AWS Textract
AWS Textract is a fully managed machine learning service that automatically extracts text and data from scanned documents, including forms and tables. It enables users to digitize and analyze documents at scale, making it easier to process and understand large volumes of unstructured data.
Key Features
- Text Extraction: Extracts printed text and handwriting from scanned documents with high accuracy.
- Form Data Extraction: Recognizes and extracts key-value pairs from forms and tables within documents.
- Table Extraction: Identifies and extracts data from tables in documents, preserving the structure and relationships between cells.
- Searchable Text: Converts documents into searchable text, making it easier to find and manage information.
- Integration with AWS Services: Easily integrates with other AWS services such as S3 for storage and Lambda for automated workflows.
Architecture Overview
The following diagram illustrates how AWS Textract processes documents and extracts information:
- Document Input: Upload documents to AWS S3 or send directly via API for processing.
- Text Extraction: Textract uses machine learning models to analyze and extract text and data from documents.
- Data Processing: Extracted data is processed and formatted, with results including text, forms, and tables.
- Output and Integration: Results are returned via API and can be integrated into applications or stored in S3.
Use Cases
- Document Digitization: Convert physical documents into digital formats for easier storage, search, and management.
- Form Processing: Automate data entry and processing for forms, applications, and surveys.
- Invoice Management: Extract and analyze data from invoices for accounting and financial operations.
