Discourse modes play an important role in writing composition and evaluation.This paper presents a study on the manual and automatic identification of narration, exposition, description, argument and emotion expressing sentences in narrative essays.We annotate a corpus to study the characteristics of discourse modes and describe a neural sequence labeling model for identification.Evaluation results show that discourse modes can be identified automatically with an average F1-score of 0.7.We further demonstrate that discourse modes can be used as features that improve automatic essay scoring (AES).The impacts of discourse modes for AES are also discussed.
