Researchers have developed DECO-MWE, a new linguistic resource for analyzing sentiment in Korean text, specifically focusing on multiword expressions (MWEs). This resource utilizes the Local Grammar Graph (LGG) methodology, formalizing MWEs as a Finite-State Transducer. The DECO-MWE lexicon categorizes MWEs into four types, including standard polarity, domain-dependent polarity, named entity, and feature MWEs, achieving an f-measure of 0.806 in test corpora. The methodology and lexicon are intended for broad application in feature-based sentiment analysis. AI
