KorAP web service client package for R

CRAN_Status_Badge CRAN downloads Project Status: Active – The project has reached a stable, usable state and is being actively developed. Lifecycle:stable Codecov test coverage Last commit GitHub closed issues GitHub issues check-windows check-mac check-linux Github Stars

Description

R client package to access the web service API of the KorAP Corpus Analysis Platform developed at IDS Mannheim

Examples

Hello world

library(RKorAPClient)
new("KorAPConnection", verbose=TRUE) %>% corpusQuery("Hello world") %>% fetchAll()

Frequencies over time and domains using ggplot2

library(RKorAPClient)
library(ggplot2)
kco <- new("KorAPConnection", verbose=TRUE)
expand_grid(condition = c("textDomain = /Wirtschaft.*/", "textDomain != /Wirtschaft.*/"), 
            year = (2002:2018)) %>%
    cbind(frequencyQuery(kco, "[tt/l=Heuschrecke]", paste0(.$condition," & pubDate in ", .$year)))  %>%
    ipm() %>%
    ggplot(aes(x = year, y = ipm, fill = condition, colour = condition)) +
    geom_freq_by_year_ci()

Percentages over time using highcharter

See the Highcharts license notes below.

library(RKorAPClient)
query = c("macht []{0,3} Sinn", "ergibt []{0,3} Sinn")
years = c(1980:2010)
as.alternatives = TRUE
vc = "textType = /Zeit.*/ & pubDate in"
new("KorAPConnection", verbose=T) %>%
  frequencyQuery(query, paste(vc, years), as.alternatives = as.alternatives) %>%
  hc_freq_by_year_ci(as.alternatives)

Proportion of "ergibt … Sinn" versus "macht … Sinn" between 1980 and 2010 in newspapers and magazines

Identify in … setzen light verb constructions by using the new collocationAnalysis function

Lifecycle:experimental

library(RKorAPClient)
library(knitr)
new("KorAPConnection", verbose = TRUE) %>%
  collocationAnalysis(
    "focus(in [tt/p=NN] {[tt/l=setzen]})",
    leftContextSize = 1,
    rightContextSize = 0,
    exactFrequencies = FALSE,
    searchHitsSampleLimit = 1000,
    topCollocatesLimit = 20
  ) %>%
  mutate(LVC = sprintf("[in %s setzen](%s)", collocate, webUIRequestUrl)) %>%
  select(LVC, logDice, pmi, ll) %>%
  head(10) %>%

Demos

More elaborate R scripts demonstrating the use of the package can be found in the demo folder.

Installation

Install R and RStudio

On Windows or Mac

  1. Install latest R version (>= 3.6) from CRAN
  2. Install latest RStudio from RStudio server

On Linux

On Linux you can choose, whether to install R and RStudio from your linux distribution's package maintainer or, like described above, for Windows and Mac. However, in any case, you first need to install some system dependencies required by R packages used by RKorAPClient:

# Debian / Ubuntu
sudo apt install r-base-dev libcurl4-gnutls-dev libxml2-dev libsodium-dev libsecret-1-dev libfontconfig1-dev libssl-dev

# Fedora / CentOS / RHEL (for older versions use `yum` instead of `dnf`)
sudo dnf install R-devel libcurl-devel openssl-devel libxml2-devel libsodium-devel libsecret-devel fontconfig-devel

# Arch Linux
pacman -S base-devel gcc-fortran libsodium curl

Install the RKorAPClient package

In RStudio

Start RStudio and click on Install Packages… in the Tools menu. Enter RKorAPClient in the Packages input field and click on the Install button (keeping Install Dependencies checked).

Installation of RKorAPClient package in RStudio

Or from the command line

Start R, then install RKorAPClient from CRAN (or development version from GitHub or KorAP's gerrit server).

CRAN version:
install.packages("RKorAPClient")
Development version (alternatives):
devtools::install_github("KorAP/RKorAPClient")
remotes::install_github("KorAP/RKorAPClient")
devtools::install_git("https://korap.ids-mannheim.de/gerrit/KorAP/RKorAPClient")
remotes::install_git("https://korap.ids-mannheim.de/gerrit/KorAP/RKorAPClient")
