Towards pattern-based service identification

Service-Oriented Architecture is a promising architectural approach to solve the integration problem originated by business process integration and automation requirements. he identification of the adequate services for the service architecture solution is a critical issue. Architecture abstractions, such as patterns, can capture design knowledge and allow the reuse of successful applied designs. The continual rise of abstraction in software engineering approaches have been a central driver of this work, placing the notion of patterns at business domain level. In this paper we propose a set pattern-based techniques for service identification. Graph-based pattern matching and pattern discovery are proposed to recommend the scope and granularity of services on process-centric description models. Matching of generalised patterns and hierarchical matching are discussed.
