Abstract excerpt

OBJECTIVE: To develop algorithms to improve efficiency of patient phenotyping using natural language processing (NLP) on text data. Of a large number of note titles available in our database, we sought to determine those with highest yield and precision for psychosocial concepts. MATERIALS AND METHODS: From a database of over 1 billion documents from US Department of Veterans Affairs medical facilities, a random...
