Query Relaxing Based on Ontology and Users_ Behavior in Service Discovery
Lian Li, Jun Ma, Jingsheng Lei, Ling Song, Dongmei Zhang · 2007
Relaxing a failing query to the successful one with smallest semantic gap is the goal in Web service discovery. A schema for query relaxing is proposed based on both service ontologies and users' behavior, where the conceptual hierarchies and the conceptual distribution density of the ontologies are taken into account during query relaxing and the conceptual hierarchies of a ontology are enlarged based on users' behavior. A failing query can be relaxed to a successful one based on service ontologies and users' behavior with progressive processing.
