          Papago Translation is a NAVER Cloud Platform service that automatically translates languages from multiple countries (sources) to target languages through Neural Machine Translation (NMT) algorithm based on artificial neural networks. It provides APIs for text translation, document translation, web translation, language detection, and glossary features in RESTful form, and you need to complete IAM authentication with API Gateway to call the APIs.
