A sentiment lexicon is a dictionary that assigns each term a polarity score representing the strength of the positive or negative affect associated with the term. We have devised a new method for estimating polarity scores from preference judgements of test persons. Here we provide both the source code for computing the polarity scores and an initial set of 200 German words with their polarities. Moreover, we provide a GUi for extending this lexicon with arbitrary words.
Available releases (see the file README for usage instructions):
- sentire-data-2.0.tgz: 199 words sentiment lexicon with all-pair comparisons and R-scripts for computing the scores (version 2.0 from 2017/10/26)
- wordrating-2.0.tgz: GUI for adding arbitrary words with R-script for computing the new scores.
