The AFINN_SENTIMENT data set in the SAMPSIO library is new in this release. It is adapted from the AFINN sentiment publically available English sentiment lexicon. It contains two topics, ‘Positive Tone’ and ‘Negative Tone’, that can be used as User Topics in the Text Topic node. The AFINN_SENTIMENT data set contains information from the AFINN sentiment database, which is made available under the Open Database License.
