Machine Translation

Machine translation is the technology of automatically translating text written in one language into another language using AI or computers. While rule-based translation was once the dominant approach, neural machine translation (NMT) powered by deep learning is now widely used. This technology produces more natural translations that account for context, word order, phrasing, and semantic ambiguity — achieving translation quality approaching the level of human translators. Representative applications of machine translation: • Automatic translation of websites and apps (e.g., Google Translate, DeepL) • Translation support for global business documents and contracts • Real-time translation of multilingual emails and chat messages • Assistance with reading overseas news, academic papers, and technical documents • Multilingual customer support As a foundational technology enabling cross-border information sharing and business operations, machine translation has become indispensable — with particularly accelerating adoption in tourism, e-commerce, education, and international business.
