Personalized Service Discovery and Composition

With the prevalence of Service-Oriented Architecture (SOA), end-users, who are not familiar with SOA standards and tools, want to customize services to fulfill their daily activities. However, it is challenging for end-users to get involved in the service composition, due to the in-depth knowledge needed for SOA standards and techniques. To help end-users compose services for their daily activities, we propose an approach that shields end-users from the complexity of SOA standards and automatically generates composed services by specifying a goal using keywords. We expand the meaning of a user’s goal using ontologies and derive a group of keywords for discovering services in order to achieve a user’s goal. We also detect contextual environment of a user and personalize the service composition to meet a user’s situational needs. A prototype is developed as a proof of concept to show that our approach enables nonexpert end-users to discover and compose services easily.
