The tool Data for Research (DfR) by JSTOR is a
valuable source for citation analysis and text mining. jstor
provides functions and suggests workflows for importing
datasets from DfR. It was developed to deal with very large datasets which
require an agreement, but can be used with smaller ones as well.
Note: As of 2021, JSTOR has moved changed the way they provide data to a new
platform called Constellate. The package jstor
has
not been adapted to this change, and might therefore only be used for legacy
data that was optained from the old DfR platform.
The most important set of functions is a group of jst_get_*
functions:
jst_get_article
jst_get_authors
jst_get_references
jst_get_footnotes
jst_get_book
jst_get_chapters
jst_get_full_text
jst_get_ngram
All functions which are concerned with meta data (therefore excluding
jst_get_full_text
and jst_get_ngram
) operate along the same lines:
xml2::read_xml()
.tibble
.To install the package use:
install.packages("jstor")
You can install the development version from GitHub with:
# install.packages("remotes") remotes::install_github("ropensci/jstor")
In order to use jstor
, you first need to load it:
library(jstor) library(magrittr)
The basic usage is simple: supply one of the jst_get_*
-functions with a path
and it will return a tibble with the extracted information.
jst_get_article(jst_example("article_with_references.xml")) %>% knitr::kable() jst_get_authors(jst_example("article_with_references.xml")) %>% knitr::kable()
Further explanations, especially on how to use jstor's functions for importing many files, can be found in the vignettes.
In order to use jstor
, you need some data from DfR. From the
main page you can create a dataset by searching for
terms and restricting the search regarding time, subject and content type. After
you created an account, you can download your selection. Alternatively,
you can download
sample datasets with documents
from before 1923 for the US, and before 1870 for all other countries.
In their technical specifications, DfR lists fields which should be reliably present in all articles and books.
The following table gives an overview, which elements are supported by jstor
.
