Apertium is an open-source platform focused on rule-based machine translation, primarily aimed at translating between lesser-resourced and related language pairs. It offers tools and linguistic data for a variety of languages, with a strong emphasis on collaboration and community-driven development. The software framework used by Apertium is designed to be modular, making it easy to develop new language pairs and improve existing ones. Volunteers and developers can contribute to the project, helping it grow and expand its language offerings.
