Open Source Libraries

Voikko is a spell checking, grammar checking, morphological analysis and hyphenation system. Spell checkers are available for multiple languages, other features for Finnish only.

A collection of open source libraries and tools that provide solutions for common problems in processing Arabic text, especially in web applications. text normalization, phrase segmentation, text indexing, stop word lists, common spelling mistakes.

Light library for easy translation of Java programs using annotations and reflection.

The Java Galician Locale is an implementation of Java localization SPIs which will allow the Java VM to use the Galician Language (locales "gl" and "gl_ES"), one of the official languages of Spain, which is not included in Sun's JVM distribution

i18n4java is an I18N framework for Java to change the way how strings are internationalized. This framework is inspired by QT's I18N framework and uses all features of Java's L10N to get a tiny and clean framework which helps to write clean code.

Note: development has been moved over to github! Please see https://github.com/iLib-js/iLib "I18N" means way more than just translation. Other libraries claim to be an i18n solution when translation and string formatting is really all they offer. Yes, iLib has classes that do translation too, but there is also much, much more. From date formatting to name parsing to phone number handling to collation, iLib has classes that do it. And, it has the ability to support thousands of possible locales. Everything in iLib is written in pure JS with minimal platform dependencies, so it works the same way in many different environments and browsers, from Chrome to Opera to node to Qt/QML. Over 17K unit tests help to guarantee this. ILib is also the library of choice for enyo apps on webOS which ships on over 10 million LG SmartTVs in over 135 countries. Give it a try and see if it can work for your app too!

Set of STL-compatible ICU-based facets for localization and internationalization of C++ programs.

The libRSF is an open source C++ library that provides several components that are required to estimate the state of a (robotic) system based on probabilistic methods. By applying the factor graph concept, well known from Graph SLAM, libRSF provides a robust solution for many sensor fusion problems. The general idea of factor graphs is to describe the state estimation problem as a graph of nodes (the state variables) that are connected by factors (measurements). The resulting graph optimization problem can be solved by applying non-linear least squares optimization.

Modern javascript i18n localization library based on ES6 tagged templates and the good old GNU gettext. Just tag your strings to make them translatable. Use a simple ttag-cli tool for translation extraction. Can be easily integrated with almost any workflow as it uses the babel-plugin for string extraction. Can be easily used with the typescript. Allows you to place translations into the sources on a build step. Gettext is a simple localization format with a rich ecosystem. Ttag has support for plurals, contexts, translator comments, and much more.
