A Semantic Matchmaking System Mechanism for Web Service Discovery Based on OWL-S
Hengtai Ma · Dianzi xuebao · 2010
The paper proposes an OWL-S based semantic web service matchmaking system mechanism,which imports semantic elements into UDDI,and preserves semantic information in UDDI storage.The system employs a semantic service matchmaking algorithm to improve precision and recall of service matching,and uses a data mapping mechanism to ensure the compatibility with present web service discovery standards,UDDI,and the transparency of UDDI APIs.The paper designs an ontology concept indexing mechanism for the system to improve the efficiency of service discovery.Moreover,in the processes of building and maintaining the indices,or alternatively,matching services,the system uses a similar concept searching algorithm to further enhance the efficiency of ontology concept searching and service matchmaking.
