  abstract =     "We developed linguistics-driven prediction models to
                 estimate the risk of suicide. These models were
                 generated from unstructured clinical notes taken from a
                 national sample of U.S. Veterans Administration (VA)
                 medical records. We created three matched cohorts:
                 veterans who committed suicide, veterans who used
                 mental health services and did not commit suicide, and
                 veterans who did not use mental health services and did
                 not commit suicide during the observation period (n =
                 70 in each group). From the clinical notes, we
                 generated datasets of single keywords and multi-word
                 phrases, and constructed prediction models using a
                 machine-learning algorithm based on a genetic
                 programming framework. The resulting inference accuracy
                 was consistently 65percent or more. Our data therefore
                 suggests that computerised text analytics can be
                 applied to unstructured medical records to estimate the
                 risk of suicide. The resulting system could allow
                 clinicians to potentially screen seemingly healthy
                 patients at the primary care level, and to continuously
                 evaluate the suicide risk among psychiatric patients.",
