Document Intelligence contract model

Important

• Document Intelligence public preview releases provide early access to features that are in active development. Features, approaches, and processes may change, prior to General Availability (GA), based on user feedback.
• The public preview version of Document Intelligence client libraries default to REST API version 2024-07-31-preview.
• Public preview version 2024-07-31-preview is currently only available in the following Azure regions. Note that the custom generative (document field extraction) model in AI Foundry portal is only available in North Central US region:
  • East US
  • West US2
  • West Europe
  • North Central US

This content applies to: v4.0 (preview) | Previous version: v3.1 (GA)

The Document Intelligence contract model uses powerful Optical Character Recognition (OCR) capabilities to analyze and extract key fields and line items from a select group of important contract entities. Contracts can be of various formats and quality including phone-captured images, scanned documents, and digital PDFs. The API analyzes document text; extracts key information such as Parties, Jurisdictions, Contract ID, and Title; and returns a structured JSON data representation. The model currently supports English-language document formats.

Automated contract processing

Automated contract processing is the process of extracting key contract fields from documents. Historically, the contract analysis process is achieved manually and, hence, very time consuming. Accurate extraction of key data from contracts is typically the first and one of the most critical steps in the contract automation process.

Development options

Document Intelligence v4.0 (2024-07-31-preview) supports the following tools, applications, and libraries:

• For best results, provide one clear photo or high-quality scan per document.

• For PDF and TIFF, up to 2,000 pages can be processed (with a free tier subscription, only the first two pages are processed).

• The file size for analyzing documents is 500 MB for paid (S0) tier and 4 MB for free (F0) tier.

• Image dimensions must be between 50 pixels x 50 pixels and 10,000 pixels x 10,000 pixels.

• If your PDFs are password-locked, you must remove the lock before submission.

• The minimum height of the text to be extracted is 12 pixels for a 1024 x 768 pixel image. This dimension corresponds to about 8 point text at 150 dots per inch (DPI).

• For custom model training, the maximum number of pages for training data is 500 for the custom template model and 50,000 for the custom neural model.

  • For custom extraction model training, the total size of training data is 50 MB for template model and 1 GB for the neural model.

  • For custom classification model training, the total size of training data is 1 GB with a maximum of 10,000 pages. For 2024-07-31-preview and later, the total size of training data is 2 GB with a maximum of 10,000 pages.

Try contract document data extraction

See how data, including customer information, vendor details, and line items, is extracted from contracts. You need the following resources:

• An Azure subscription—you can create one for free.

• A Document Intelligence instance in the Azure portal. You can use the free pricing tier (F0) to try the service. After your resource deploys, select Go to resource to get your key and endpoint.

Document Intelligence Studio

1. On the Document Intelligence Studio home page, select Tax Documents.

2. You can analyze the sample tax documents or upload your own files.

3. Select the Run analysis button and, if necessary, configure the Analyze options:

Field extraction

• For supported document extraction fields, refer to the contract model schema page in our GitHub sample repository.

• The contract key-value pairs and line items extracted are in the documentResults section of the JSON output.

Next steps

• Try processing your own forms and documents with the Document Intelligence Studio.

• Complete a Document Intelligence quickstart and get started creating a document processing app in the development language of your choice.
