Slovene Sentiment Lexicon KSS

Version 1.1, 2017-04-14

The Slovene opinion lexicon is based on the manually translated opinion lexicon of Hu & Liu (2004).  The lexicon is updated with some positive and negative words typical for Slovenian language. There are three versions of the lexicon.
Each version of the lexicon contains two files, one for negative and one for positive words in a text format, one word per line. 'The lexicon also contains some multi-word units where the individual words are joined with an underscore, e.g. "bolezenska_znamenja".
