OCR systems struggle with traditional Mongolian script's vertical, cursive nature

Traditional Mongolian script, known as Mongol bichig, presents unique challenges for standard Optical Character Recognition (OCR) systems. These systems typically assume text runs horizontally, failing to process the vertical, top-to-bottom columns of Mongolian script. Even when rotated to make columns appear as rows, the cursive nature of the script and context-dependent letter forms, where multiple characters share identical medial shapes, mean that visual information alone is insufficient for accurate recognition. Determining the correct character often relies on linguistic context, such as vowel harmony and word meaning, rather than solely on the ink patterns present in the image. AI
