Multimodal sentiment analysis based on multiple attention

Abstract

The development of the Internet makes various types of data widely appear on various social platforms, multimodal data provides a new perspective for sentiment analysis. Although the data types are different, there are information expressing the same sentiment. The existing researches on extracting those information are static, and this means that there is a problem of extracting common information in a fixed amount. Therefore, to address this problem, we proposes a method named multimodal sentiment analysis based on multiple attention(MAMSA). Firstly, this method utilized the adaptive attention interaction module to dynamically determine the amount of information contributed by text and image features in multimodal fusion, and multimodal common representations are extracted through cross modal attention to improve the performance of each modal feature representation. Secondly, using sentiment information as a guide to extract text and image features related to sentiment. Finally, using hierarchical manner to fully learning the internal correlations between sentiment-text association representation, sentiment-image association representation, and multimodal common information to improve the performance of the model. We conducted extensive experiments using two public multimodal datasets, and the experimental results validated the availability of the proposed method.
