Semantic Parsing for Aspect-Based Sentiment Analysis
Muhammad Aqeel, Francesco Setti · IEEE Access · 2025
This study introduces the Semantic Parsing Tree (SPT), a novel framework designed to enhance Aspect-Based Sentiment Analysis (ABSA). By integrating advanced attention mechanisms, our approach overcomes the limitations of traditional dependency trees, which often fail to capture the complex semantic relationships crucial for accurate sentiment prediction, particularly in intricate sentence constructs such as nested clauses or implicit sentiments. Converting syntactic trees into SPTs enables our model to preserve and analyze key semantic roles and relationships, facilitating precise sentiment analysis at the aspect level. The integration of SPT with an advanced graph-based attention mechanism, augmented by relational heads, enhances the deep encoding of semantic nuances, significantly improving sentiment analysis accuracy. Comprehensive evaluations across benchmark datasets, including SemEval 2014, Restaurant, and Twitter, indicate that this approach outperforms conventional models in both accuracy and adaptability.
