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 2024-02-29-preview.
• Public preview version 2024-02-29-preview is currently only available in the following Azure regions:
• East US
• West US2
• West Europe

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 (2024-02-29-preview) supports the following tools, applications, and libraries:

Feature	Resources	Model ID
Contract model	• Document Intelligence Studio • REST API • C# SDK • Python SDK • Java SDK • JavaScript SDK	prebuilt-contract

Input requirements

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

• Supported file formats:

  Model	PDF	Image: JPEG/JPG, PNG, BMP, TIFF, HEIF	Microsoft Office: Word (DOCX), Excel (XLSX), PowerPoint (PPTX), and HTML
  Read	✔	✔	✔
  Layout	✔	✔	✔ (2024-02-29-preview, 2023-10-31-preview)
  General Document	✔	✔
  Prebuilt	✔	✔
  Custom extraction	✔	✔
  Custom classification	✔	✔	✔ (2024-02-29-preview)

• For PDF and TIFF, up to 2000 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 x 50 pixels and 10,000 px 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 1G-MB for the neural model.

  • For custom classification model training, the total size of training data is 1GB 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

The following are the fields extracted from a contract in the JSON output response.

Name	Type	Description	Example output
Title	String	Contract title	Service agreement
ContractId	String	Contract title	AB12956
Parties	Array	List of legal parties
ExecutionDate	Date	Date when the agreement was fully signed and agreed upon by all parties	On this twenty-third day of February two thousand and twenty two
ExpirationDate	Date	Date when the contract ends to be in effect	One year
RenewalDate	Date	Date when the contract needs to be renewed	On this twenty-third day of February two thousand and twenty two
Jurisdictions	Array	List of jurisdictions

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