Overview

About

Maintained by Meik MichalkeCRAN page ↗GitHub ↗Website ↗Issues ↗

A set of tools to analyze texts. Includes, amongst others, functions for automatic language detection, hyphenation, several indices of lexical diversity (e.g., type token ratio, HD-D/vocd-D, MTLD) and readability (e.g., Flesch, SMOG, LIX, Dale-Chall). Basic import functions for language corpora are also provided, to enable frequency analyses (supports Celex and Leipzig Corpora Collection file formats) and measures like tf-idf. Note: For full functionality a local installation of TreeTagger is recommended. It is also recommended to not load this package directly, but by loading one of the available language support packages from the 'l10n' repository https://undocumeantit.github.io/repos/l10n/. 'koRpus' also includes a plugin for the R GUI and IDE RKWard, providing graphical dialogs for its basic features. The respective R package 'rkward' cannot be installed directly from a repository, as it is a part of RKWard. To make full use of this feature, please install RKWard from https://rkward.kde.org (plugins are detected automatically). Due to some restrictions on CRAN, the full package sources are only available from the project homepage. To ask for help, report bugs, request features, or discuss the development of the package, please subscribe to the koRpus-dev mailing list (https://korpusml.reaktanz.de).

Changes in 0.13-9

fixed

lex.div(): if text was too short, calculation of MTLDMA.char would fail with an error; these cases now return NAs guess.lang(): newer zip files with UDHR translations introduced empty lines that caused problems freq.analysis(): internal function kRp.freq.analysis.calc() was trying to use an object called frequency.pre when it didn't exist kRp_text(): validity checks don't fail any more after adding corp_freq feature was added readability(): removed unused variant shortcut "Spache.de" dependencies: koRpus now requires sylly >= 0.1-7 because that fixed an issue with syllable count for texts where not a single word is shorter than three syllables: if the bug is triggered, SMOG() always returns -2. thanks to jana ludwig for reporting this! docs were fixed, mostly replacing "\itemize" with "\describe". thanks to gerry ryan for suggesting this!

changed

tokenize(): now fails with an error if text files/vectors are empty lex.div(): dropped all default measures from "char", it's rarely useful and should therefore be requested if really needed and not waste CPU otherwise lex.div()/readability()/query()/readTagged(): added match.arg() calls to improve verification of selected measures/indices/relations/tagger show() (kRp.lang): omit "region" if none is available, but added location code including a link to open street map dependencies: are recommended by the authors of the Matrix package, set requirements to Matrix (>= 1.3-0)

added

readability(): added all index shortcuts for varaints to the documentation vignette: new section explaining how to use readTagged() with third party POS taggers like the udpipe package

From inst/NEWS.Rd in the release

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("koRpus", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("unDocUMeantIt/koRpus")

Development version from unDocUMeantIt/koRpus. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-korpus

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-koRpus

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-koRpus

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
