The quality of electronic data at hospital information systems (HIS) varies between highly structured data (typically found at radiology information systems (RIS), laboratory information systems (LIS) or electronic health records (EHR)) and poorly structured data. Beside that, for historical reasons, there still exists many paper-based or otherwise non-digital sources that are not yet electronically developed.
While making structured data sources available is (well ... comparatively) easy, poorly or unstructured data needs the assistance of NLP functionalites.
