Solution Architecture and Implementation
The solution architecture of Azure Document Intelligence is a robust and efficient system that enables businesses to automate document processing. At its core, it consists of five key components: AI Builder, Form Recognizer, Power Automate, Azure Functions, and PnP Modern Search.
AI Builder is a Power Platform capability that lets you train models to recognize objects in images, while Form Recognizer uses machine-learning models to extract and analyze form fields, text, and tables from your documents. Power Automate is an online workflow service that automates actions across apps and services, and Azure Functions is an event-driven serverless compute platform that runs on demand and at scale in the cloud. PnP Modern Search is a set of SharePoint Online modern web parts that let you create highly flexible and personalized search-based experiences.
Here's a high-level overview of the solution architecture:
- AI Builder: Trains models for object recognition.
- Form Recognizer: Performs optical character recognition (OCR) on documents.
- Power Automate: Automates workflows based on document events.
- Azure Functions: Analyzes data and processes metadata.
- PnP Modern Search: Allows for custom document search experiences.
This architecture enables businesses to automate text extraction, improve searchability, and enhance document management by extracting and analyzing critical data from complex documents efficiently.

Best Practices
To ensure your custom model performs well, it's essential to follow some best practices. Start with a neural model and test its functionality to determine if it meets your needs.
Dealing with variations is a common challenge when working with custom models. Create a single model for all variations of a document type, and add at least five labeled samples for each variation to the training dataset.
Labeling fields properly is crucial for accurate key-value pairs extraction. Name fields in the language of the document, and make sure the field name is relevant to the value. For example, if a field contains a supplier ID, name it "supplier_id".
When labeling contiguous values, ensure that value tokens or words of one field are either separate or together. They can't be a mix of both.
Representative data in training cases is vital for model performance. Use diverse and representative values, such as actual dates, instead of synthetic values like random strings. This will help your model learn and generalize better.
Data Ingestion and Processing
Data Ingestion and Processing is a crucial step in Azure Document Intelligence.
Documents are ingested through a browser at the front end of a web application.
The back-end application posts a request to a Form Recognizer REST API endpoint that uses one of the models mentioned above.
The response from Form Recognizer contains raw OCR data and structured extractions.
The App Service back-end application uses the confidence values to check the extraction quality.
When the extraction quality meets requirements, the data enters Azure Cosmos DB for downstream application consumption.
