Language translation services translate documents, web sites, product information and personal communications into one more human languages. They may also provide authoring, editing, publishing, content management, and translation management services. Language translation services translate and interpret documents for multinational corporations, government agencies, schools and universities, and other organizations that require internationalization and localization. Internationalization is the process of designing a product such as a web site or software to work in multiple languages. Localization involves adapting the product to account for local or national language features. For example, language translation services that work with software companies may translate error messages into multiple languages for use within a single code base.
