RethinkingTMSC: An Empirical Study for Target-Oriented Multimodal Sentiment Classification

Anonymous

Abstract: Recently, Target-oriented Multimodal Sentiment Classification (TMSC) has gained significant attention among scholars. However, current multimodal models have reached a performance bottleneck. To investigate the causes of this problem, we perform extensive empirical evaluation and in-depth analysis of the datasets to answer the following questions: \textbf{Q1}: Are the modalities equally important for TMSC? \textbf{Q2}: Which multimodal fusion modules are more effective? \textbf{Q3}: Do existing datasets adequately support the research? Our experiments and analysis reveal that the current TMSC systems primarily rely on the textual modality as most of targets' sentiments can be determined \emph{solely} by text. Furthermore, many images even lack targets in existing datasets. Therefore, constructing a more suitable dataset for TMSC is urgently needed since it has seriously hindered the research progress.
