Ontology-based semantic cache in AOKB
Zheng, H; Lu, RQ; Jin, Z; Hu, SK
AbstractWhen querying on a large-scale knowledge base, a major technique of improving performance is to preload knowledge to minimize the number of roundtrips to the knowledge base. In this paper, an ontology-based semantic cache is proposed for an agent and ontology-oriented knowledge base (AOKB). In AOKB, an ontology is the collection of relationships between a group of knowledge units (agents and/or other sub-ontologies). When loading some agent A, its relationships with other knowledge units are examined, and those who have a tight semantic tie with A will be preloaded at the same time, including agents and sub-ontologies in the same ontology where A is. The preloaded agents and ontologies are saved at a semantic cache located in the memory. Test results show that up to 50% reduction in running time is achieved.
