Abstract

This research integrates Discourse Simplification (DisSim) into aspect-based sentiment analysis (ABSA) to improve aspect selection and sentiment prediction in complex financial texts, particularly central bank communications. The study focuses on decomposing Federal Open Market Committee (FOMC) minutes into simple, canonical structures to identify key sentences encapsulating the core messages of intricate financial narratives. The investigation examines whether hierarchical segmenting of financial texts can enhance ABSA performance using a pre-trained Financial BERT model. Results indicate that DisSim methods enhance aspect selection accuracy in simplified texts compared to untreated counterparts and show empirical improvement in sentiment prediction. The study concludes that decomposing complex financial texts into shorter segments with Discourse Simplification can lead to more precise aspect selection, thereby facilitating more accurate economic analyses.
