Geo-ontology-aided semantic search of Web resources (Kamel Boulos, 2002). Metadata alone are not enough for successful retrieval of the Web resource/page shown in this figure. In this example, even though the resource and its metadata do not mention 'exposure risk to Borrelia Burgdorferi in north-eastern United States', a multiple ontology (geo-ontology and disease ontology)-assisted search for 'exposure risk to Borrelia Burgdorferi in north-eastern United States' would be able to find the resource [34].
