Sub-ontology mapping based web services discovery framework

摘要

In order to improve the efficiency of semantic web service discovery and overcome the ontology heterogeneity problem in distributed environment. This paper proposed a sub-ontology mapping based framework for the discovery of web services, and then presented a discovery algorithm that supports the service discovery across the ontologies. In this framework, sub-ontology extraction module was introduced to reduce the ontology mapping scale. The sub-ontology was extracted from the reference ontology through the extraction concept set of service functional description information. The experimental results confirm the viability and efficiency of the discovery system.
