Decreased Speech Coherence Captured by Novel Natural Language Processing Methods in Two Cohorts of Individuals With Schizophrenia

Computerized natural language processing (NLP) allows for objective and sensitive detection of decreased speech coherence, long considered a hallmark of schizophrenia spectrum disorders (SSD). We applied a state-of-the-art language model incorporating bidirectional context in word embedding to assess coherence and explored lexical differences between SSD and healthy comparison (HC)...
