⚡️ Features and Changes (April 25th, 2024)

  • 🚀  Extended latin alphabet support
    We released new models for our generic text detection and recognition pipeline. This release has increased the overall performances on all fields and supports extended latin alphabet characters:

    {'`', '¡', '¥', '¿', 'Á', 'Ã', 'Ä', 'Å', 'Æ', 'Ì', 'Í', 'Ð', 'Ñ', 'Ò', 'Ó', 'Õ', 'Ö', 'Ø', 'Ú', 'Ü', 'Ý', 'Þ', 'ß', 'á', 'ã', 'ä', 'å', 'æ', 'ì', 'í', 'ð', 'ñ', 'ò', 'ó', 'õ', 'ö', 'ø', 'ú', 'ü', 'ý', 'þ', 'Ā', 'ā', 'Ă', 'ă', 'Ą', 'ą', 'Ć', 'ć', 'Č', 'č', 'Ď', 'ď', 'Đ', 'đ', 'Ē', 'ē', 'Ė', 'ė', 'Ę', 'ę', 'Ě', 'ě', 'Ğ', 'ğ', 'Ģ', 'ģ', 'Ī', 'ī', 'Į', 'į', 'İ', 'ı', 'Ķ', 'ķ', 'Ĺ', 'ĺ', 'Ļ', 'ļ', 'Ľ', 'ľ', 'Ł', 'ł', 'Ń', 'ń', 'Ņ', 'ņ', 'Ň', 'ň', 'Ō', 'ō', 'Ő', 'ő', 'Ŕ', 'ŕ', 'Ŗ', 'ŗ', 'Ř', 'ř', 'Ś', 'ś', 'Ş', 'ş', 'Š', 'š', 'Ť', 'ť', 'Ū', 'ū', 'Ů', 'ů', 'Ű', 'ű', 'Ų', 'ų', 'Ź', 'ź', 'Ż', 'ż', 'Ž', 'ž', 'Ș', 'ș', 'Ț', 'ț', 'ẞ', '₿'}
    
  • 🔥 Strong improvement on due_date, line_items
    We have observed a reduction in error rates as follows:

    • 20% for due_date
    • 25% for line_items
  • ✨ New fields:
    The API is now extracting the following fields:
    customer_id: The identifier of the customer in the supplier’s referential. It can also refer to the client ID, client / customer account number…
    supplier_phone_number: The phone number of the supplier
    supplier_email: The supplier email address
    supplier_website: The supplier website URL

  • 🔥 General accuracy improvement
    Thanks to the improvement done on our generic text detection and recognition algorithms, we measured a reduction in error rates on all fields, especially for supplier and customer information.

⚡️ Features and Changes (March 11th, 2024)

  • 🚀  Integration of company ID & logo database
    We have integrated a company ID database and a vector database featuring millions of logos. This enhancement enables our R&D team to efficiently rectify any issues with non-functional supplier names.

  • 🔥 Strong improvement on supplier_name, customer_name, and invoice_number
    We have observed a reduction in error rates as follows:

    • 20% for customer_name
    • 15% for supplier_name
    • 10% for invoice_number

    The improvement in supplier_name was achieved by incorporating information from the databases. The customer_name algorithm now mirrors the supplier_name one. invoice_number now employs an NLP modality to boost its precision.

  • ✨ New fields: shipping_address, billing_address and tax_base:
    The API now extracts the shipping_address and billing_address.
    We have updated the taxes field to include the tax_base value. Including the tax_base value in the taxes field can help you calculate and report taxes more accurately.

⚡️ Features and Changes (January 30th, 2024)

  • 🚀 Integration of a proprietary language model in the algorithm pipeline: LiLT
    LILT: A Simple yet Effective Language-Independent Layout Transformer for Structured Document Understanding.
    LiLT's design combines textual content with layout structure. This means it doesn't just read the text but also understands how the text is organized within the document. For instance, it recognizes headings, paragraphs, tables, and other structural elements, which is a crucial aspect of context awareness in document processing.
    The integration of this new language model in our pipeline helps us achieve better accuracy, and more flexibility when adding new supported fields.
  • 🔥 Strong improvement on supplier_name, supplier_address, and supplier_company_registrations
    The main focus of this release was to improve drastically the supplier information extraction.
    We measured a decrease in error rates of:
    • 42% for supplier_name
    • 10% for supplier_address
    • 10% for supplier_company_registrations
      Moreover, the integration of the LILT offers more robustness in terms of languages thanks to its language-independent component and will help us improve all other fields in the next releases.
  • ✨ New field: total_tax
    The API is now extracting the total tax information, returned as a number. It corresponds to the total tax explicitly written in the document.
  • 🔥 General improvement for all fields
    More training data was added to our training set, including different geographies and more variability. We’ve measured an improvement in accuracy for all extracted fields.

⚡️ Features and Changes (September 1st, 2023)

  • ✨ New field: Raw Value available for both Supplier Name and Customer Name.
    The Raw Value extracts the name without post processing nor formatting. It can thus be different from the Value.

  • New field extracted: Reference numbers which is a list of variable size which may contain PO numbers, reference numbers or project numbers
