KSORD( Key Search over Relational Database) is currently an important research direction,it unions the efficient storing of structured data in traditional databases and the user-friendly and efficient unstructured data query in information retrieval systems. This paper introduces the design and implementation of a semantics based KSORD system. The system,which can utilize the semantics of ontology to do key search over relational database,is based on the enterprise development standard: J2 EE,with the integration of database,semantic Web and keyword search technologies. The main implementation technology issues: reverted index,concept similarity,semantic scoring formula are further analyzed. A revised inverted index structure and a new semantics based information retrieval scoring formula are proposed.
