Write Spaces to Korean Sentences

Restores spacing in Korean sentences using a bundled neural network model and 'ONNX Runtime' < https://onnxruntime.ai/> through 'churon'. Inference runs locally without a web service or automatic downloads.

The goal of theeuh is to restore spacing in Korean sentences.

Installation

{theeuh} is not on CRAN. Install its CRAN dependency {churon}, then install {theeuh} from r-universe.

install.packages("churon")
install.packages(
  "theeuh",
  repos = c("https://mrchypark.r-universe.dev", "https://cloud.r-project.org")
)

{theeuh} uses {churon} for ONNX inference. On macOS arm64 and Linux x64/arm64, install ONNX Runtime in the current R session before first use:

churon::install_onnx_runtime(destdir = "~/.local/share/churon")
runtime_path <- Sys.getenv("ORT_DYLIB_PATH")
runtime_path

Save the printed path in ~/.Renviron for later R sessions, then restart R before loading {theeuh}:

ORT_DYLIB_PATH=/path/printed/above
ORT_DISABLE_TELEMETRY=1

ONNX Runtime supports macOS arm64, Linux x64/arm64, and Windows x64; macOS x86_64 is unsupported for ONNX Runtime 1.28.0 and later. The telemetry setting also covers sessions initialized by other packages.

Windows x64

The CRAN release of {churon} 0.1.13 cannot install ONNX Runtime on Windows: its installer calls utils::unzip(..., quiet = TRUE), but Windows base R does not accept that argument. Until {churon} fixes this, download the official ONNX Runtime 1.29.0 Windows x64 archive and install it with base R. Choose a persistent directory for destdir.

destdir <- "C:/Users/your-name/AppData/Local/churon"
dir.create(destdir, recursive = TRUE, showWarnings = FALSE)

zip_url <- paste0(
  "https://github.com/microsoft/onnxruntime/releases/download/v1.29.0/",
  "onnxruntime-win-x64-1.29.0.zip"
)
zip_file <- file.path(tempdir(), "onnxruntime-win-x64-1.29.0.zip")
utils::download.file(zip_url, zip_file, mode = "wb")
utils::unzip(zip_file, exdir = destdir)
unlink(zip_file)

runtime_path <- normalizePath(
  file.path(
    destdir, "onnxruntime-win-x64-1.29.0", "lib", "onnxruntime.dll"
  ),
  winslash = "/",
  mustWork = TRUE
)
Sys.setenv(ORT_DYLIB_PATH = runtime_path, ORT_DISABLE_TELEMETRY = "1")
runtime_path

For later R sessions, save the printed absolute path in ~/.Renviron, restart R, then load {theeuh}:

ORT_DYLIB_PATH=C:/Users/your-name/AppData/Local/churon/onnxruntime-win-x64-1.29.0/lib/onnxruntime.dll
ORT_DISABLE_TELEMETRY=1
