In this phase, the data is obtained from all possible data sources (Miller and Mork, 2013; Chen et al., 2014). For instance, in order to predict the customer churn in Telecom, data can be obtained from CDRs and opinions/complaints of the customers on Social Networking Sites such as Twitter (in the form of tweets) and Facebook (opinions shared on the company’s Facebook page). The most commonly used methods are log files, sensors, web crawlers and network monitoring software (Chen et al., 2014).
