Dynamic tags for dynamic data web services

Abstract

Service descriptions play a crucial role in Service-oriented Computing (SOC), especially with respect to service discovery and selection, service composition, and service replacement. Service providers have been the primary source of these descriptions, such as WSDL, WADL, WSMO. However, it has been observed that service providers tend to release poor service descriptions about their offered web services, because they focus on the implementation aspects of their web services. However, efficient service discovery requires rich service descriptions. Several approaches have been proposed to enrich service descriptions using human-generated or automatically-extracted annotations, such as tags. For data web services, e.g., list of countries, recent news, new publications, etc., such useful annotations can be also generated through service invocation analysis. In this work, we introduce a dynamic tag generator that analyzes service invocations and generates tags to annotate the invoked web services. The generated tags are then used in service discovery to enhance the quality of the result list.
