This paper presents work on the automatic creation of a polarity lexicon based on a lexical-semantic network. During this work, we noticed that the language registers of a relation should be considered in polarity propagation. After analysing the possible registers and performing some experiments, our intuition was confirmed – there are registers that should invert the transmitted polarity (irony), while others always transmit negative polarity (pejorative, disparaging).
