The article highlights significant limitations encountered in evaluating NLP systems intended for identifying emotional support in clinical notes. A notable challenge was the lack of sufficient instances in the emotional support subcategories, which hindered a comprehensive evaluation. The research indicated that while a lexicon-based approach was used, it likely resulted in overfitting and inflated performance measurements. The authors suggest that more diverse clinical data and a systematic validation across various electronic health record (EHR) systems are essential for improving these NLP methodologies.
Emotional support subcategories were underrepresented, limiting the evaluation of NLP systems designed to identify such nuances in clinical notes, highlighting important gaps in clinical data.
The RBS's reliance on a limited lexicon may have resulted in overfitting and inflated performance metrics, necessitating validation across different electronic health records.
