I. Introduction
A significant amount of patient information produced in hospitals is documented as free-text narratives (e.g., clinical notes/reports) by the caregivers. These clinical texts contain important insights and observations made by the caregiver about the patient’s health trajectory, and are arranged into different sections. For example, information about a patient’s past medical conditions can be found in the "Clinical History" section of the report, while the caregiver’s observations and interpretations are likely to appear in the "Findings" section, as shown in the sample report in Figure 1.
