (univ, research centers, etc.). The default is aff.disamb=TRUE.

Value

the bibliometric data frame with a new column containing data about new field tag indicated in the argument Field.

Examples

# 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]
