Discourse Classification into Rhetorical Functions for AWE Feedback

Abstract: This paper reports on the development of the analysis engine for the Research Writing Tutor (RWT), an AWE program designed to provide genre and discipline-specific feedback on the functional units of research article discourse. Unlike traditional NLP-based applications that categorize complete documents, RWT's analyzer categorizes every sentence in the text as both a communicative move and a rhetorical step. We describe the construction of a cascade of two support vector machine classifiers trained on a multi-… Show more

“…Automated Assessment of Writing -Existing, academic writing tools have focused on identifying author intentions, such as those described by Swales (1990), that can be found in an Introduction (Cotos and Pendar, 2016;Anthony and V. Lashkia, 2003;Abel, 2018). The Criterion online writing service, focuses on automated persuasive essay evaluation and uses recognition of discourse elements based on aspects such as supporting ideas, introductions and conclusion (Burstein et al, 2003(Burstein et al, , 2004.…”

“…Unlike traditional AWE systems, RWT's feedback draws students' attention to the rhetorical conventions of a research genre, as opposed to grammatical correctness and elements of style in essays. The backbone of this module is an analysis engine that is trained to classify every sentence of a student text into moves and respective steps (for details see Cotos & Pendar, 2016). The results of classification are translated to different types of macro and micro-level feedback generated when students submit their drafts for automated analysis.…”

“…The automated analysis performed by RWT's engine also anticipates a scale-up. While it yields acceptable move/step classification measures (Cotos & Pendar, 2016), feedback accuracy remains to be improved. Also, the system classifies sentences only into one move and one step, but often sentences in published texts represent more than one rhetorical function.…”

“…Using the annotated corpus data and the statistical properties of n-grams in our corpus, probabilistic language models for predicting the occurrence of moves and steps were built to generate rhetorical feedback (Babu, 2013;Cotos, Gilbert, & Sinapov, 2014). RWT's analysis engine approaches the identification of these discourse units as a supervised classification problem (see Burstein, Marcu, & Knight, 2003;Pendar & Cotos, 2008), where each sentence in a text is considered an independent unit of analysis to be classified into two categories -one corresponding to a move and the second corresponding to a step within the identified move.…”
