Customer Churn is the major issue that faces by the Telecommunication industries in the world. Churn is the activity of customers leaving the company and discarding the services offered by it, due to the dissatisfaction with the services. The main areas of this research contend with the ability to identify potential churn customers, cluster customers with similar consumption behavior and mine the relevant patterns embedded in the collected data. The primary data collected from customers were used to create a predictive churn model that obtain customer churn rate of five telecommunication companies. For model building, classified the relevant variables with the use of the Pearson chi-square test, cluster analysis, and association rule mining. Using the Weka, the cluster results produced the involvement of customers, interest areas and reasons for the churn decision to enhance marketing and promotional activities. Using the Rapid miner, the association rule mining with the FP Growth component was expressed rules to identify interestingness patterns and trends in the collected data have a huge influence on the revenues and growth of the telecommunication companies. Then, the C5.0 Decision tree algorithm tree, the Bayesian Network algorithm, the Logistic Regression algorithm, and the Neural Network algorithms were developed using the IBM SPSS Modeler 18. Finally, comparative evaluation is performed to discover the optimal model and test the model with accurate, consistent and reliable results.
- ItemStandard Web Application for Flight Booking(NSBM Green University, 2018-08-25) Jayasinghe, T.; Kumara, B.T.G.S.; Dhanapala, W.W.G.D.S.; Kariapper, R.K.A.R.Web services are loosely coupled software components that are a popular implementation of the service oriented architecture. Web services have been extended to give value-added customized services to users through service composition. Online flight booking is a major application of Web service. Travelers are also relying more on travel review sites when booking. However, one of the major problems of development of the online reservation system is when we are connecting web services from different web service providers then we have to develop different programs to calling each of them. Because, each service providers provide different data formats as their response data. Therefore, Engineers have to learn about that from the bottom of the line. Another problem of the existing online reservation systems is reservation systems are different with each other. That is increasing the complexity of the system when using the consumer. There are not available travel agent web site standards. When a new system is built it’s hard to find the proper standard methodology. So that makes very hard to developers, architectures, business peoples to develop a system that internationally accepted. This research studies mainly focusing on defining those standards and each and every travel agency sites will be on the same standards so that the users and other parties who are involved in the travelling purpose will find very easy to use this reservation systems because there is the same standard which is internationally accepted
