BhashaSutra: A Task-Centric Unified Survey of Indian NLP Datasets, Corpora, and Resources
Researchers released BhashaSutra, the first comprehensive survey of Indian NLP resources, cataloging 200+ datasets, 50+ benchmarks, and 100+ models across 22 scheduled languages. The work addresses a gap in low-resource and culturally diverse language coverage, organizing resources by linguistic phenomena, domains, and modalities including speech and multimodal tasks.

ExplainerThe survey's real contribution isn't the count of datasets but the organizational framework: by grouping resources around linguistic phenomena and task types rather than just language names, BhashaSutra makes it easier for researchers to identify gaps rather than just inventory what exists. That gap-mapping function is what prior Indian NLP surveys have largely skipped.
The challenge of building capable models under data and resource constraints has been a recurring thread in recent coverage. The ESsEN paper from April 20 showed that architectural choices matter enormously when training data is scarce, a condition that describes virtually every Indian language outside Hindi. BhashaSutra is, in effect, the supply-side answer to that problem: before you can make smart architectural trade-offs for low-resource settings, you need a clear picture of what training material actually exists. The MADE benchmark from April 16 offers a parallel case in a different domain, where a living, well-organized benchmark accelerated model evaluation in a specialized field. The same logic applies here across 22 languages.
Watch whether any of the 50+ benchmarks cataloged here get adopted into a multilingual evaluation suite by a major lab within the next 12 months. Adoption by an external party would signal that BhashaSutra is functioning as infrastructure rather than a one-time literature review.
