Answer overview
The next diagram reveals a totally serverless structure that makes use of Amazon Bedrock Knowledge Automation together with AWS Step Features and Amazon Augmented AI (Amazon A2I) to offer cost-effective scaling for doc processing workloads of various sizes.
The Step Features workflow processes a number of doc varieties together with multipage PDFs and pictures utilizing Amazon Bedrock Knowledge Automation. It makes use of varied Amazon Bedrock Knowledge Automation blueprints (each customary and customized) inside a single mission to allow processing of numerous doc varieties corresponding to immunization paperwork, conveyance tax certificates, baby assist providers enrollment types, and driver licenses.
The workflow processes a file (PDF, JPG, PNG, TIFF, DOC, DOCX) containing a single doc or a number of paperwork by the next steps:
- For multi-page paperwork, splits alongside logical doc boundaries
- Matches every doc to the suitable blueprint
- Applies the blueprint’s particular extraction directions to retrieve data from every doc
- Carry out normalization, Transformation and validation on extracted information based on the instruction laid out in blueprint
The Step Features Map state is used to course of every doc. If a doc meets the boldness threshold, the output is shipped to an Amazon Easy Storage Service (Amazon S3) bucket. If any extracted information falls under the boldness threshold, the doc is shipped to Amazon A2I for human assessment. Reviewers use the Amazon A2I UI with bounding field highlighting for chosen fields to confirm the extraction outcomes. When the human assessment is full, the callback activity token is used to renew the state machine and human-reviewed output is shipped to an S3 bucket.
To deploy this resolution in an AWS account, observe the steps offered within the accompanying GitHub repository.
Within the following sections, we assessment the particular Amazon Bedrock Knowledge Automation options deployed utilizing this resolution, utilizing the instance of a kid assist enrollment kind.
Automated Classification
In our implementation, we outline the doc class identify for every customized blueprint created, as illustrated within the following screenshot. When processing a number of doc varieties, corresponding to driver’s licenses and baby assist enrollment types, the system routinely applies the suitable blueprint based mostly on content material evaluation, ensuring the proper extraction logic is used for every doc sort.
Knowledge Normalization
We use information normalization to verify downstream techniques obtain uniformly formatted information. We use each express extractions (for clearly said data seen within the doc) and implicit extractions (for data that wants transformation). For instance, as proven within the following screenshot, dates of beginning are standardized to YYYY-MM-DD format.
Equally, format of Social Safety Numbers is modified to XXX-XX-XXXX.
Knowledge Transformation
For the kid assist enrollment utility, we’ve applied customized information transformations to align extracted information with particular necessities. One instance is our customized information sort for addresses, which breaks down single-line addresses into structured fields (Road, Metropolis, State, ZipCode). These structured fields are reused throughout completely different deal with fields within the enrollment kind (employer deal with, house deal with, different father or mother deal with), leading to constant formatting and simple integration with current techniques.
Knowledge Validation
Our implementation contains validation guidelines for sustaining information accuracy and compliance. For our instance use case, we’ve applied two validations: 1. confirm the presence of the enrollee’s signature and a pair of. confirm that the signed date isn’t sooner or later.
