The corpus contains all the discussion forums of the Suomi24 online social networking website from 1st January 2001 to 31st December 2017 available in the Suomi24 API. Researchers can download the entire corpus (see http://urn.fi/urn:nbn:fi:lb-2020021801). Updates: 2021-04-21: In the updated version 1.2, some new annotations were inserted. Each sentence in the corpus now includes sentiment annotation (polarity: positive, negative, or neutral). The polarity information was obtained with an automatic classifier, trained with the FinnSentiment data (http://urn.fi/urn:nbn:fi:lb-2020111001; see also Lindén, Jauhiainen & Hardwick, 2020). 2020-02-20: The updated version 1.1 includes some minor corrections: in the previous version, the nicknames of writers were missing in some posts from the years 2009–2012 and 2014, and the characters ', " and & that occurred in some nicknames were incorrectly displayed as ', " or &. Moreover, the part "2017H2" in the previous title of the corpus was replaced by the years "2001–2017".
