Yuan An

Associate Professor

Information Science

Dr. An's research interests include health and biomedical information integration, extraction, and analysis; requirements analysis and engineering for healthcare information systems; semantic and ontology mapping; knowledge representation and reasoning. He has conducted research on discovering and using semantic mappings between different data representations including relational schemas, XML DTDs/schemas, ontologies, and other conceptual models. His current projects include helping healthcare providers gather and retrieve healthcare information in structured databases, indexing and searching biological Web interfaces, creating online schema repositories, and developing a case-based approach for schema design. His teaching interests include systems analysis and design, requirements engineering, software development, and database management systems.
