Document

Available in Classic and VPC

In the NAVER Cloud Platform console under CLOVA OCR > Domain, you can create and manage Document domains equipped with specialized machine learning–based model engines that understand the semantic structure of documents and automatically extract key-value information. Because Document OCR may include personal or sensitive information such as receipts, IDs, or business cards, it is available only after a prior application and approval process. Through the approval process, NAVER Cloud guides you on safe handling methods for personal and sensitive data (such as reference architecture).
This section describes how to create and use a domain of the Document service type. For instructions on viewing, deleting, and copying domains, as well as detailed steps for integrating with API Gateway, see Domain.
