As the number of web services has increased, the number of services with the same functions has steadily risen. Consequently, many QoS (Quality of Service)-based service selection algorithms have been proposed to determine which service should be selected among those with the same functions. The prediction accuracy of the QoS attribute depends on the selection algorithm. In addition, the appropriate selection algorithm depends on the type of domain. For example, a stock notification service, which relies on real-time transactions, should employ a selection algorithm with a highly accurate response time. However, an automated method to recommend the optimal service selection algorithm has yet to be established. In this paper, we propose a method to recommend selection algorithms.
