Welcome to European Language Grid Documentation

The European Language Grid (ELG) is a platform dedicated to Language Technology (LT). It is developed in the framework of the ELG project and aims to evolve into the primary platform and virtual market place for all products, services and organizations active in the LT space in Europe. The platform can be used by all stakeholders to showcase, share and distribute their products, services, tools and data resources.
