MEDICAL ENTITY EXTRACTION FROM PATIENT DATA

摘要

Members of a medical entity class are extracted (24) from patient data. A semi-supervised approach uses one or more initial medical terms (22), such as terms from an ontology, for a given category or medical canonical entity. A larger set of medical terms is extracted (24) from the medical information. In one example, the extraction is performed using lexical surface form features (26), rather than syntactical parsing
