000008371 520__ $$aConfrontation naming tasks such as the Philadelphia Naming Test (PNT) are essential tools for the assessment and treatment of people with aphasia. One challenge to clinical use of the PNT is the complexity of its scoring guidelines. We build on work towards automatic classification of paraphasias by (1) demonstrating that machine learning models substantially improve performance on the paraphasia classification task, (2) providing insight into the behavior of the highest-performing model, and (3) reporting results on experiments with contextual semantic and item-level information. Our best model improves 8.1 F1 points over a manually-constructed decision tree classifier. For development of the semantic features, we used crowdsourcing methods to construct a dataset of linguistic contexts from the visually presented items on the PNT assessment.
