A new broker-based semantic Web service discovery framework for selecting and ranking suggested Web services

Nowadays, with the rapid development of Web services technologies as a solution to achieve SOA, the number of Web services on the web that offer similar functions is increasing. Therefore, not only the discovery and selection of the best Web services based on functional property requirements and preferences of users is not sufficient, but also owning to improve and achieve more accurate results, the non-functional properties (i.e. QoS) should be taken into consideration. In the existing paper, a new QoS-aware framework to improve the semantic Web service discovery based on broker by using ontology concepts has been proposed. Due to having real-time values of QoS attributes of web services, composite monitoring mechanism in which various WS-related applied reports continuously can be collected. These reports are compiled through WS monitoring agent, feedback from user, and provider advertisement.
