Applying Rhetorical Structure Theory to Student Essays for Providing Automated Writing Feedback


At NAACL-HLT 2019, I presented our work “Applying RST for Automated Structural Feedback for Student Essays” at DISRPT workshop.
[View the Paper] [Presentation Slides]


We present a package of annotation resources, including annotation guideline, flowchart, and an Intelligent Tutoring System for training human annotators. These resources can be used to apply Rhetorical Structure Theory (RST) to essays written by students in K-12 schools. Furthermore, we highlight the great potential of using RST to provide automated feedback for improving writing quality across genres.
