UDDI and WSDL do not provide sufficient grounds to find appropriate Web services at the required accuracy and quality of service (QoS) level by the consumer. This article discusses a semantic search agent (SSA) approach that discovers appropriate Web services according to semantic description. The descriptions comprise QoS requirements and input/output information of fetched Web services according to consumer requirements. This study considers a broker or dispatcher model which consists of a QoS broker-based scheme by a multi-class queuing model. We depicted a new system that is an extension of the SSA to find appropriate Web services according to consumer request based on matching of input/output and QoS information of Web services; then compose them according to consumer requirements through semantic Web and ontology.
