CORRECT: Document recognition service

Updated June 14, 2024

The CORRECT service allows you to extract information from documents of various types and contents. The service determines the type and structure of the document, recognizes text and barcode values, finds the tabular part, and checks for the presence of seals, stamps and signatures. One template allows you to process many different types of documents of the same type.

The service performs image preparation (alignment, rotation, focusing, changing resolution) and
checking extracted data such as:

  • mathematical checks of line-by-line, total, checksums, VAT;
  • checks according to the Unified State Register of Legal Entities, Unified State Register of Individual Entrepreneurs, directories of names, addresses, codes and names of departments, nomenclatures.

The document recognition result is a document structure with fields. For each field, the Service returns confidence in the recognized data, pointers to uncertainly recognized characters, and field coordinates on the page image.

The necessary templates are connected by the administrator in the service web interface. The use of templates is included in the price and is not paid for.
