South African Centre for Digital Language Resources

What South African Centre for Digital Language Resources does

SADiLaR (South African Centre for Digital Language Resources) is a national research infrastructure hosted by North-West University and funded by the South African Department of Science, Technology and Innovation (DSTI) as part of the South African Research Infrastructure Roadmap (SARIR). Established in 2016 and officially launched on 7 August 2019 with an R81 million three-year grant, SADiLaR provides digital language resources and computational tools covering all 11 official languages of South Africa. Its primary users are university researchers, postgraduate students, and language practitioners; it operates a fully open-access model with no fees charged for any resources, tools, or training services.

The organisation's core product portfolio is anchored by the Language Resource Repository (406 assets as of August 2022, including text corpora, speech data, dictionaries, and translation memories), alongside Autshumato machine translation, the Corpus Portal, spelling checkers for ten languages, Voyant Tools for text analysis, ZulMorph for Zulu morphology, and Lwimilinks for resource linking. Technical capability is delivered through a six-node distributed model spanning North-West University (text/hub), University of Pretoria (digitisation), UNISA (African Wordnet), CSIR (speech/ASR/TTS), Stellenbosch University (child language), and ICELDA (language testing). SADiLaR's revenue is exclusively government grant funding; its go-to-market is community-led and event-driven, relying on DH-IGNITE regional roadshows, the ESCALATOR capacity-building programme, the SWiP Wikipedia/PanSALB partnership, and the Digital Champions Initiative to reach all 26 South African public universities.

SADiLaR's strategic position rests on its designation as the first non-European CLARIN ERIC member country (effective January 2024), making it the only African institutional member of this European language research infrastructure network. The organisation has no commercial revenue model and does not compete in commercial markets; its investment thesis centres on national-policy and public-good value rather than financial return.
