orWaC: Oromo corpus from the web
The Oromo web corpus (orWaC) is an Oromo corpus made up of texts collected from the Internet. The corpus was prepared according to standards described in the document A Corpus Factory for Many Languages (Kilgarriff et al. at LREC 2010).
Data was crawled by the SpiderLing web spider in January 2016 and comprised of 4 million words.
