The blog texts in the Swedish Diachronic Corpus are derived from
Språkbanken's collection 'Bloggmix', containing Swedish blog texts
from the time period 1998--2017, selected based on statistics on the
most visited private and professional blogs, as well as the most
visited blogs in different Swedish regions.
