Enriching Ontologies for Improved Access to Web Documents.
Thorsten Kurz, Kilian Stoffel · ICWI · 2002
The complex hierarchies of ontologies make it often difficult for human users to locate classes within them. We present in this paper a method to enrich classes of an existing light-weight ontology with additional keyword attributes that are learned from instances of these classes. Further we show a method to use these attributes for improving the recall of queries and for facilitating access to the classes in a result set after a query.
