Automatic metadata conversion system with ontology

Abstract

Some information providers or information circulation centers are collecting various metadata to serve users. The collected information has various structures and expression types of contents as well as file types. For information service, these various types of metadata should be processed and converted into one unified form. Converting metadata has lots of difficulties and mapping between elements of metadata schema is most important and difficult. We are making an automatic metadata conversion system with ontology. This paper describes the conversion method with ontology and schema mapping tool in the system. © 2011 Springer-Verlag.
