Context-based transactional service selection approach for service composition

Building applications dynamically from individual services offered by different organizations is one of the opportunities that Service-oriented Architecture (SoA) provides. With increasing number of providers, there is a choice among several functionally equivalent services resulting in a need to select the most appropriate ones in terms of Quality of Service (QoS) and transactional properties. In this paper, we propose a new web service composition approach bringing together the ideas of dynamically selecting services based on context with techniques to ensure that transactional properties are met across the application.
