A Dynamic Reputation-Based Approach for Web Services Discovery

Web services discovery is a crucial process in the\udservice-oriented architecture (SOA). This process depends on\udthe functional and non-functional (Quality of services (QoS))\udproperties of the published services. Functional properties\udpresent the objectives of the service and the quality of the\udservice indicates the performance of the service. Reputation of\udthe services is one of the important QoS properties. Assigning\udrobust and precise reputation values for the service affects\udpositively in the output of the web services discovery process by\udreturning the most relevant services for the consumer. In this\udpaper, we propose an approach for updating reputation of the\udWeb services based on the trust factors of the consumers and\udtwo pre-defined thresholds, reputation threshold, and agreement\udthreshold. The proposed approach is implemented and tested on\uda set of services. The results show that the proposed reputation\udupdating approach is powerful and gives robust and precise\udresults in a dynamic way. As a consequence, the web service\uddiscovery process which is based on the proposed approach\udgives a robust and precise results in a dynamic way
