“…Researchers have used machine learning methods to improve email efficiency by predicting email responses. Previous work includes predicting email importance and ranking by likelihood of user action (Aberdeen et al, 2010), classifying emails into common actions -read, reply, delete, and delete-WithoutRead (Di Castro et al, 2016), and characterizing response behavior based on various factors Kooti et al, 2015;Qadir et al, 2016) including time, length, and conversion, temporal, textual properties, and historical interactions. Our work differs from previous studies by considering both semantic and structural information in email response prediction and developing an interpretable model.…”
