What are the main features of OCI Document Understanding?

The main features of OCI Document Understanding include text extraction, table extraction, key-value extraction, and document classification.

How does OCI Document Understanding extract text from documents?

OCI Document Understanding uses pre-built AI models to extract text from documents. It identifies and processes the text based on tokens generated from the document content.

What types of documents can OCI Document Understanding handle?

OCI Document Understanding can handle various types of documents such as invoices, receipts, handwritten letters, and other forms of structured or semi-structured documents.

What is the process for extracting tables using OCI Document Understanding?

To extract tables, users can upload a document containing a table to OCI Document Understanding. The service will then extract and display the table data, making it available in a structured format.

What is the difference between text extraction and table extraction in OCI Document Understanding?

Text extraction focuses on extracting raw text from the document, while table extraction specifically targets tables within the document, preserving the structure and content of rows and columns.

How does OCI Document Understanding extract key-value pairs from documents?

OCI Document Understanding extracts key-value pairs by identifying specific pieces of information, such as addresses or invoice IDs, from the document. These pairs are extracted based on predefined data types.

What types of documents can OCI Document Understanding classify?

OCI Document Understanding can classify documents into various categories such as invoices, pay slips, checks, resumes, receipts, passports, and more.

How does the document classification feature work in OCI Document Understanding?

OCI Document Understanding classifies documents by analyzing the content and structure of the document, comparing it to pre-trained models to determine the correct category (e.g., invoice, receipt).
