Here, the enrichment step consists of tagging words based on sentiment, i.e. positive or negative, according to a list of positive and negative words.
The node for this task is the Dictionary Tagger node.
The list of positive words and negative words belonging to MPQA is available at: http://mpqa.cs.pitt.edu/corpora/mpqa_corpus/
A wildcard Tagger node is also used at the end to associate a few words with a named entity (NE) tag with value ORGANIZATIONS.
