To overcome this challenge, we developed two contrasting methods to generate large quantities of parallel data for GEC: Unlike several other machine translation tasks (such as translating from English to French), there is very little parallel data for GEC. To train high quality models, we generally want to have millions or billions of examples of parallel data, where each training example consists of a sentence in the source language paired with its translation in the target language. Since Grammatical Error Correction (GEC) can be viewed as "translation" from ungrammatical to grammatical sentences, sequence-to-sequence models developed for neural machine translation can be applied to this task. With the latest advancements from our research team in the area of language understanding-made possible by neural machine translation-soon, we’re making a significant improvement to how we correct language errors by using Neural Grammar Correction in Docs.

Essentially each suggestion is treated like a translation task-in this case, translating from the language of 'incorrect grammar' to the language of 'correct grammar.' At a basic level, machine translation performs substitution and reorders words from a source language to a target language, for example, substituting a “source” word in English (“hello”) for a “target” word in Spanish (“hola”). To date, Google’s grammar correction system uses machine translation technology. With the help of machine learning, already more than 100 million grammar suggestions are flagged each week.Īdvancing grammar suggestions using neural machine translation We’re focused on providing more assistive writing capabilities in G Suite to help you put your best work forward, which is why earlier this year we introduced new grammar correction tools in Google Docs to help people write more quickly and accurately. Spelling or grammatical errors can be distracting and make a proposal look unprofessional-something we all want to avoid. First impressions are everything in the workplace, and these often take place in the documents or presentations that we share with others.
