SJ/T 12111-2026Artificial intelligence - Technical requirements for intelligent character recognition (English PDF)

SJ/T 12111-2026 is the English-translated version of 人工智能 智能字符识别技术要求.

SJ/T 12111-2026 gives technical requirements for intelligent character recognition. Character recognition turns text found in images, scans or handwriting into machine-readable text, and the intelligent form uses artificial intelligence methods to do so. The document sets out what technical requirements apply to such recognition technology.

Software developers, makers of recognition products and scanning equipment, organisations that digitise documents, and test bodies can use it. The standard is voluntary, as the /T in its code shows. It was approved by the Ministry of Industry and Information Technology, issued on 28 April 2026 and takes effect on 28 April 2026. It is a new standard.

This preview omits tables, figures, formulas and parts of the technical clauses. The complete document — 21 pages — is available in the English PDF.
