QWN-PPV is a method to automatically generate polarity lexicons. It only requires a Lexical Knowledge Base (LKB) such as Wordnet and a list of positive and negative seeds (either words or synsets). The algorithm propagates the initial polarities through the LKB projected over a graph by means of the UKB Personalized PageRank algorithm.

Resulting lexicons are polarity annotated at synset and lemma level.
