Langram - the most accurate language detection library

308 ScriptLanguages (187 models + 121 single language scripts)

One language can be written in multiple scripts, so it will be detected as a different ScriptLanguage (language + script)

Uses alphabet_detector as a word separator + language prefilter.

Based on char (not word) n-gram language model modified algorithm.

This library is a complete rewrite of Lingua: 5x faster, more accuracy, more languages, etc.

Setup

To use it, you need to patch langram_models in Cargo.toml:

• From Git:

[patch.crates-io]
langram_models = { git = "https://github.com/RoDmitry/langram_models.git" }

• From predownloaded copy:

[patch.crates-io]
langram_models = { path = "../langram_models" }

Which is more advanced and allows you to remove model ngrams, so that final executable would be lighter.
