Service mediation provides an effective way to integrate a service requester and a service provider, by reconciling the mismatches between the two. The techniques to assess the mediation degrees of services, to analyze irreconcilable mismatches, and to provide resolutions for irreconcilable behavioral mismatches are therefore essential. To address these challenges, we introduce in this paper two quantifiable metrics, called
, to evaluate the feasibility and complexity of mediating a requester and a service. We also propose a pattern-based approach for analyzing service behaviors that cannot be automatically mediated. We further offer resolutions for each irreconcilable mismatch pattern, which help developers to adjust and improve the service behaviors to fulfill the interaction requirements.
