Text corpus

The Dhatki corpus used in this project consists of original sentences written by the researcher. Unlike other collections that rely on religious texts or folk stories, this corpus is self-constructed (Rishi Parkash) to represent natural and everyday usage of Dhatki.

The corpus contains 2,055 sentences: 2,055 validated and 0 unvalidated (0 pending review, 0 rejected), with 0 reported for review.

Writing system

The corpus is written in the Sindhi script. While Dhatki can be written in either Perso-Arabic (Sindhi-based) or Devanagari, this dataset follows the Sindhi convention, reflecting the variety spoken in Pakistan (Sindh).
