The article presents analysis of Polish Internet political discussion forums, characterized by significant polarization and high levels of emotion. The study compares samples of discussions gathered from the Internet comments concerning the last Polish election candidates. The authors compare three dictionary based sentiment analysis methods (built using different sentiment lexicons) with two machine learning ones, and explore methods using word embeddings to enhance sentiment analysis using dictionary based algorithms. The best performing algorithm is giving results closely corresponding to human evaluations.
