Market-Optimized Service Specification and Matching

Abstract

Various approaches in service engineering are based on service markets where brokers use service matching in order to perform service discovery. For matching, a broker translates the specifications of providers' services and requesters' requirements into her own specification language, in order to check their compliance using a matcher. The broker's success depends on the configuration of her language and its matcher because they influence important properties like the effort for providers and requesters to create suitable specifications as well as accuracy and runtime of matching. However, neither existing service specification languages, nor existing matching approaches are optimized in such way. Our approach automatically provides brokers with an optimal configuration of a language and its matcher to improve her success in a given market with respect to her strategy. The approach is based on formalized configuration properties and a predefined set of configuration rules.
