Document Intelligence marriage certificate model

  • Article

This content applies to: checkmark v4.0 (preview) checkmark

The Document Intelligence Marriage Certificate model uses powerful Optical Character Recognition (OCR) capabilities to analyze and extract key fields from Marriage Certificates. Marriage certificates 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 Spouse names, Issue date, and marriage place; and returns a structured JSON data representation. The model currently supports English-language document formats.

Automated marriage certificate processing

Automated marriage certificate processing is the process of extracting key fields from Marriage certificates. Historically, the marriage certificate analysis process is achieved manually and, hence, very time consuming. Accurate extraction of key data from marriage certificates is typically the first and one of the most critical steps in the marriage certificate 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 marriage certificate document data extraction

To see how data extraction works for the marriage certificate card service, 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 Marriage Certificate.

  2. You can analyze the sample Marriage certificates or upload your own files.

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