SentiWS
~~~~~~~

SentimentWortschatz, or SentiWS for short, is a publicly available German-language resource for sentiment analysis, opinion mining etc. It lists positive and negative polarity bearing words weighted within the interval of [-1; 1] plus their part of speech tag, and if applicable, their inflections. The current version of SentiWS (v1.8b) contains 1,650 positive and 1,818 negative words, which sum up to 15,649 positive and 15,632 negative word forms incl. their inflections, respectively. It not only contains adjectives and adverbs explicitly expressing a sentiment, but also nouns and verbs implicitly containing one.

Version History
~~~~~~~~~~~~~~~

SentiWS is "work in progress" and hence far from being fully-fledged and error-free. It will be continuously refined by adding missing words and word forms and removing ambiguous ones.

v1.8b, 2010-05-19: First publicly available version as described in Remus et al. (2010).
v1.8c, 2012-03-21: Second publicly available version in which some POS tags were corrected.
