From: Improving ascertainment of suicidal ideation and suicide attempt with natural language processing
Comparative analysis for extracting the top K highest ranked suicidal ideation (SI) and suicide attempt (SA) patients using various configurations of the suicide label assignment method described in Fig. 1. For each configuration, the label assignment method was run 1000 times. The “Patient retrieval: all” experiments include all the patients retrieved by the NLP system while the “Patient retrieval: w/ 1+ positive” experiments use only patients with at least one positive suicide mention in their notes. The “NLP” and “NLP + ICD” experiments were associated with methods using the label assignment probabilities \(p_{rank}\) and \(p_{NLP + ICD}\), respectively.
