Current literature applying natural language processing (NLP) methods, (including large language models (LLMs)), to extract psychopathological information from the EHR is briefly reviewed. Schizophrenia is then used as a case study for an in-depth critical examination of the assumptions and complexities inherent in mapping MSE findings to their corresponding psychopathological constructs. Principles for subject-matter-expert review of MSE data are proposed alongside a sample conceptual organization of MSE findings according to the main psychopathological domains of schizophrenia. Contributions made by MSE data at the research frontier are discussed, and the limitations of MSE data are considered.<\/jats:p>\n
