To this end, we implement a computational model that leverages the protagonist's mental state information obtained from a pre-trained model trained on social commonsense knowledge and integrates their representations with contextual semantic embed-dings using a multi-feature fusion approach.

Second, we ask non-narrative experts to annotate those clauses under Labov's sociolinguistic model of personal narratives (i. e., action, orientation, and evaluation clause types) and train a classifier that reaches 84. 7% F-score for the highest-agreed clauses.
