Electronic word-of-mouth effects on studio performance leveraging attention-based model

Abstract

While existing studies have established the relationship between electronic word-of-mouth (eWOM) and studio performance, limited research has been conducted to demonstrate how the attention-based model applies to the motion pictureindustry. In this study, examining a review corpus of seven Hollywood studios, we proved that deep learning with theattention mechanism has the best accuracy in both eWOM and stock price movement. We present both a hierarchical two-layer attention network and hierarchical convoluted attention network (HCAN), which quantify the importance of crucialeWOM features in capturing valuable information from audience members’ reviews. Further, comparing the two casestudies, we determined that the HCAN model is superior to both machine learning and attention-based models. Our workhelps to highlight the business value of the attention-based model and has implications for studio business decisions.
