In 2015 we set the bar to 500 thousand tokens, mostly because of our results on morphosyntactic annotation of Slovene (Ljubešić and Erjavec, 2016) which showed corpus supervision to be of much greater importance than lexicon supervision.
the second phase of corpus construction consisted of manually selecting 320k tokens of suitable documents from the hrWaC web corpus and having experts do correction of automated morphosyntactic annotation learned from the 190k-sized corpus.
