A Two-Layer Multi-dimensional Trustworthiness Metric for Web Service Composition

摘要

Web service composition is a promising area to revolutionize the collaboration among heterogeneous applications. Trust is recognized as an important topic in this research area. In this paper, we propose a two-layer multi-dimensional metric to represent the trustworthiness of web service composition programs. We explored several dimensions for both composition level and service level and finalize the metric, as an indicator, to represent the trustworthiness of the automatic service composition. We also propose a method to transfer the multi-dimensional metric into a single value for comparison purpose. A simulation experiment shows that the proposed metric shows better results than the empirical judgement based on past experiences.
