C-C1-02: Data Extraction From Text, Step 1: Preparing Test for Machine Processing

By David Carrell


Background: Natural language processing (NLP) uses software to assist in the extraction of information from clinical text, a process usually performed entirely by chart abstractors. Before NLP can be applied the text in question must be prepared for machine processing. In research settings this pre- processing work often involves several successive and related tasks, requiring substantial amounts of time and attention from people representing various types of clinical, scientific and technical expertise. Appreciating the tasks and participants involved in pre-processing clinical text can make the work more manageable, efficient, and effective
