Web Services are mounting as an inventive mechanism for rendering services to subjective devices
over the WWW. As a consequence of the rapid growth of Web Services applications and the plenty of Service
Providers, the consumer is facing with the inevitability of selecting the “right” Service Provider. In such a
scenario the Quality of Service (QoS) serves as a target to differentiate Service Providers. To select the best
Web Services / Service Providers, Ranking and Optimization of Web Service Compositions are challenging
areas of research with significant implications for the realization of the “Web of Services” revelation. The
“Semantic Web Services” use formal semantic descriptions of Web Service functionality and interface to enable
automated reasoning over Web Service Compositions. This study from its experimental results revealed that
the existing Semantic Web Services faces a few challenging issues such as poor prediction of best Web Services
and optimized Service Providers, which leads to QoS degradation of Semantic Web. To address and overcome
these identified issues, this research work is calculating the semantic similarities, utilization of various Web
Services and Service Providers. After measuring these parameters, all the Web Services are ranked based on
their Utilization. Finally, our proposed technique, selected best Web Services based on their ranking and placed
in Web Services Composition. From the experimental results, it is established that our proposed mechanism
improves the performance of Semantic Web in terms of Execution Time, Processor Utilization and Memory
Management.
