Details
Kakaopay Insurance introduced Document AI to reduce the document review time that occurs during insurance claims. This automated the process that was previously reviewed manually by people, reducing customer wait time to under 10 minutes.
Document AI is a technology that automatically finds desired information in document images and extracts it in Key-Value form. The main component Tasks are as follows.
- OCR: Recognizes characters in the document and detects their location (Bounding Box)
- Layout Analysis: Analyzes the structure of the document, such as titles, tables, and body text
- Classification: Classifies the type of document to support logic branching
- Parsing: Converts recognized text into data that fits service requirements
For actual repair cost receipt recognition, a 4-step process is applied: Edge Detection, Layout Analysis, OCR, and Parsing. Edge Detection performs preprocessing to correct tilted images, and Layout Analysis identifies specific information areas.
Finally, text is extracted with OCR, and in the Parsing step, structured data such as "amount": 80,000 is generated using regular expressions, among other methods.
