Creating ontological metadata for digital library content and services

We create ontological content metadata by generating it from MARC (MAchine Readable Cataloging) data. MARC contains much information that is hard to exploit computationally. In particular, relationships between works are implicit in shared values and natural language notes. The conversion process involves specifying an ontological model, mapping MARC to the ontology, and reasoning about the data to create explicit links between works.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/42334/1/799-2-1-20_80020020.pd
