Normally, the web service discovery mechanisms in web-sites have a trade-off between being Quality-driven or transaction cost-driven As goals of our paper, we decide upon several factors including the above-mentioned Quality and Transaction cost factors along with the parameters under each factor and use a priority-based greedy approach to involve minimum number of factors to achieve maximum efficiency in the web service discovery. We also present a model with QoS parameters which in a great way help in rating the web services with the end user's perspective on the basis of three levels of views, namely the business level view, Service level view and System level view. In this paper, we've broadly discussed around twenty eight parameters categorically falling under all the above-mentioned factors. To reduce the complexity of involving all the parameters we follow the mechanism of Greedy approach to evaluate the parameters and estimate the criteria rank for each and every parameter. The core principle of the Greedy approach, in general, is to involve minimum number of input data to achieve the maximum efficiency in the final optimized result.
