Prerequisites
Before you begin, ensure you have the following:
- An AWS account with appropriate permissions.
- An S3 bucket containing newspaper images.
- An IAM role with permissions for Amazon Textract, S3, and AWS Lambda (optional for automation).
- The AWS CLI or SDK (Boto3 for Python) installed.
Step 1: Upload Newspaper Images to S3
Navigate to the AWS S3 Console.
Create or select an existing bucket.
Upload the newspaper images you want to process.
Step 2: Create an IAM Role for Textract
Go to the AWS IAM Console.
Create a new role with the following permissions:
{
"Effect": "Allow",
"Action": [
"textract:StartDocumentTextDetection",
"textract:GetDocumentTextDetection",
"s3:GetObject",
"s3:PutObject"
],
"Resource": "*"
}
Step 3: Start a Textract Batch Processing Job
Using the AWS CLI, start the text extraction job:
aws textract start-document-text-detection \
--document-location "S3Object={Bucket=,Name=}" \
--notification-channel "RoleArn=,SNSTopicArn="
Step 4: Retrieve the Extracted Text
Once the job is completed, retrieve the results:
aws textract get-document-text-detection --job-id
Step 5: Store and Process Extracted Text
Once you extract the text, you can:
- Store it in an S3 bucket.
- Process it with AWS Lambda and DynamoDB.
- Perform text analysis using Amazon Comprehend.
Conclusion
Using Amazon Textract, you can efficiently extract text from newspaper images stored in S3 via batch processing. This enables large-scale document processing, automation, and text analytics in AWS.
