If you are in the business of language translation or require a proofreading service for your business or academic pursuits, then one service that can come in useful to you is a linguistic validation service. A linguistics validation service, as a concept, can provide proofreaders for any document that requires validation, especially those that involve people who use languages that differ from their own, for example, native English speakers, or speakers of other languages, for example, Spanish or Chinese. It may also be useful for such tasks as checking documents for accuracy, checking to make sure that a document is grammatically correct and punctuated correctly. It can even check for word coherence within a document and sentence alignment.
Many language translations and validation services offer professional linguistic, cultural, and historical sources alongside their services. They can provide information on the cultural context of a particular language, as well as historical references to how certain words and phrases are used.
