It extracts other field tags, different from the standard ISI/SCOPUS codify.
metaTagExtraction(M, Field = "CR_AU", sep = ";", aff.disamb = TRUE)
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 ISI or SCOPUS file.
is a character object. New tag exctracted from aggregated data is specified by this string. Field can be equal to one of this tags:
"CR_AU" |
First Author of each cited reference | |
"CR_SO" |
Source of each cited reference | |
"AU_CO" |
Country of affiliation for each co-author | |
"AU1_CO" |
Country of affiliation for the first author | |
"AU_UN" |
University of affiliation for each co-author and the corresponding author (AU1_UN) |
is the field separator character. This character separates strings in each column of the data frame. The default is sep = ";"
.
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
.
the bibliometric data frame with a new column containing data about new field tag indicated in the argument Field
