Web Service Antipatterns Detection Using Genetic Programming

Service-Oriented Architecture (SOA) is an emerging paradigm that has radically changed the way software applications are architected, designed and implemented. SOA allows developers to structure their systems as a set of ready-made, reusable and compostable services. The leading technology used today for implementing SOA is Web Services. Indeed, like all software, Web services are prone to change constantly to add new user requirements or to adapt to environment changes. Poorly planned changes may risk introducing antipatterns into the system. Consequently, this may ultimately leads to a degradation of software quality, evident by poor quality of service (QoS). In this paper, we introduce an automated approach to detect Web service antipatterns using genetic programming. Our approach consists of using knowledge from real-world examples of Web service antipatterns to generate detection rules based on combinations of metrics and threshold values. We evaluate our approach on a benchmark of 310 Web services and a variety of five types of Web service antipatterns. The statistical analysis of the obtained results provides evidence that our approach is efficient to detect most of the existing antipatterns with a score of 85% of precision and 87% of recall.
