Veda OCR Dataset

Line images from printed editions of Vedic Saṃhitās, paired with transcriptions (ISO 15919, NFC). One config per text. There is no fixed train/test split, so choose your own; splitting by page avoids leakage between neighbouring lines.

Label conventions

• Printed section numbers are kept in the image and written as // n // in the label.
• Footnote markers may remain in the image but are not in the label.
• A word broken at the line end is marked with - in the label.
• Punctuation (/, //) follows the transcription, not always the print.

Known limitations

• Some images keep tiny specks of neighbouring-line strokes.
• Punctuation is not yet aligned to the print.

Sources

Transcriptions

The labels come from the electronic texts of the Maitrāyaṇī, Kāṭhaka and Taittirīya Saṃhitās prepared by Makoto Fushimi (Ōsaka). They were converted to ISO 15919, NFC-normalised, split into printed lines and corrected while building this dataset. Versions of these e-texts are also available from TITUS, for anyone who wants the continuous text.
