1. Set usage permissions

Set the usage permissions of CLOVA OCR. Usage permissions of CLOVA OCR are defined by mapping role" to sub accounts issued by NAVER Cloud Platform's Sub Account. Therefore, you need to first create sub accounts other than your main account through Sub Account.

2. Create domain

Create a domain to begin producing your CLOVA OCR service. A domain is a unit that becomes the basis for operation and management of features provided by CLOVA OCR, such as template creation, channel linkage, and statistical information search. The domain creation method differs slightly by service type. You can refer to the following guides:

• Domains whose service type is General: OCR that extracts text/tables

• Domains whose service type is Template: OCR that supports template builder, which can directly specify analysis areas, extract recognized values, test them, and then send results
  • Creation and management methods: Template
• Domains whose service type is Document: OCR equipped with a specialized model engine that understands document's semantic structure based on machine learning, and automatically extracts key values
  • Creation and management methods: Document

3. Set OCR by service type

Once you've created a domain for each service type, you need to set up each service type to use the actual OCR feature. You can refer to the following guides:

• Domains whose service type is General: General
• Domains whose service type is Template: Template
• Domains whose service type is Document: Document

4. Linkage settings
