Recommending Web Service by Predicting Quality of Service using Hidden Markov Model

Owing to rapid growth of web services in service-based systems, the user should be provided with efficient service quality evaluation methods. Service quality is one of the most important features of software quality to predict the overall performance that helps to decide which web service should be manipulated. Both reliable and unreliable users are contributed by the service quality values leads to inaccuracy of the forecasting outcomes. To overcome this problem, we proposed the approach to detect the forecasting results accurately in unknown web service quality values using Matrix Factorization by Reputation with Hidden Markov Model (HMM). The experimental outcome shows that our proposed approach has improved accuracy to predict the reliable and unreliable users with other existing approaches.
