AADSS: Agent-Based Adaptive Dynamic Semantic Web Service Selection

摘要

At present, Web Services invocation follows the “bind-once-invoke-many-times” pattern, while the Web Services run in a failure prone environment. Therefore, Web Services are not actually used on a large scale in real business world which calls for high robustness and trustworthiness. To solve this problem we propose an Agent-based Adaptive Dynamic Semantic Web Service Selection framework, called AADSS, in which Web Service consumers can dynamically select the “right” service, and adaptively change the bound services according to the real-time conditions such as QoS properties values, service reputation ranking scores and so on. We also describe a four-phase semantic web service selection strategy for this dynamic selection.
