Development of an Ontology-Based Portal for Digital Archive Services

In this paper we report employing ontology technology to develop a web portal for the digital archive service. The portal is divided into information provision and information access parts Each part works with an ontology, the knowledge structures commonly used in the digital library environment. The portal plays the role of an information aggregator that collects and unifies the information from different digital libraries and provides users with seamless service interface to access the content in an integrated way.
