1 논문 데이터
Dimensions 웹사이트에서 연구논문에 대한 서지목록을 가져온다. BibTeX은 \(\LaTeX\)와 같은 인쇄저작시스템과 결합하여 문서 서지관리를 위해 제작된 파일형식으로 다음과 같은 형태로 구성된다.
다음과 같이 도널드 쿠누쓰 교수의 1997년 책을 BibTeX 형식에 맞춰 파일에 저장시키고 나서 @knuth1997art 같이 컴퓨터 프로그래밍 예술[1]을 참조하면 저작물 작성에 유용하다.
\[1. Knuth DE. The art of computer programming. Pearson Education; 1997.\]
@book{knuth1997art,
title={The art of computer programming},
author={Knuth, Donald Ervin},
volume={3},
year={1997},
publisher={Pearson Education}
}2 BibTeX 데이터프레임
BibTeX 형태의 정보가 쌓이게 되면 이를 변환하여 데이터프레임으로 변환시킬 수 있다. 정형 데이터로부터 다양한 분석과 경우에 따라서는 예측모형 구축도 가능하게 된다.
bib2df 팩키지의 도움으로 BibTeX 파일을 데이터프레임으로 변환시킬 수 있다. bib2df에 기본으로 내장된 BibTeX 파일을 대상으로 작업을 수행해보자.
library(tidyverse)
library(bib2df)
bibtex_dat <- system.file("extdata", "LiteratureOnCommonKnowledgeInGameTheory.bib", package = "bib2df")
readr::read_lines(bibtex_dat) %>%
head(10) [1] "@Article{Arrow1986,"
[2] " Title = {Rationality of Self and Others in an Economic System},"
[3] " Author = {Arrow, Kenneth J.},"
[4] " Journal = {The Journal of Business},"
[5] " Year = {1986},"
[6] " Number = {4},"
[7] " Pages = {385--399},"
[8] " Volume = {59}"
[9] "}"
[10] "" bib2df() 함수를 통해 BibTeX 파일을 정형 데이터프레임으로 변환시킬 수 있다. 데이터프레임으로 변환이 되면 이후 다양한 분석작업을 수행할 수 있게 된다.
bibtex_tbl <- bib2df(bibtex_dat)
bibtex_tbl %>%
sample_n(10) %>%
janitor::clean_names() %>%
select(bibtexkey, author, title, year, journal) %>%
reactable::reactable()데이터프레임으로 변환이 되었기 때문에 dplyr와 ggplot을 결합시켜 탐색적 데이터분석 업무를 후속으로 이어 작업하면 좋다.
bibtex_tbl %>%
janitor::clean_names() %>%
select(year, author) %>%
unnest(cols = author) %>%
mutate(author = fct_reorder(author, year)) %>%
ggplot(aes(x = year, y = author)) +
geom_point() +
theme_light()
3 BibTeX 원자료 준비
https://www.dimensions.ai/ 웹사이트 가입하고 코로나19와 자연어처리 관련 논문을 추출하여 데이터를 준비해보자.
(Covid-19 OR CORONAVIRUS) AND (NLP OR Natural Language Processing)
다운로드 받은 데이터를 불러와서 본격적인 분석을 위한 준비를 한다.
covid_tbl <- bib2df("data/Dimensions-Publication-citations-2021-01-22_06-55-18.bib")
covid_tbl %>%
sample_n(10) %>%
janitor::clean_names() %>%
select(bibtexkey, author, title, year, journal) %>%
reactable::reactable()4 참고문헌 분석1
