Building ontological knowledge bases for sharing knowledge in digital archive

This study describes a framework of building ontological knowledge bases to restrengthen current digital archive systems. The approaches promote the service level from information to knowledge that further provides somatic capability for systems. The development technologies for building an ontological knowledge base include as follows: the formal concept analysis (FCA) can be used as a concepts extraction, the ontology Web language (OWL) present knowledge, and description logic is used to define axioms of knowledge. Empirical lessons indicate that ontological techniques provide potential approaches for content holders to share and reuse knowledge with their communities.
