Abstract
Systems and methods are disclosed for extracting structured relation information from Chinese clinical notes. Structured relation information in the form of entity-feature-value (EFV) triples is disclosed. The EFV triples may be used for advanced data abstraction. An ontology-driven method for data extraction is disclosed. The ontology-driven method may include lexical and syntactic analysis followed by semantic analysis to generate the EFV triples.
